Description of the drug, what it is, release form, toxicity
The product contains a potent substance - penconazole, which is mainly used for powdery mildew. The package contains a substance concentration of 100 grams per liter.
The drug works as follows:
- Penconazole blocks the spread of fungus and prevents the growth of spores. Even with a small concentration, the pathogenic fungus dies and stops reproducing. The effectiveness of the drug is that it is immediately absorbed into the plant, so no weather conditions or temperature changes affect it.
- The only drawback is the storage limitation. The shelf life is no more than 4 years. You should not use an expired product, since low-quality chemicals make the fruits inedible and poisonous and can cause irreversible damage to the plant.
- The chemical is sold in sachets with a dosage of 3 milligrams, or ampoules with a dosage of 2 milligrams. If you need to treat a large area, then Topaz can be bought in a 1-liter plastic bottle and diluted in accordance with the instructions.
The active substance is toxic
Although the drug is less dangerous for humans than for animals or insects, it is important to take precautions when using it and keep the substance away from children
Active substance and mechanism of action
"Topaz" is a one-component drug for combating powdery mildew, the main active ingredient of which is penconazole. The concentration of penconazole in Topaz is 100 g per 1 liter of the drug.
The mechanism of action of this substance is to completely stop the reproduction of the fungus by stopping the germination of its spores. As a result, the spore growth tube does not germinate into the plant tissue and dies. It is noteworthy that such an effect on pathogenic fungi requires a very low concentration of penconazole. In addition, the substance is literally immediately absorbed by the plant, so treatment can be carried out even on rainy days. Temperature changes also do not affect its effectiveness (in spring and autumn, spraying plants is allowed even on days when the night temperature drops to -10°C).
Fungicide Topaz instructions for use of the drug
The plant protection product Topaz is a fungicide approved for use in agriculture, subject to strict adherence to the safety and dosage rules specified by the manufacturer.
The drug is effective against the following diseases:
- powdery mildew;
- oidium;
- fruit rot;
- purple spot;
- gray rot;
- rust.
Topaz has a long-term effect on pathogenic microorganisms, which makes it possible to significantly reduce the number of pesticide treatments. Next, we’ll look at how to use Topaz for plant diseases: instructions for using the drug in your personal household.
The drug is a concentrated liquid packaged in plastic containers with a capacity of 1 liter or ampoules with a volume of 2 ml. Plants are treated with a working solution, the concentration and consumption of which is calculated based on the phase of the disease and the degree of development of the crop.
To create a base solution, mix the concentrate with water in the required proportions. Rules for creating a base solution. Pour 1 liter of water into a 10 liter container, add 1 ampoule of Topaz and mix thoroughly. After complete dissolution of the drug, add water to the full volume (10 l).
It is important to understand that vegetable crops and indoor plants are treated with a pesticide only when there are visible manifestations of the disease. Fruit trees and shrubs, in addition to direct treatment of fungal infections, can be subjected to two preventive treatments, before and after flowering
Fruit trees and shrubs, in addition to direct treatment of fungal infections, can undergo two preventive treatments, before and after flowering.
Topaz for grapes
It is used in cases of crop disease with podium, a fungal infection in which the fruits and leaves of the crop become covered with a visible white coating. Another manifestation of this disease is curling and premature wilting of the leaves of the vine.
Treatment is carried out by spraying the vine with a working solution 4 times at the first manifestations of the disease. Preventive treatments: 1 time immediately after swelling of the buds and 1 time after flowering. Base solution concentration: 2 ml. drug per 10 liters of water.
Topaz for gooseberries
Many novice gardeners wonder when to treat gooseberries with Topaz in order to avoid infectious diseases of the crop. Gooseberries are one of the fruit shrubs that are susceptible to powdery mildew. Treatment should begin at the first manifestations of the disease. To treat gooseberries, it is necessary to treat the leaves and shoots with a pesticide solution in a concentration of 2 ml of Topaz per 10 liters of water.
In order not to wait for signs of gooseberry disease, experts recommend carrying out preventive spraying before and after flowering. The total number of treatments should not exceed four.
Topaz for powdery mildew
Vegetable crops, berry bushes and fruit trees suffer from this disease. To treat vegetable crops, it is necessary to carry out treatments with a base solution with a concentration of 1.5 ml. concentrate per 10 liters of water. To treat fruit trees and shrubs, no more than four sprays are carried out with a Topaz solution with a concentration of 3 ml per 10 liters of water.
Trees and shrubs are prevented from powdery mildew before and after flowering. As a rule, 2 sprays are enough to prevent the spread of infection.
Topaz for fruit rot
Fruit rot is a consequence of infectious damage to fruit trees by spores of the fungus Monilia. A characteristic feature of this disease is the withering of fruits, leaves and young shoots with the appearance of a white coating on their surface.
Treatment of “fruit rot” is identical to the fight against powdery mildew: treatment of the affected areas with Topaz solution: 3 ml of the drug per 10 liters of water.
Preventive treatments are carried out twice: before buds open and after flowering.
Topaz for rust
The disease most often affects vegetable crops, indoor plants and flowers growing in greenhouses and open ground. The infection appears in the form of pastulas that cover the leaf blades.
In the advanced form of the disease, the foliage wilts, the pastulas on which burst and fungal spores are spread to neighboring areas. It is better to start fighting the infection at the first symptoms of the disease.
Treatment consists of treating plants with a fungicide solution:
- For vegetable crops – 2 ml of concentrate per 10 liters of water.
- For indoor plants – 2 ml of the drug per 5 liters of water.
As a rule, to cope with rust fungus, it is enough to carry out no more than three therapeutic sprays.
Description and properties of the drug
Topaz belongs to the class of fungicides of the third hazard category. Refers to a type of systemic drugs from the group of triazoles that disrupt the processes of sterol biosynthesis in a variety of fungi. Thanks to this, it is effective both for prevention and for various degrees of invasion on plants (see video).
A targeted effect on the pathogen is achieved through the substance penconazole. Helps in the fight against various diseases:
- powdery mildew;
- rust on leaves;
- gray rot;
- purple spotting;
- oidium;
- coccomycosis.
Suitable for processing ornamental, fruit, berry and vegetable crops, including:
- cucumbers;
- gooseberry;
- currant;
- roses;
- cherry;
- peach.
Purpose of the drug and its benefits
Powdery mildew appears quickly on a plant and spreads throughout it at an incredible speed. “Fluffy” spots of various shades appear on the leaves and shoots. It can be white or pink, gray or brown. Depending on the type of plant.
In addition to powdery mildew, Topaz actively fights the following diseases:
- oidium;
- gray rot;
- rust;
- scab;
- fruit rot;
- purple spot;
- septoria.
Rust is terrible for garden and potted roses, as well as carnations. Oidium affects grape bushes. Fruit rot is dangerous for a delicate and quivering peach.
The advantages of the drug include its versatility during processing. Can be used throughout the day, regardless of the weather. Moisture-resistant properties allow for treatment before rain.
In early spring and late autumn, with a possible sharp drop in temperature, even at -10 ° C, Topaz works inside the plant, preventing fungi from developing.
Fungicide Topaz can be used even in the rain - it is not washed off by precipitation.
The drug is suitable for many crops at any stage of plant development. Not phytotoxic. The effect of the drug lasts almost two weeks after treatment, so there is no need for repeated treatments during this period of time.
The economical consumption of the finished solution allows you to significantly save on processing the entire garden. Friendly compatibility with other fungicides and pesticides allows you to create a health “cocktail” for treating plants from a range of diseases and pests in one go.
Description, properties, mechanism of action of drugs
The active ingredient penconazole, included in Topaz, successfully fights fungal infections of all parts of plants. The drug, entering the plant, mixes with its juice and circulates throughout the plant, attacks fungal pathogens and stops their reproduction. The mechanism of action of the fungicide gives results within a few hours after administration of the drug.
Release form and composition
Topaz fungicide is available in liquid form. You can find containers with volumes from 2 to 5000 milliliters. Topaz is presented in the form of an emulsion that must be diluted with water. The fungicide itself consists of one substance, penconazole. Penconazole is a powder, but in garden stores the substance is sold as a 10% concentrate. It is worth noting that the powder is poorly soluble in water.
Advantages and disadvantages
A strong chemical like Topaz has many benefits, but it is not without its drawbacks.
Advantages:
- suitable for a large list of plants;
- does not have a toxic effect on the plant itself;
- begins to act within a couple of hours after spraying;
- Can be used with some other chemicals;
- There is no clear schedule for treating plants; you can apply it at your own discretion.
Flaws:
- the drug itself is toxic and may pose a danger to birds, fish, and insects;
- accumulates in the soil.
Purpose and application
Fungal diseases of plants
This drug should be used without waiting for the onset of the disease. Plants susceptible to diseases such as powdery mildew, fruit rot, coccomycosis and purple spot should be treated according to a scheme developed specifically for them.
After the fruits appear, you should not carry out processing in order to avoid negative consequences for human health.
Fungicide Topaz compatibility with other drugs
The compatibility of the Topaz chemical with other chemicals may not be specified in its instructions for use, but for comprehensive prevention of various plant diseases this must be done regularly. For this purpose, the drug “Topaz” for plants can be mixed with such products as:
- "Kuprosat", which allows you to fight late blight and circosporosis;
- "Topsin-M", which is used against scab, moniliosis, gray rot, anthracnose;
- “Kinmiks” is a drug for combating larvae of agricultural pests;
- "Chorus", used for the prevention and treatment of Alternaria, fruit rot, clasterosporiasis, coccomycosis.
All of these drugs are classified as fungicides, but they differ from each other in the active substance. Thanks to this, when combining drugs, you do not have to reduce the dose, but you can use them according to the instructions.
Advantages and disadvantages
The use of the drug Topaz for plant diseases allows you to obtain healthy agricultural products, and preserve attractiveness and health in ornamental crops.

What products can the fungicide Topaz be combined with?
- Kinmiks
- Kuprosat
- Topsin-M
- Horus
Without exception, all chemicals require careful and careful handling. Fungicide Topaz is no exception:
- The container used is used ONLY FOR SOLUTION
- The fumes are toxic. Respirator protection is required.
- If the product gets on your skin, rinse with plenty of water.
- For minor pore poisoning, you need to take activated carbon with 0.5 liters of water.
- In case of food poisoning - urgent gastric lavage
- It is strictly forbidden to drink, smoke or eat food when working with the chemical.
- Topaz containers (ampoules) cannot be disposed of with regular waste. They should be burned or buried away from water sources.
The storage location for Topaz fungicide should be dark, isolated, away from food, medications and, of course, children.
Topaz is popular due to its effectiveness and reasonable price. Using Topaz, strictly following the instructions, will help preserve the harvest and not cause harm to the environment.
Precautionary measures
Without a respirator, treating plants with Topaz is dangerous to health. After use, the container must be washed thoroughly so that no one has time to use it. In high concentrations, the product and its vapors are toxic. In case of contact with mucous membranes, eyes, or skin, rinse immediately with plenty of water.
The drug should not be allowed to enter water bodies, as it poses a threat to fish. The shelf life of Topaz is 4 years. It is unacceptable to treat plants with expired fungicide; this risks an uncontrolled increase in toxicity. To store Topaz, it is necessary to set aside a place inaccessible to children and animals, away from food supplies and medicines.
Advantages of using Topaz in a summer cottage
As you have seen, Topaz is a fungicide with a very wide range of applications. Even though many analogues of Topaz can be found on the market today, the choice should be given to this drug, since it has a number of advantages:
- “Topaz” is precisely the chemical that has a long period of influence on the spores of fungal diseases. Thanks to this, preventive spraying can be done only twice during the month, reducing the pesticide load on plants and soil.
- Instant absorption of the drug by plants makes it possible to stop the growth of fungal spores within 2-3 hours after treatment.
- The rate of use of the drug is very low, so one sachet is enough for almost the entire season, even if its use is necessary both in the garden and in the vegetable garden.
- "Topaz", unlike other drugs, can be used for a very large number of plants.
- “Topaz” is used at almost all stages of the plant growing season: from the beginning of growth to the beginning of fruit formation. Even if it comes into contact with ripe fruits, the toxic effect of the drug remains minimal, which allows them to be eaten without fear of poisoning.
- “Topaz” is compatible with many other drugs, which allows it to be used for complex plant treatments.
Features of use
Like other systemic fungicides, Topaz does not form a film on stems and leaves. Penconazole is absorbed into the plant and carried along the sap throughout the vine. The growth of fungal spores stops due to the suppression of the process of sterol biosynthesis and recovery occurs. The ambient temperature for this drug is not so important, since it works even at negative temperatures, but there may be problems associated with freezing of the working solution.
Topaz can be used as an independent remedy or in combination. In combination with fungicides, there is no need to reduce the dosage. The drug will continue to perform its function without reacting with the components of another fungicide. Practice shows that Topaz copes well with the task on its own, so in most cases, combination with other agrochemicals is not necessary.
If in early spring you simultaneously treat a section of soil within the radius of the root system, this will be an excellent preventive measure against spores that have successfully overwintered; at least the vine will not get burned, as when sprayed with iron or copper sulfate.

Composition and action
The active ingredient of the Topaz fungicide is the synthetic triazole penconazole (formula in the figure) at a concentration of 10% (100 g/l). Some popular sources attribute the “unnaturalness” of its DV to Topaz’s shortcomings. Indeed, there are no analogues of penconazole in living nature. But most of the poisons, drugs, chemicals for torture and other rubbish are isolated from herbs and trees - it couldn’t be more natural. Everything is poison and everything is medicine, you just need to know what it is and how to handle it.
The formula of penconazole shows that during its breakdown, substances that can have a long-term effect on the environment cannot, in principle, be formed. Nitrogen, given the insignificant dosages of the drug, can be ignored, and the chemically very active chlorine will instantly find “partners” for the formation of harmless stable compounds.
The effect of penconazole on pathogens is specific: it targets germinating spores with sniper precision. If, say, Ordan is called a “semi-systemic” pesticide (it penetrates plants, but does not spread throughout them), then Topaz is a “supersystemic” pesticide. In plants, it is concentrated in young tissues immediately after the growth point, and follows it as the protected object develops. But in this same, most vulnerable zone, spores of powdery mildew and physiologically similar fungi germinate. Using military terminology, Topaz calculates the enemy landing site, sets up an ambush there and destroys the enemy, preventing him from deploying battle formations. Which, as you know, is the key to the complete success of the operation.
The best fungicides in the fight against grape diseases: description, action, application
Topaz can be treated for therapeutic and preventive purposes. The fungicide is used against diseases caused by pathogenic flora.
For vegetables
Vegetables are processed when the first signs of a fungal infection appear. During the growing season, vegetable crops can be processed up to 4 times.
Important! It is prohibited to use Topaz fungicide for more than 3 years on one planting site.
Vegetable crops are treated by spraying or overhead watering on the leaves. 1.5 ml of the drug is diluted in a bucket (10 l) of clean water. This amount of solution is enough to treat 100 square meters. m of planting area against powdery mildew.
If signs of powdery mildew on vegetables persist, the treatment is repeated after 2 weeks according to the instructions.
Fruit rot often affects peach, pear, apple and cherry trees. Due to the influence of pathogenic flora, the fruits on the trees dry out, remaining on the branches. The disease spreads in a short time throughout all crops in the garden, destroying the harvest.
Powdery mildew affects leaves, branches and young shoots. It appears as a whitish coating on parts of plants. Gradually, deformation and death of the affected branches occurs.
To combat powdery mildew and fruit rot, trees are treated before flowering and after for prevention. You can spray fruit crops during the period of fruit formation according to the instructions for use
To protect young seedlings, up to 2-3 liters are required for each specimen. The solution is prepared at the rate of 1 ampoule (2 ml) per 5 liters of water. The consumption of protective solution for mature trees is from 5 to 7 liters per tree.
Important! If protective measures were carried out during the fruiting period, then be sure to wash the fruits with plenty of warm water before eating.
Berry garden shrubs often suffer from powdery mildew. The first signs of the fungal culture appear on the lower branches with a white coating. Treatment must be carried out immediately after detection of the disease. For preventive purposes, berry gardens are treated at the beginning of flowering and after it. The instructions prohibit the use of Topaz fungicide later than 3 weeks before ripening and harvesting the berries.
The solution consumption for a medium-sized bush is from one and a half to two liters. The concentration depends on the degree of damage. For prevention, use 1 ampoule per 20 liters of water. For medicinal purposes, the proportions can be increased, but not more than 20% of the standard dosage.
The number of treatments should not exceed four times during the entire growing season. Final sprays can be carried out after harvest and as preparation for winter. But the air temperature, according to the instructions for use, should not fall below - 10 ° C.
For grapes
Against oidium on grapes, the fungicide Topaz is used no more than 4 times per season. The first treatment is carried out for preventive purposes after the buds bloom on the vine. The solution is applied to the leaves by spraying. The drug is diluted at the rate of 1 ampoule per bucket of water. To cultivate a grape planting area of 10 square meters. One and a half liters of ready-made solution is enough.
If necessary, re-treat after flowering according to the instructions for use.
For strawberries
Strawberries are more susceptible to powdery mildew than other crops. Especially often, a white coating on the leaves appears during rainy periods or with excessive watering. Strawberry leaves dry out from exposure to a fungal infection, the berries crack and turn brown.
Due to rust, which affects the green parts of strawberries, the yield of the bushes decreases. The disease manifests itself as brownish spots on the leaves.
Strawberries are processed by spraying on the leaves before flowering and after harvesting. In this case, experts recommend removing the affected parts of the plants and burning them.
To treat strawberries, an ampoule of Topaz fungicide is diluted in 15 liters of water. This volume of solution is enough to treat plantings over an area of 100 sq.m.
For roses
The inhabitants of the rose garden suffer from fungal diseases very often. Improper watering or frequent rains lead to the leaves becoming covered with a white coating of powdery mildew, spotting and rust. The foliage loses its decorative appearance, the buds become smaller and flowering becomes scarce.
At the slightest sign of fungus action, gardeners begin treating rose bushes with fungicides. Topaz copes well with the pathogen in the early stages. It is also indispensable as a preventive measure when covering roses for the winter.
Roses are less susceptible than others to the action of fungicides. Therefore, the dosage of the solution should be increased, as indicated in the instructions for use. Take two ampoules of Topaz fungicide per bucket of water, or 4 ml if the solution was purchased in a large container.
Roses are sprayed in the evening no more than three times per season. You need to thoroughly moisten the leaves on both sides. The interval between treatments should not be less than 3-4 weeks.
For flowers
According to the instructions for use, Topaz fungicide is recommended for protecting indoor flowers from fungal diseases. Plants are sprayed in a ventilated area when signs of disease appear on flowers and leaves. The optimal concentration of the solution for treating flower crops in the room is 3 ml per 5 liters of water. To protect against rust on the leaves of orchids, violets and other plants, you can spray the leaves no more than 3 times with an interval of 3 weeks.
Important! It is necessary to restrict access to the premises to children and pets for several hours.
To treat flowers in a flower bed, a solution is prepared from two ampoules (4 ml) of Topaz fungicide per bucket of water. Apply in the evening in calm weather. Repeated spraying of the flower bed can be done after 20-25 days.
Important! To protect coniferous trees (juniper, pine, thuja), the instructions for use recommend the fungicide Topaz K.
Fungicides are synthetic drugs whose action is aimed at suppressing infections caused by fungi. Among them: scab, anthracnose, white rot, gray rot, grape mildew. The products are used for the prevention and treatment of grapevine diseases.
Fungicides are non-toxic and generally do not harm plants and humans. There are three types of such preparations: systemic, contact, complex.
The article will talk about the important features of using fungicides for grapes and popular preparations for garden treatment.
Grapes are considered a rather capricious crop. Most high-yielding varieties have weak immunity to pathogenic microflora. Main diseases of berry crops:
- anthracnose;
- mildew;
- scab;
- white, gray rot.
The fungal infection develops quickly; in a few days it can spread to seedlings growing nearby; in a chain reaction, after 2 weeks the entire vineyard will be infected. The yield of diseased bushes decreases, in the worst case, the plant dies.
Preventive treatment with fungicides does not allow fungal colonies to grow, destroying pathogenic microflora at the initial stage of development. Massive damage to grapes is much more difficult to eliminate than to prevent the disease.
The mechanism of action of fungicides depends on the chemical composition, but all of them are aimed directly at the cells of microorganisms. By influencing biological processes, drugs block enzymes involved in the reaction and inhibit the synthesis of ergosterol or lipids - the building material of membranes. Some alanine-based chemicals inhibit the production of nucleic acids and proteins.
Important! Fungicides are harmless to grapes and humans, since the active substances do not accumulate in the berries.
To get the expected result from the drug Topaz for plants, you should read the instructions for use.
Preventive treatment is carried out with a less concentrated solution; for this, one ampoule is dissolved in a bucket of water. For medicinal purposes, a higher concentration of the drug is required.
An important condition for spraying is weather with a stable absence of strong wind and precipitation. If it rains or snows 3-5 hours after spraying, there is no need to repeat the procedure; during this time the substance will have time to be absorbed into the body of the plant. Subsequent spraying is carried out with a pause of 2 weeks.
The application rate of Topaz fungicide is determined by the type of crop and phase of development, as well as the type of disease and degree of infection. Usually, to prepare the working fluid, the specified dose of the drug is diluted in a certain amount of clean water before use. It is not recommended to store the prepared solution for more than a day, as it will lose its properties.
Place of processing | How to divorce | Consumption rate per 1 m² |
Open ground | 1.5-2 mg per bucket | 100 ml |
Greenhouse, greenhouse | 3.5 mg per 10 l | 200 ml |
Before treatment, affected leaves must be torn off and burned. If signs of the disease persist, the procedure is repeated every 2 weeks four times.
Fruit trees
Apple, pear, cherry and peach trees are susceptible to attacks by powdery mildew and fruit rot. It is easier to prevent infection than to treat it for a long time.
For prevention, 2 ml of the drug is dissolved in a bucket of water and sprayed onto the crowns of trees before the buds open and after flowering.
The fight against parasitic fungus begins with the appearance of the first signs of the disease. To do this, prepare a working solution of 3 milliliters of Topaz and 10 liters of water. You need to spray two to four times every 14 days with a consumption of 2 liters for young trees and 5 liters for adults.
Berry bushes
Gooseberries, raspberries and currants are affected by powdery mildew. To destroy the phytopathogen, 1 ampoule of the drug is dissolved in a bucket of water and sprayed at the rate of 1-2 liters per bush. Treatment is carried out once every 2 weeks, only 2-4 sprayings per season. It is better to carry out the last procedure 20 days before picking the berries.
To protect the bushes from infection with mycosis, they are sprayed with the same solution twice: during the formation of buds and after the formation of the ovary.
Grape
Vineyards suffer from oidium. The first treatment is carried out when yellow swellings and a white coating form on the foliage, the inflorescences fall off, and the vine withers. To destroy the fungus, 2 to 4 sprays are carried out from an ampoule of the drug diluted in a bucket of water. For 10 sq. meters will require 1.5 liters of liquid.
Features of the use of fungicide
The use of Topaz fungicide does not cause any difficulties
It is important to maintain proportions and not forget about precautions:
- The drug is sold in ampoules. One ampoule should be diluted in a small amount of water, and then water should be added to 10 liters. If indoor plants are treated, the ampoule is diluted in 5 liters of water.
- After this, the plants are completely treated with the solution. This should be done in calm weather so that part of the drug does not evaporate immediately. It is advisable that no precipitation is expected on the day of spraying.
- The solution is not stored. It must be used within a day after preparation; it should not be left until the next spraying. Treatment of plants with Topaz fungicide is carried out no more than once every two weeks (maximum - once every 10 days).
- You can treat plants (fruit trees, shrubs) for prevention. In this case, the first spraying is carried out in the spring before flowering, and the second after flowering. For prevention purposes, 2-3 times will be enough.
- If we talk about vegetable crops and indoor plants, the fungicide is used only when the disease begins. The sooner treatment begins, the better. It should not be forgotten that all infected leaves must be removed, otherwise the fungicide will not work.
- Berry bushes are processed only twice: when the buds have just begun to form and after harvesting.
- Each disease may require an individual approach. For powdery mildew, 2 ml of the drug per 10 liters of water is enough, but rust will require a double dose (4 ml per 10 liters).
- You can dose the drug depending on the number of plants being treated. This is done using a regular medical syringe. For example, 1 or 2 ml of the drug is drawn from an ampoule into a syringe and dissolved in the appropriate proportion of water.

Safety precautions
Topaz is a slightly toxic chemical, so you should follow some recommendations:
- Use protective equipment for skin, eyes and respiratory organs,
- It is optimal to choose a plastic container for the solution.
- If the substance comes into contact with mucous membranes or skin, remove the substance with running water.
- If ingested, drink 4 tablets of activated carbon and induce vomiting.
- If symptoms of intoxication occur, consult a doctor.
- Used packaging must be burned.
How to use Topaz correctly
The use of the drug is possible in accordance with the instructions. Only in this case can you achieve the desired effect without destroying the plant. Topaz is most often used to get rid of powdery mildew, which can affect almost any plant.
Use of fungicide for preventive purposes
Topaz is used as a prophylactic for various plants:
- currants, grapes, cucumbers, gooseberries, strawberries must be treated with Topaz in a very low concentration: 1 ampoule of 2 ml per 10 liters of water;
- roses and indoor plants in the flowering phase are treated with a solution with a higher concentration (due to their greater resistance to fungicides): 1 ampoule of 2 ml of product per 5 liters of water;
- Treatment of plants planted in open ground should be carried out in calm, dry weather. Under such conditions, the product is completely absorbed into plant tissue and exhibits maximum effect. If, 3 hours after spraying, it starts to rain, then there is no need to re-treat, because during this time the product will have time to affect the fungus. Subsequent spraying is carried out after 2 weeks.
Effect of the drug on diseases
This remedy is indicated for use in the following fungal infections of plants:
Oidium. Since Topaz is a potent fungicide, 1 (2 ml) ampoule of the product diluted in 10 liters of water is used to treat grapes against oidium. Treatment must be carried out when initial signs of the disease appear and repeated after 14 days.
Rust. Roses and carnations are especially susceptible to this disease. You can heal flowers by treating them with Topaz solution diluted 4 ml to 10 liters of water.
Powdery mildew. It is equally dangerous for all plants: strawberries and cucumbers. A “Topaz” solution prepared from 1 (2 ml) ampoule and 10 liters of water can relieve a diseased plant from the disease. Spraying should be carried out at the first manifestations of the disease. To cure gooseberries from the American variety of powdery mildew, use a solution with the same dilution. When powdery mildew affects violets, it is necessary to remove all damaged parts and treat the plant with a concentrated solution (1 ampoule per 2 liters of water).
Fruit rot. It most often infects peaches. If the fruits are severely affected, then Topaz will not bring the desired effect.
Therefore, it is extremely important to prevent the disease by treating trees every fourteen days, starting from the moment the first leaves sprout. In this case, you should use 2 ml of the product diluted in 10 liters of water.
Release form and composition
The active substance of Topaz is penconazole. This is an organic compound from the class of triazoles, widely used for plant protection.
The drug is produced by the Swiss company Syngenta, which has branches in more than 90 countries. In Russia the company is represented by a subsidiary. Among the manufacturers of the drug are domestic companies Green Belt, August.
Since Topaz is used on farms, private farms and in areas that can only be processed with the help of aviation, the form of release may differ significantly. The drug is packaged in:
- sealed small bags (3 ml),
- ampoules 1-2 ml,
- bottles from 1 ml to 1 l
- canisters with a capacity of 5 liters.
Blue powder and solutions are available for sale. Topaz CE is an emulsion concentrate.
Topaz analogues:
- Diamond 100;
- Jack Pot;
- Kemistar;
- Thiophene Extra;
- Fulpas.
Method for preparing the working solution
Instructions for use are included with the drug. According to it, to prepare the working composition, Topaz is first stirred in a small amount of water, then water is added to the required volume. The result is a dispersed system; the chemical does not dissolve in water, but disperses in droplets. Therefore, it is necessary to intensively stir the composition for 3-5 minutes. The tank solution is used within the first 7-8 hours from the moment of preparation; it is not suitable for storage. The sprayer is shaken during treatment.
Plants are sprayed from spring to autumn, preferably in dry weather. The intervals between procedures are observed, taking into account the type of culture, the degree of infection with the fungus, and the type of infection. The maximum dose is used when there is a high incidence of disease; to prevent infection, the norm is significantly lower.
Application of Topaz on various crops
Berry and fruit trees are sprayed to prevent the disease, as well as during the treatment stage.
Vegetables and ornamental plants (including indoor flowers) are sprayed only in case of visible signs of infection.
Processing of fruit trees
Topaz is effective in the treatment of powdery mildew, as well as fruit rot. These diseases cause significant damage to gardens, quickly spreading throughout the plantings and leading to the destruction of the crop.
Spray:
- cherry;
- pear;
- apple trees;
- peaches.
For young trees, 2 liters of the prepared solution will be enough; for adults, 4-5 liters are consumed. Mixture proportions: for five liters of water – 1 ml of the drug.
When to till the garden? For prevention, Topaz is used at the beginning of bud formation or at the end of flowering. The total number of treatments per season is 4 times.
Treatment of grapes
The owners of grape plantations use Topaz for an insidious fungal disease of the crop - oidium. Swollen brown-yellow spots appear on the leaf blades of the vine, which leads to complete deformation of the leaves and falling of the inflorescences.
For prevention, two treatments are necessary:
- at the moment the first leaves appear;
- after the grapes bloom.
Ingredients: dilute 2 ml of fungicide per bucket of water, use 1.5-2 liters per 10 square meters of plantings.
Yagodniki
In the garden, almost all berry bushes are seriously affected by powdery mildew. It is effective to use Topaz at the initial stage of flowering of raspberries, currants, gooseberries, as well as at the first symptoms of infection.
Working solution: 1 ml per 5 liters of water, consumption – 1.5 liters per bush. For large bushes, the consumption rate is increased to two liters.
Vegetables
The drug Topaz is used to protect greenhouse and ground cucumbers suffering from powdery mildew. Usually one treatment with the solution is enough: 2 ml of suspension is diluted in a bucket of water.
The consumption rate is approximately 0.2-0.3 liters per square meter. meter in a greenhouse, 0.1 liters per the same area for cucumbers in beds. Repeated spraying no earlier than after 14-18 days if the symptoms of the disease persist.
Rose processing
Topaz is included in the list of fungicidal preparations used by flower growers to protect rose bushes. The crop is seriously suffering from an insidious fungus, so when the first signs of the disease appear, surgical treatment begins.
Treatment on leaves, solution: 4 ml of concentrate is diluted in a bucket. In total, during the summer season it is allowed to carry out 2-3 treatments with an interval of 20-25 days.
Treatment of flowers in flower beds
Diseases such as rust and powdery mildew are dangerous for ornamental plants in flower beds. Particularly often affected:
- violets;
- chrysanthemums;
- peony;
- irises;
- clematis;
- carnations;
- Snapdragon.
Having noticed the appearance of rusty, red-brown spots with a coating on the leaves, promptly spray the flowers with Topaz solution. The drug is mixed in water in the proportion per 10 liters of water - 3 ml of product. It is advisable to process flowers in cloudy weather.
Strawberry treatment
Large losses of tasty berries are possible when strawberries and wild strawberries are affected by powdery mildew. In rainy weather conditions, a white coating instantly covers the leaves and berries of the crop, leading to rotting of the fruits and drying out of the plants. Rust is dangerous, due to which the leaf blades of strawberries dry out and the yield of berries decreases.
Treatment with Topaz is effective only in the first stages:
- prepare a solution: 3 ml of concentrate per bucket of water;
- spray the bushes leaf by leaf.
For prevention, plantings are treated before flowering, as well as after picking berries. 2 procedures per summer will be enough.
Houseplants
Preventive treatments are not carried out; the product is used only if symptoms of powdery mildew or rust appear (on violets, orchids, ficus).
Solution: for five liters - 2 ml of Topaz. Spray the plants, ensuring the room is ventilated. Number of treatments – 3 times.

Hazard class 3 for humans (moderately hazardous substance) and hazard class 3 for bees. Manufacturer: Syngenta LLC, Switzerland. Shelf life is 4 years from the date of manufacture.
- mechanism of action of penconazole: suppresses infection at the time of spore germination and penetration of the growth tube into the leaf tissue.
- acropetal movement of penconazole - spreads through the vascular system beyond the plant growth point, i.e. gets into young growing shoots.
- It is effective in all weather conditions, therefore it is widely used on garden plants and indoor flowers.
- The fungicidal effect of Topaz manifests itself during the first 24 hours; the protective function is maintained over the next 10-14 days.
- one of the few powerful drugs approved for use on private farms and in apartments.
- Topaz is not phytotoxic.
- The fungicide is effective over a wide temperature range and can be used in early spring.
- Can be mixed with other pesticides, suitable for tank mixtures.
Application of topaz fungicide
The active ingredient topaz is highly effective, first of all, against the pathogens of powdery mildew, especially in cases of primary infection. Topaz is also widely used to treat fruit rot, purple spot, net spot, gray mold, rust, scab, septoria, cercosporellosis, oidium.
The prepared solution is thoroughly sprayed onto the plants in dry, windless weather.
Topaz on grapes and stone fruits (cherries, peaches, apple trees) is applied the first time before flowering, the second time after flowering. Only 3-4 treatments are allowed.
Topaz is used on vegetables and indoor flowers at the first signs of the disease.
The combination of drugs Topaz and Kuproxat is especially successful. It is necessary to take into account the possibility of the emergence of resistance to a fungicide, therefore in gardens where infections are most common (for example, when unreliable neighbors do not want to treat trees for scab), it is better to alternate Topaz with fungicides from other chemical groups.
Attention, fake! Due to the popularity of the Topaz fungicide, there are many counterfeit products on the market. Marketing managers of Syngenta LLC have repeatedly published an official conclusion on the detection of counterfeit
Consumption rates
2 ml of Topaz is calculated on average per 10 liters for various diseases, and only against rust the norm is 4 ml per 10 liters of water.
For use on indoor flowers, Topaz fungicide is best diluted in a small amount of water. The entire volume of the ampoule must be drawn into a 2 ml syringe, and then dosed the required amount, for example, 1 ml per 5 liters of water. Store the remaining drug in the syringe with the cap closed at room temperature, in the dark and out of the reach of children.
It is possible to increase the concentration by no more than 1.5-2 times, i.e. 3-4 ml of Topaz per 10 liters of water. The plants do not feel oppressed. If leaf lethargy appears, this may be a reaction to a violation in care, for example, to waterlogging of the soil.
Working fluid consumption rates: 2 liters for a small tree, up to 5 liters for a larger tree, 1.5-2 liters per bush (currant, gooseberry), vegetables - up to 5 liters per hundred square meters.
Toxicity of Topaz
Topaz is moderately toxic to bees and birds. Toxic to some species of fish and aquatic organisms. Penconazole accumulates in the soil; at the beginning of application, the disintegration period is 14 days, with frequent use up to 21 days.
Therefore, it is not recommended to carry out Topaz treatments on one garden plot for more than 3 years (Podgornaya M.E. 'Dynamics of topaz decomposition in garden agrocenoses.' Journal "Protection and Quarantine of Plants", No. 12, 2003.
Security measures. Gloves should be used when working with the drug. Avoid contact of the solution with eyes and skin. Eating, drinking and smoking is not permitted. After work, wash your hands and face thoroughly.
Recommended Dosages
According to the instructions for use of the drug Topaz, it can be used on almost all varieties of plants, however, treatments during the budding and flowering phase should be avoided. In addition, indoor flowers cannot be sprayed for prevention: they are treated only when there are obvious signs of the disease.
Average rates of fungicide consumption:
- At the first signs of powdery mildew on vegetable plants (cucumbers, tomatoes, etc.), 1.5 ml of the drug should be dissolved in 10 liters of liquid and four treatments should be carried out at an interval of two weeks. For a 10 m² area you will need about 1 liter of medicinal emulsion.
- To prevent rot and powdery mildew on fruit trees, dilute 3 ml of the drug in a bucket of water. The treatment is carried out twice - before and after flowering. Each mature tree requires at least 2 buckets of solution.
Flutryvit can be used for prevention
- According to the instructions for using Topaz fungicide for grapes, at the first signs of oidium damage, it is necessary to spray, making a solution of 3 ml of the drug and 10 liters of water. Preventive treatments are advisable after bud break and at the end of flowering. For 10 m² of soil, 1.5 liters of working fluid will be sufficient.
- To prevent and treat powdery mildew on fruit bushes, dissolve 2 ml of fungicide in a bucket of liquid and carry out 2-4 sprayings - after flowering and after harvesting. The consumption rate for each bush is 1-1.5 liters.
- To get rid of fungal diseases on garden flowers, you need to spray them three times with a solution of 2 ml of Topaz diluted with ten liters of water. To combat rust, the dosage of the drug should be doubled. The first treatment is carried out when signs of the disease are detected, the rest - at intervals of 15 days. Consumption of the finished solution is 1-1.5 liters per 10 m².
- For indoor plants, 2 ml of fungicide is dissolved in five liters of liquid. Spraying should only be done if there are obvious signs of the disease. To increase the effectiveness of the fungicide, all affected leaves should be removed first. As a rule, two treatments are enough to achieve a lasting result.
This is interesting: oidium.
Topaz CE is a very effective remedy that can quickly destroy pathogens and prevent their further spread. However, it should be remembered that the fungicide tends to accumulate in the soil, so it is not advisable to use it too often.
Reviews
Irina, Leningrad region:
I don't know a better remedy for damned powdery mildew than Topaz. In our area, this invasion is already difficult to treat; apparently, the fungus is mutating or has already become accustomed to the medications. Oxihom is also good, but Topaz is still more convenient and better, and, according to other roof owners, more efficient. I prefer it because it is less toxic.
Oleg, Tambov:
I grow cucumbers in large quantities (greenhouses, greenhouses, thickets). Somewhere from the second half of summer, powdery mildew is a frequent visitor, although it seems to follow all the rules of agricultural technology. I've been using Topaz for two years now, just a few sprays. The leaf is green again, the spots have disappeared, there are no plaques. Some treat before the disease to prevent it, but I believe that there is no need to feed vegetables with harmful substances in vain. We use it after illness, and the effect is good.
Topaz is a highly selective new generation fungicide used for the prevention and control of fungal diseases. Using the drug for vegetables and fruit trees, everyone can save plantings from death and preserve the harvest.

Instructions for use
On the day of spraying the plants, a working solution is prepared. The dose of fungicide depends, first of all, on the degree of infection of plants with mycosis, as well as on what stage of the growing season the crop is at. So, if the plant is at the initial stage of its growth and development, and the infectious background is low, then the minimum consumption rate of the drug should be used. With a high degree of mycosis infection, with full development of the leaf surface - the maximum norm.
To make the solution more effective, spraying must be carried out on a clear and windless day.
It is recommended to spray fruit trees and berry fields twice per season. The first time as a preventive measure before flowering, the second time after flowering. Vegetable crops and indoor plants are treated when signs of fungal infection are detected. At the same time, before starting treatment, it is recommended to remove all leaves infected with the fungus from the plants.
Advantages of the drug
- Can be used on many crops at risk of powdery mildew.
- Reduced number of treatments, flexibility in timing of application.
- Possibility of use in surface irrigation conditions.
- Systematic movement within the plant allows you to protect all parts susceptible to infection by the disease.
- No phytotoxicity.
- Suitable for inclusion in integrated plant protection programs.

Instructions for use
To effectively cure diseased crops, you must follow the instructions for use. It is better to carry out the spraying procedure outside at a time when there is no wind or rain, then the fungicide will be completely absorbed into the plant tissue and rid them of parasite spores.
It is not recommended to re-treat if it starts to rain after a few hours. Precipitation will not in any way affect the effectiveness of the product, which during this time has time to be absorbed and fulfill its purpose.
Subsequent treatment is carried out after 2 weeks. The drug cannot cope with advanced diseases, so repeated spraying will not help with a widespread fungal disease. Topaz is recommended only at the first signs of infection.
Treatment of grapes with Topaz
Grapes are often affected by powdery mildew, but this disease is called oidium.
The solution for the affected crop is diluted from two ampoules per 10 liters of water. For one grape bush, 1 liter of the resulting liquid is used. Spray the grapes in the direction of the wind.
The vines are treated 4 times with an interval of 20 days. Before the berry harvest begins, 20–30 days must pass from the date of the last treatment.
Fungicide for gooseberries
For preventive purposes against diseases and pests, this crop is also treated with Topaz Ke. One ampoule is diluted in 10 liters of water and the bush is sprayed with 1.5 liters of the resulting liquid.
The procedure is carried out 4 times per season with an interval of 2 weeks. The instructions for use provide the same proportions for currants with strawberries as with gooseberries.
Treatment of violets with Topaz
It is known that powdery mildew affects not only garden violets, but also indoor violets.
The disease initially looks like dust, which inexperienced gardeners do not attach much importance to. And later, the disease deforms more and more parts of the plant, acquiring powdery spots. This is possible at low temperatures that do not correspond to the recommended conditions for growing violets. To cure a flower, add one ampoule of the drug to 4 liters of water. The affected areas of the potted flower are evenly moistened with the freshly prepared liquid. If re-treatment is required, it is carried out after 2 weeks.
Processing cucumbers
Many summer residents who grow various varieties of cucumbers are already familiar with a common crop disease like powdery mildew. Basically, the disease destroys non-hybrid varieties of cucumbers, so it is necessary to regularly inspect the bushes for defective areas in order to prevent the spread of the disease and preserve the entire harvest.
One ampoule of Topaz is diluted in 10 liters of water. For 10 square meters, 1 liter of the resulting solution is allocated. Sometimes 0.5 liters of solution is enough for this area.
As you can see, for each type of culture, the instructions for use give different recommendations for diluting the medicinal liquid. In order not to harm the plants, you must strictly follow all the recommendations on the packaging.
Folk remedies instead of Topaz
It simply will not work to replace a systemic fungicide with folk remedies - Topaz penetrates into the plant tissue, and the principle of action of folk remedies is to cauterize the fungus on the surface. However, Topaz cannot be used when coloring berries, so you will have to look for something harmless.
Can be applied:
- baking soda 75 g + 5 drops of iodine per 10 liters of water;
- potassium permanganate (pink solution, the color is like when bathing children;
- potassium iodide 3-4 g/10 l;
- Metronidazole or Trichopolum 1 tablet per 1 liter;
- Furacilin 1 tablet per 1 liter;
- Potassium monophosphate 70 g/10 l.
Complex fungicides for grapes
Now, let's look at the best fungicides for treating grapes. These are relatively new drugs that have been used not so long ago, but have already gained great popularity among winegrowers.
Convertible Top
This is a combined remedy that allows you to simultaneously get rid of two grape diseases - oidium and mildew. In addition, this product, like biological insecticides, destroys harmful insects. The principle of action of the substance is the ability to create reserves of the active substance on the surface of the green mass. This protection is maintained even after precipitation.
Cabrio Tom is one of the few drugs that is highly effective against mass infection of bushes with mildew and oidium. It is used in the treatment of anthracnose and various types of spots.
Due to the long-term effect of action, there is no need for frequent treatments of plants, and accordingly, the degree of exposure to toxic substances on plants and their fruits is reduced.
Paracelsus
This is a contact-systemic fungicide that treats and eradicates any disease of grape bushes. In addition, this substance promotes the regeneration of affected tissues.
The principle of action of the drug is as follows: the active substance - flutriafol - disrupts the reproduction process and synthesis of the cell wall of the fungus. Vapors of a toxic substance enter the fungal cells, resulting in the process of poisoning pathogens.
Popular analogues of the drug Paracelsus are Scalpel, Impal, Medicine Man, Cornet. These are antimycotic agents with a similar spectrum of action.
Paracelsus fungicide has many advantages:
- creates protection for plants from re-infection for a period of 45 days;
- non-toxic;
- penetrates deeply into tissues, creating the maximum degree of protection for the entire plant;
- absolutely safe for the environment and humans;
- acts quickly and is rain resistant;
- It has a triple action - contact, systemic and fumigation.
Polychomus
A complex product that provides effective protection to the vineyard from infection by pathogenic microflora. The active components are copper oxychloride and polycarbocin, which together enhance the effect of the substance.
It is also important that the instructions for using the complex allow you to treat plants in any weather conditions. In addition, Polychom has an affordable price.
The fungicide is used only during the growing season of plants. In general, at least 4 treatments are necessary during the season. Such products as Revus, Polyram and Tilt have a similar effect.
Acrobat
Contact-systemic antifungal agent used for spraying vineyards. The active components of the substance - Dimethomorph and Mancozeb, provide a double barrier to pathogens, both from the inside and outside.
The substance is used in diluted form. The solution is prepared according to the instructions.
To ensure maximum protection of grapes from mildew, oidium and other fungal infections, fourfold treatment is carried out. The following drugs have a similar effect: Homecin and Horus.
Current questions about the fungicide "Topaz"
The official instructions for this fungicide do not provide for its use in indoor floriculture. However, many lovers of indoor floriculture have independently developed schemes for using this drug. They dilute 9 drops of emulsion concentrate in 1 liter of water and spray gloxinias, violets, monsteras, and streptocarpus with the resulting liquid.
However, when treating indoor plants, you need to take into account that “Topaz” has a chemical smell that is quite pronounced. Therefore, spraying should be carried out only on the balcony or open terrace. And, of course, we must not forget that this fungicide has a limited scope of action. This is not a universal drug.
Question No. 2. What analogues do the drug “Topaz” have? (click to expand)
Currently, this drug does not have complete analogues. Only Topaz is produced based on penconazole. Therefore, to protect plants from powdery mildew, only fungicides with other active ingredients can be used instead. The most commonly used drugs are “Skor” → how to use a fungicide, “Oxychom” → application reviews, “Tiovit Jet”.
Reviews from gardeners
Elena, 27 years old, Moscow region
I use Topaz fungicide to get rid of powdery mildew on gooseberries and currants. I carry out the treatment 2-3 times: in early spring, when the first leaves appear, during flowering and in the fall after harvesting the berries. The product is effective only if you treat the plants several times a season. An excellent product against fungal diseases on shrubs.
Valery, 48 years old, Perm
Two years ago, powdery mildew affected the gooseberries, so we were left completely without a harvest. Last year I decided to use chemicals to ensure that I could pick the berries from the bush. When used correctly, Topaz helps cope with the disease. In early spring, I treated the gooseberries twice with an interval of 10 days. I diluted the Topaz fungicide emulsion with water according to the instructions. During the season, no signs of disease appeared.
Ekaterina, 36 years old, Voronezh
Last year powdery mildew appeared on the roses. To fight the disease, I decided to purchase the drug Topaz. I treated the rose this morning. Although it rained during the day, the fungicide began to take effect. I watched the bushes for a week and did not find any new signs of the disease. After 10 days I repeated the spraying. Gradually the rose comes to its senses and produces new leaves.
