Topaz fungicide instructions for use, achieved effect

Classification and safety

Topaz belongs to the triazole class of fungicides, the active ingredients of which prevent the germination of spores.

Such means do not ensure the destruction of mycelium that has already grown in plant tissues; their task is to stop the further development of the fungus.

The working substance of Topaz is the organic compound penconazole, its concentration in the drug is 10% (100 g per liter).

The largest producer of Topaz is Swiss, a supplier of fungicides, herbicides, insecticides, growth stimulants, as well as seeds of vegetable, flower and field crops of international level.

In Russia, the company is represented by Syngenta LLC.

You can also buy other brands of Topaz fungicide on the Russian market:

• "Belreakhim", Belarus;
• "August", Russia;
• Green Belt, Russia.

Description

Drug Topaz

The drug Topaz is developed on the basis of penconazole, which automatically binds it to triazole. Derivatives of the latter, depending on the concentration and arrangement of nitrogen and carbon atoms in the compound, find use as antibiotics, antispasmodics and even cardiac stimulants. This definitely proves why researchers rely on triazole when developing quality fungicides.

The chemical composition of the Topaz fungicide cannot be taken away, but the mechanism of action of its inhibitor does not cause toxic harm to beneficial insects (for example, bees, ants), birds and catfish. Unfortunately, other inhabitants of reservoirs do not tolerate the drug well. But the antifungal effect of penconazole makes Topaz useful for combating many diseases caused by increased moisture and the subsequent development of mycelium:

• Powdery mildew;
• Downy mildew (peronosporosis);
• Mosaic;
• Rust;
• Gray rot;
• Oidium.

If oidium disease spoils grapes, rust damages gardening and berry trees and shrubs, then powdery mildew affects pumpkin crops, as well as tomatoes. In any case, after penetration into the spores of the plant, topaz moves through its vessels in an acropetal manner, i.e. according to height. This allows you to prevent infection in any area, even if it is about to form from an outlet.

On a note! Most pests, especially Lepidoptera, tend to lay eggs on wet leaves. Parasites absolutely love a pathogenic environment. Therefore, topaz also prevents the invasion of harmful insects from plant diseases, due to which the need to treat the crop with toxic and less toxic pesticides and insecticides, respectively, is reduced to zero

What the drug destroys, the effect achieved

Topaz is intended to combat powdery mildew, but also shows good results in the treatment of other diseases of vegetable, fruit and berry, ornamental and medicinal plants caused by fungi.

The use of a fungicide is justified against the following diseases:

• oidium;
• cladosporiosis;
• rust;
• net spot;
• fruit rot;
• cercosporellosis;
• purple spot;
• coccomycosis;
• scab;
• gray rot;
• septoria.

The drug is effective only at the initial stage of plant damage; in advanced cases it has little effect. But Topaz showed itself best as a prophylactic agent.

Purpose and application

The main purpose is highly effective control of powdery mildew on vegetable and fruit plants:

• cucumber and other vegetable crops in open and protected ground (powdery mildew);
• stone fruit and pome crops (powdery mildew, fruit rot);
• grapes (oidium);
• strawberries (powdery mildew);
• seedlings of berry crops (purple spotting, gray rot);
• currants and gooseberries (American powdery mildew);
• flowers (powdery mildew, rust), etc.

It is successfully used both in agricultural production and private farms.

External characteristic signs of powdery mildew on plants

Mechanism of action

Penconazole penetrates plant tissue and moves through the vessels along with nutritious juices. As the green mass grows, the substance continues to spread into young shoots, leaves and inflorescences.

That is, for the duration of the action of such drugs, even the shoots that grow after treatment are protected.

Penconazole stops the germination of spores into leaf blades and suppresses the development of mycelium, including the reproductive cells responsible for the formation of new spores.

Having lost the ability to reproduce, the mycelium gradually dies under the influence of the plant’s immunity.

That is why in cases of severe damage, Topaz is not effective.

The therapeutic effect of the fungicide is due to the ability of penconazole to suppress the production of sterols, including mycosterols, structural components of fungal cell walls.

With a lack of these substances, the formation of new mycelial hyphae and spore growth tubes is impossible.

Operating principle

Penconazole works best if powdery mildew on currants is noticed at an early stage of development. Once on the surface of the plant, Topaz is quickly “absorbed” into the tissue in a safe concentration, spreading to the entire above-ground part of the bush and its root system. It “gets ahead” of pathogen spores moving through the vascular system, providing currants with effective protection.

Topaz inhibits the process of synthesis of vital substances in the spores of the powdery mildew fungus that affects currants. The pathogen cannot develop and reproduce normally due to the lack of new spores germinating in the tissue. Currants, which are distinguished by their high overall endurance, cope with the “adult” fungus already present on the bush independently or with the help of biostimulants used by the gardener.

Important! Topaz does not remain on the leaves and shoots of currants in the form of a film, so the duration of the protective effect does not depend on the frequency and intensity of precipitation. The main thing is that there is no rain during the first 6-7 hours after treatment.

Toxicity

Topaz has been assigned the third class of danger to humans and bees. Such drugs are moderately toxic, but require certain safety precautions during their use.

In particular, due to possible harm to insects, spraying of the substance using aircraft is prohibited.

The fungicide poses a great danger to fish and other aquatic organisms, so Topaz should not be used in areas near any water bodies.

Penconazole accumulates in the soil because it is poorly washed out by water; according to its persistence in soil, it is assigned the second hazard class.

The disintegration period of the substance is 18 days, but regular use of the product increases this period to 21 days.

It is not recommended to use Topaz in garden plots for longer than 3 years.

Safety precautions

Fungicidal preparations require compliance with the following rules:

• when spraying, they work in protective clothing, a mask, and gloves;
• use separate containers, which are then disposed of or put away until further use;
• exclude contact with food;
• in case of accidental contact of Topaz with the skin, wash the skin with plenty of clean water;
• if the product or working solution gets on your face, thoroughly wash your eyes, skin, and rinse your mouth;
• in case of minor poisoning and penetration of the fungicide inside, take activated carbon, washing down the product with plenty of water. Gastric lavage helps, after which you must consult a doctor;
• used ampoules and suspension containers are disposed of.

Release forms

Penconazole is a blue crystalline powder. In its pure form, this substance is not soluble in water, so Topaz is sold only in the form of a liquid suspension. This is an emulsion concentrate (EC) and cannot be used without preparation.

Since the drug is approved for use on both farms and private farms, i.e., it is intended for treating large areas and small areas, there are several options for its packaging:

• 2 ml ampoules;
• hermetically sealed bags – 4 ml;
• bottles – up to 1 l;
• canisters – up to 5 l.

Treatment of currants in spring with Topaz

The best time to spray currant bushes with Topaz in spring is early morning or late evening. It is advisable that the weather be dry and windless. The solution should be sprayed as evenly as possible, in one layer. Currant bushes are not large in size, so problems with processing, as a rule, do not arise.

In one season, a maximum of four sprayings are carried out at intervals of two weeks.

Important! The approximate consumption rate is 10 liters per hundred square meters or 1.5-2 liters per currant bush.

Compatibility

Topaz can be mixed with other fungicides or insecticides if they have a neutral reaction. These do not include, for example, metal oxides - iron and copper sulfate.

The product can be combined with solutions of mineral fertilizers. The combination of foliar feeding and spraying against pathogens not only significantly saves time, but also maintains the strength of plants to protect against the harmful effects of pesticides.

The compatibility of Topaz with the growth stimulator Zircon and the following drugs has been tested:

• "Ridomil Gold" - for the treatment of Alternaria, late blight, downy mildew, anthracnose, mildew;
• “Chorus” – protects against clusterosporiasis, moniliosis, alternaria blight, complex of berry rots in grapes;
• “Topsin-M” – for fusarium, cercospora, net and dark brown spot;
• "Tiovit Jet" - against spider mites;
• “Aktara” - from aphids, Colorado potato beetles, leafhoppers, wireworms, apple and pear honey beetles, apple flower beetle;
• “Kinmiks” – removes thrips, leafhoppers, aphids, cabbage cutworms, white moths and moths, leaf rollers, copperheads, codling moths, flower beetles, cruciferous flea beetles.

When preparing a mixture with Topaz, the second pesticide is taken in the volume indicated for it in the instructions, without reducing the dose. The listed drugs contain active ingredients that do not react with penconazole.

Topaz is best combined with the fungicide Kuproksat. This is a product for protecting grapes, apple trees, tomatoes, beets, cucumbers from late blight, scab, mildew, clusterosporia, alternaria, moniliosis, and leaf curl. The active ingredient is tribasic copper sulfate.

Compatibility of Topaz fungicide with other products

Topaz fungicide has good contact with most pesticides and insecticides. It can be used in tank mixes.

For maximum effectiveness, Topaz fungicide is combined with products, taking into account the instructions for use for the drugs:

• Kuproksat (contains copper and is not recommended for plums);

• Topsin M (contains theophanate-methyl pesticide);

• Horus (contains cyprodinil).

Advice! When creating combined solutions, Topaz fungicide is poured in first.

Other characteristics

To use Topaz correctly, it is important to consider the following features:

Compatibility with other drugs

The compatibility of the Topaz chemical with other chemicals may not be recommended in the instructions for use, but for comprehensive prevention of various plant diseases this must be done regularly. To do this, the drug “Topaz” for plants can be mixed with such products as:

1. "Chorus", which is used for the prevention and treatment of Alternaria, fruit rot, clusterosporia, cocomyctosis.
2. "Topsin-M", which is used against scab, moniliosis, gray mold, anthracnose.
3. "Kinmiks" is a drug for controlling the larvae of agricultural pests.
4. "Kuprosat", which allows you to fight late blight and cercospora.

All of the above drugs are fungicides, but they differ from each other in the active substance. Thus, when combining drugs there is no need to reduce doses and they can be used in accordance with recommendations.

Instructions for use

To protect against diseases, plantings are sprayed with Topaz solution. It is important to correctly determine the required concentration of the substance, since a solution that is too weak is ineffective, and an overdose is dangerous.

Class 3 drugs are toxic enough to harm humans and plants.

Safety precautions during processing

Since the fungicide is poisonous to bees, spraying is carried out only in the evening, in calm weather. If the wind speed is more than 5 m/s, work should be postponed until another day.

You should not use Topaz if there is an apiary within a radius of 2-3 km; it is enough to lock your swarm in the hive for 72 hours after spraying.

Do not treat with Topaz a garden or vegetable plot that is located next to houses, buildings for livestock and poultry, or places where people walk.

Permissible minimum distances:

• residential building – 15 m;
• cowshed, chicken coop, stable – 50 m;
• pedestrian road – 50 m;
• ponds, playgrounds, recreation areas - 150 m.

The active ingredient of the fungicide can cause burns - do not allow the product to come into contact with the eyes, skin and mucous membranes.

Spray the product only while wearing clothes that cover your legs and arms, a hat or headscarf, waterproof shoes, gloves, and goggles.

To protect your respiratory tract, use a Petal-type respirator. In such equipment you can work with Topaz for no more than 6 hours in a row.

Do not smoke, drink or eat while spraying or preparing the solution.

Do not use food, drink or food containers to prepare the solution.

The prepared working fluid cannot be stored; it is necessary to dilute such a volume of the product that can be used at a time.

After finishing spraying, wash your hands and face with soap, preferably take a shower, wash protective clothing, and rinse the tank that contained the liquid.

Empty ampoules or canisters should be discarded and the drug should be kept out of the reach of children and animals, away from food and medications.

Spilled concentrate must be wiped off solid objects using an organic solvent.

In the area treated with Topaz, you cannot do gardening or gardening work for the first 7 days.

It is permissible to collect and eat fruits in rainy summers after 18 days or after 21 days if the weather was dry at that time.

Preparation of working solution

Since the drug is produced in the form of an emulsion, it is easy to dilute:

1. First, measure out the dose of concentrate, pour it into a container and add a small amount of water there.
2. Mix well and dilute with cold water to the required volume. It is advisable to use plastic utensils and a spoon.
3. After this, stir the product intensively for 3-5 minutes.

During processing, periodically shake the tank with the working fluid so that the active substance does not accumulate at the bottom. Use this solution within 7-8 hours after preparing it.

The standard volume of fungicide for preparing 10 liters of working fluid is 2 ml.

A solution of this concentration will be sufficient against most diseases, but to treat rust, 4 ml should be diluted in 10 liters of water.

Increasing the dosage to 3-4 ml is appropriate in case of severe damage, as well as for ornamental crops whose fruits are not eaten. Working fluid with a concentration of 4 ml/10 l may have an inhibitory effect on the growth of some plants.

Consumption rates

The amount of product required to treat the area is determined by the culture, disease, level of infection of the plantings, growth conditions (open or closed ground), age and phase of the growing season.

At the early stage of the disease, as at the beginning of growth, less working fluid is consumed than in advanced cases or with full development of the leaf cover.

To spray a short young tree you need about 2 liters of the prepared solution, and for an adult tree with a large crown it will take 5 liters.

When processing shrubs, they spend 1.5-2 liters, and hundreds of vegetables - about 5 liters.

Consumption rates for different crops are presented in Tables 1 and 2.

Table 1.

Table 2.

Preparation of working solution

Topaz working solution is prepared as follows:

• First, the required amount of the drug is mixed in a small amount of water. It is necessary to stir the resulting liquid for several minutes so that all of the liquid Topaz concentrate dissolves;
• then the rest of the liquid is added and stirring is done again;
• then the drug is poured into a sprayer and the plants are treated.

The prepared working fluid should be used in the first hours; the prepared solution cannot be stored. During treatment, the solution should be shaken periodically.

Important!

After completion of work, the remaining working solution of the Topaz drug is disposed of.

It is better to treat plants with Topaz solution in dry, windless weather from May to September. The interval between crop treatments should be observed, taking into account the type of plants, the degree of their damage, as well as the type of pathogens.

The maximum dosage is used when there is a high degree of disease damage; for preventive spraying, the dosage of the drug is much lower.

Topaz is more effective as a prophylactic or in the fight against fungal diseases in the early stages. If the disease is severely advanced, it is better to use stronger fungicides.

Features of use for other crops and plants

Treatment for pests and diseases with any drug will differ depending on the crop being treated.

Topaz consumption rates were discussed above; now you need to determine when and how to spray.

For cucumbers

When using Topaz to protect cucumbers, it is important to make sure that you do not have to harvest the crop in the near future.

The fruits of this crop grow quickly, and if you keep them on the vines, the taste of the vegetables may deteriorate.

It is best to spray cucumbers at the beginning of the growing season for prevention.

1. The first treatment is done no earlier than the third leaf on the main vine has fully developed.
2. The second spraying is recommended after 10-14 days.

To prepare the working fluid, dissolve 2.5-3 ml of concentrate in 10 liters of water. According to the same scheme, Topaz is also used to treat melons and zucchini.

For tomatoes

Most tomato diseases appear long before the fruits become ripe; in addition, in this case, you can keep the crop on the bush for several extra days without affecting its quality.

Therefore, the treatment of tomatoes with Topaz is carried out at the first symptoms of the appearance of fungi. To do this, dissolve 5 ml of emulsion in 10 liters of water.

It is permissible to spray tomatoes for the first time this season in the fourth leaf phase on the main shoot.

In total, two treatments can be done with a break of 10 days, the last one no later than 21 days before harvesting the fruits.

Similarly, a fungicide is used to combat diseases of eggplants and sweet peppers.

The only difference is that eggplants begin to be sprayed no earlier than the first inflorescence appears on the bush.

For strawberries

The first treatment of strawberries is done at the beginning of the period of mustache formation, and the second – after the berries are harvested.

You should wait at least 10 days between procedures. Dissolve 2.5-3 ml of concentrate in 10 liters of water and spray one hundred square meters of strawberry planting with this liquid.

Carry out preventive treatment in the last ten days of May or early June.

For grapes

The risks to the crop when grapes are infected with oidium are great; preventive measures should not be neglected.

To do this, treat the vine before the flowers form; you can do this immediately after the buds open.

It is advisable to repeat spraying in the fall. The recommended concentration of the working solution is 2 ml of emulsion per 10 liters of water.

If symptoms of oidium or another fungal disease have already appeared, spray with Topaz four times.

Dilute 3-4 ml of fungicide in 10 liters of water and treat one hundred square meters of vineyard. A bucket of solution is enough if the vine is pruned correctly, otherwise you need to increase the volume of working fluid consumed.

There should be 2 weeks between treatments if it rains, or 3 weeks if there was a drought during this period.

Spraying should not be carried out less than 3 weeks before picking berries, or during flowering.

It is permissible to treat the vine with Topaz at the beginning of the formation of buds, and the next time - after the ovaries appear.

For prevention, the drug can be used after the first leaves appear.

If you want to get completely organic grapes, spray them no later than a month before harvesting. During this period, the substance decomposes to 0.001%.

For roses

Treat rose bushes at the first signs of disease or for prevention during the formation of buds. It is not advisable to use a fungicide during the flowering period.

Roses of varieties that bloom several times per season must be sprayed after each wave of flowers.

For 10 liters of solution, use 5 ml of concentrate. In case of severe damage, as well as for roses in a greenhouse, where the fungus spreads very quickly, the dose of the emulsion is increased to 7-10 ml.

In one summer, 3 treatments are allowed, the pause between which should be at least 20-25 days.

Other flowers in the flower beds

Powdery mildew and rust especially often affect several types of ornamental plants.

Prevention with Topaz is recommended for protection:

• peonies;
• carnation;
• chrysanthemums;
• clematis;
• violets;
• snapdragon;
• irises

Against powdery mildew, dilute 2 ml of the drug in 10 liters of water, to get rid of rust - 4 ml.

The concentration of the working fluid can be increased, but if vegetables or berry bushes grow next to the flowerbed, a strong solution cannot be used.

If the disease appears during the flowering period, treatment is carried out only in the evening, when the petals close.

Topaz solution can leave stains on flowers, and in the case of delicate crops such as petunia, also on leaves.

4 sprayings per summer are allowed with pauses of 7-14 days.

For indoor plants

To treat specimens located in residential premises, it is better not to use Topaz. But in the summer, you can take the flowers outside or onto the balcony and spray them there.

You can return it to the room only 4 hours after applying the fungicide.

For domestic flowers (violets, ficus, orchids), prepare a weak solution - 1 ml per 10 liters of water for plants with a large crown and 0.5 ml for miniature specimens.

3 treatments are allowed, but there must be a two-week pause between them.

Topaz is the best remedy for powdery mildew

The drug Topaz: reviews of use

Ira, 54 years old, Leningrad region: Powdery mildew regularly appears on plants in my garden plot. I used different means, but the fungus quickly gets used to them and no longer dies. I saved my garden only with Topaz - I carried out a couple of treatments, and the powdery mildew disappeared. I can say that Oksikhom also turned out to be quite effective, but Topaz is cheaper and less toxic.

Elena, 46 years old, Tambov region: I am engaged in growing cucumbers in greenhouses and in garden beds for sale. And since the second half of summer, my cucumber beds have been affected by powdery mildew for many seasons, despite following all the rules of care. The season before last, a neighbor in a dacha cooperative advised using Topaz to combat this fungal disease. As soon as I noticed the appearance of the disease, I carried out the first spraying, and a couple of weeks later - the second. And the powdery mildew disappeared. Now I will do this regularly - treat cucumbers with Topaz when this disease appears.

The fungicidal drug Topaz is one of the best preventive and therapeutic agents against a number of fungal diseases on garden, vegetable and ornamental plants.

It is easy to dilute and easy to use, but fungi quickly get used to this product, so after a couple of treatments the drug has to be replaced with other fungicides that are also effective against these pathogens.

For fruit trees

Powdery mildew is an unpleasant guest in the garden, which can be difficult to get rid of, as are fruit rots, which are sometimes only discovered during storage of the harvest.

Therefore, it is important to carry out preventive treatment of trees.

Topaz is used to treat and protect apple, pear, cherry, and peach trees.

2-4 preventive sprayings per season are allowed:

• after swelling of the kidneys;
• after flowering;
• after the leaves fall.

If fruit trees are already sick, treatments are carried out at intervals of 21 days.

In case of frequent rains, the period of protective action is reduced, so spraying can be repeated after 14 days.

In total, you can do 3-4 procedures, excluding cherries - no more than 2 times. To prepare a working solution, you need to dilute 3-4 ml in 10 liters of water.

When to spray currants with Topaz in spring

Topaz on currants manifests itself best at the early stage of disease development. Therefore, it is recommended to regularly inspect the bushes and apply a fungicide at the first suspicious symptoms.

For prevention, currants are treated with Topaz in the spring, at the very beginning of the active growing season, when sap flow is just beginning. Sometimes gardeners practice 2-3 spring sprayings with an interval of at least two weeks, slightly reducing the concentration of Topaz and ending the prevention by the time the buds form.

When determining the timing of processing, you can focus on the appearance of the buds, resembling “green cones”

If fungal diseases are a typical phenomenon in the garden, spraying is repeated 1-2 more times, about a month after harvesting. Or the procedure is postponed until the fall, timing it so that at least 5-6 weeks remain before the first frost.

For shrubs

Like trees, it is recommended to treat berry bushes with fungicides without waiting for fungal infections to appear. Prevention is carried out according to a similar scheme.

In case of disease, spraying is repeated every 2-3 weeks, but no more than 4 procedures per summer.

The use of Topaz is permitted during the budding phase or after the formation of ovaries, but not during flowering.

For currants, gooseberries, raspberries, blackberries, dissolve 2-3 ml of fungicide in 10 liters of water.

Currants are especially vulnerable to powdery mildew - carefully treat its crown, using up to 2 liters of working fluid per bush.

If the shrub grows near beds with vegetable crops, Topaz cannot be used to protect it for more than 2 years.

Penconazole accumulates in the soil and can enter neighboring plants through the roots.

Pros and cons of using Topaz for currants

Summer residents actively use Topaz to protect currants and other plantings from fungal diseases, taking into account its undoubted advantages:

1. Versatility - suitability for processing not only currants, but also any other garden crops grown in open ground and in a greenhouse.
2. Systematicity - Topaz is used to protect against fungi and prevent infection.
3. "Neutral" for plants. Topaz does not affect the growth and development of currants, the volume and quality of the harvest, or the taste of the berries.
4. Quick onset of action after treatment.
5. Long-lasting effect regardless of weather conditions. As a result, there is economical consumption of the drug and the ability to get by with a minimum number of treatments.
6. Admissibility of mixing with other fungicides, insecticides and pesticides.

Topaz also has certain disadvantages:

1. It is a chemical, so it is not suitable for organic gardeners.
2. It is safe only if Topaz is diluted for spraying currants, observing the dosage of the fungicide and waiting the required time before picking the berries.
3. Topaz demonstrates maximum effectiveness at the early stage of disease development. When time is lost and the process of infection of currants has gone very far, it can turn out to be almost useless.
4. Over the course of three seasons, pathogens develop resistance, so Topaz cannot be used constantly.
5. It is prohibited to process currants if they are located near ponds and apiaries (the fungicide is highly toxic to fish and bees).

Important! Treatment of currants against diseases with Topaz can be carried out not only in the spring, but also during almost the entire active growing season, with the exception of three weeks before picking berries in dry weather or two in frequent rains.

The safety of Topaz for currants, human health and the environment is guaranteed only if the manufacturer's instructions are followed.

Advantages and disadvantages of Topaz

Many gardeners and gardeners avoid using “chemicals” on their plots. But in some cases, lack of treatment leads to significantly more severe consequences for the crop than spraying with a pesticide.

Topaz is one of the mildest but most effective chemicals. However, its use is not always justified. In each case, it is necessary to weigh the advantages and possible harms of using a fungicide.

Among the advantages of Topaz it is worth noting:

• effectiveness against several diseases;
• the ability to process most garden and vegetable crops;
• speed of penetration into tissue;
• long lasting protection;
• moderate toxicity;
• harmless to plants;
• lack of film on the leaves;
• few weather restrictions;
• good compatibility with many pesticides and fertilizers;
• Can be used both in greenhouses and in open ground;
• low cost in comparison with analogues;
• economical consumption;
• long shelf life.

The drug also has several disadvantages:

• effectiveness only at the initial stage of the disease;
• restriction on use near bodies of water;
• impossibility of morning spraying;
• prohibition to use the product for more than 3 years in one area;
• ability to accumulate in soil;
• action against a limited number of fungal diseases;
• danger to plantings if the dosage is exceeded;
• long waiting period before harvesting, especially in hot weather;
• the need to comply with safety precautions.

Description and properties of Topaz fungicide

This is a hazard class 3 drug; it belongs to systemic drugs from the triazole group.

The chemical Topaz disrupts the process of sterol synthesis in pathogenic fungi, as a result of which they die.

Topaz can also be used for preventive purposes - after treatment, the drug penetrates into plant cells and prevents the development of fungus that gets inside.

On a note!

The active ingredient in Topaz is penconazole at a dosage of 100 g/l (or 10% of the total composition of the drug).

Photo of the drug Topaz

This chemical only affects pathogens and is not suitable for pest control because it is not an insecticide or acaricide.

Topaz effectively protects plants and fights the following diseases:

• powdery mildew;
• rust on foliage;
• gray mold;
• purple spotting;
• oidium;
• coccomycosis.

First aid

Despite the moderate toxicity of Topaz, if safety precautions are violated, the substance can cause great harm to human health.

In such cases, immediate action should be taken:

• contact with skin - collect the substance, avoiding rubbing, with a piece of cotton wool or cloth, preferably soaked in alcohol, then wash the affected area with soap and water;
• contact with eyes - rinse with plenty of running water, but the stream should be soft;
• inhalation - remove the person to fresh air or a well-ventilated room;
• ingestion - rinse your mouth, drink 3-4 glasses of water with activated charcoal (1 tablet per 1 kg of body weight), induce vomiting, drink water with charcoal again, seek medical help.

If any unexpected changes in your condition occur, you should stop working and contact a medical facility.

Is it worth using: reviews from gardeners

Do you think Topaz fungicide is an effective remedy?

Of course! Not really

According to various Internet portals, Topaz is actively used by many gardeners, and the product regularly receives high user ratings (4.4-4.5 points out of 5).

A year ago I began to actively grow violets, they grew quickly and confidently, and were pleasing to the eye. But in the middle of summer some dust appeared on the leaves. At first I didn’t think about the fungus at all, but it turned out to be powdery mildew, as they later suggested on the forum. I bought the first product I came across. Luckily for me it turned out to be “Topaz”. This is an excellent drug that costs a penny, but helps for the whole season. I carried out one treatment and a second after a couple of weeks - the dust disappeared completely. And even this season I didn’t attack the plants again - I haven’t treated them yet, but I’ve already prepared several ampoules.

Pirogova Lyudmila Vladimirovna

When our currants were covered with powdery mildew, a neighbor came and said, dig them up and burn them. I finally decided to try to process it with something. I read several reviews and bought Topaz: it’s inexpensive, 28 rubles per ampoule. I treated it a couple of times in July, using a bucket per bush, generously and without sparing it. The effect did not come immediately, but only after 2 years. Of course, during this time many would have already thrown away the currants, but it’s not so easy to plant new bushes. So I definitely recommend it, especially for such pennies!

Topaz is quite a decent product, our domestic fungicide. I use it only for prevention, purely according to the instructions. My neighbors periodically experience rust on their cucumbers, but I haven’t had this happen at all. That's all I can say.

I decided to take a risk and grow the capricious rose Avolanche - anyone who has encountered this will understand. I did everything correctly, and suddenly there was dust on the leaves, which meant powdery mildew. I’m used to fighting using traditional methods, but a friend recommended Topaz. I treated it like this: 1 ampoule per 5 liters of water, 2 times with an interval of 10 days. Gradually, the rose began to recover - true, the old branches bent, but new shoots began to appear. I'm waiting for the result

I came across the Topaz fungicide by accident. It’s just that rust settled on the gooseberries about 5 years ago, and urgent measures had to be taken, folk remedies no longer helped. Somehow I immediately liked Topaz and helped very well in my time. We also tried other means, but for some reason they did not give an effect. Perhaps the plants have already become accustomed to a certain regime, so I don’t plan to change anything yet.

Fungicide "Topaz" has a number of tangible advantages. This is a fairly effective remedy that can be used alone or in mixtures with other drugs. It is better to carry out treatment at the beginning of the season for prevention. During spraying, mandatory safety precautions should be observed, especially for persons with diseases of the respiratory and cardiovascular systems.

Reviews

Below we suggest that you read the reviews of people who have used Topaz on their plots.

Sofia, Kirov

For the first time I used “Topaz” as a replacement for the drug “Profit Gold” to save phalaenopsis.

Those who are fond of orchids know how terrible the quality of these flowers is in stores.

If left untreated, 100% of purchased plants rot. I work with flowers in the bathroom, the main thing is to wash it thoroughly afterwards.

It’s more convenient for me to take Topaz in bottles or canisters, because the remainder in the ampoule has to be thrown away.

I dilute the usual dose of the substance for indoor flowers not in 10, but in 2.5 liters. I soak the roots in fungicide (I cut off the rotten ones before doing this), let them dry and replant the orchid.

Topaz was used to save not only deeply flooded flowers, but also frost-bitten flowers.

Leonid, Kursk region

I barely got rid of powdery mildew on gooseberries, now I do preventive maintenance every year.

I have been processing it with Topaz for the last two years. Two sprays are enough, the first time as soon as the buds open, and then after another 7-10 days.

I know that some people in our village completely cut down their gooseberries because of powdery mildew, but this year I had a couple of dozen diseased berries out of 10 bushes.

And even they were not seriously affected, there were small spots.

Characteristics of the pest

The disease occurs especially often if the bush grows close to sedge or coniferous trees. It is important to be able to recognize the disease in a timely manner in order to begin the fight against the pathology before it causes significant harm to the currants.

When to expect the first manifestations

Glass rust may be asymptomatic in the early stages of the lesion. The gardener collects the harvest, prepares the bush for the winter, but still does not detect the first signs of the disease. This is not scary, since the pathology in this case will not cause severe damage to the currants. Find out about the white coating on currant leaves at this link.

Yellow pads on the leaves are the first sign of the disease.

However, in early spring the disease begins to actively develop. The first signs of the pest can be detected in early summer. From this moment you should begin to fight the fungus.

Symptoms and signs of damage

On the part of the plant where goblet rust occurs, orange or yellow spots appear. Defects on the leaves are especially noticeable - spots of a rich shade can be seen on top. There are black dots on the defects. The disease also affects the lower part of the leaf. Here the pathology manifests itself as yellow pads. After some time they take the shape of glasses. This is where the name of the parasite comes from.

Consequences

Goblet rust affects not only those parts of the plants on which the fungus progresses, but also the entire bush. As the disease progresses, the leaves become deformed. If the disease affects the branches of the bush, the leaves die and fall off.

Goblet rust also spreads to fruits. As a result, the berries take on an irregular shape. In addition, fetal development stops.

This means that the absence of timely measures aimed at getting rid of parsitis leads to a lack of currant harvest, loss of the plant’s frost resistance and death of the bush. The use of special drugs that destroy the pathogen will help to avoid such consequences. This article will tell you about the bud mite on currants.

Area of ​​use

The fungicide, based on the instructions for use, has a wide spectrum of action. The rate of spread is high, which gives the plant quick relief from damage:

• septoria and powdery mildew;
• purple spot and fruit rot;
• scab and rust;
• gray rot and oidium.

These diseases are more dangerous for roses, carnations, potted or garden plants. As for oidium, the disease occurs on grapes, in every third vineyard. And rot loves to settle on peaches. Topaz will also be beneficial for conifers.

Although these diseases are not often encountered on them. It is enough to completely cultivate the land holdings and forget about problems for a long period of time. Not afraid of rain, moisture. It is acceptable to spray fungicide at any time of the day.

Need to know! Despite the permission to use Topaz at any time, in any weather, experienced gardeners claim that spraying will be more beneficial when applied to the plant in the early hours. It is advisable to do the procedure in calm weather, but not sunny.

Fighting methods

You can fight goblet rust using various methods. This allows gardeners to choose the most suitable option.

Treatment with drugs

There are several chemical preparations that help get rid of glass rust in a short time. Before using any product, it is necessary to prepare the plant for treatment. To do this, it is recommended to perform the following procedures:

• cut off the affected parts of the currant from the bush;
• burn diseased leaves and branches to stop the spread of the fungus; if this is not done, the affected parts of the bush will settle in the ground, which will lead to re-disease of the plant;
• drain the soil to remove excess moisture.

Only after preparing the plant can the currants be treated with chemical preparations for goblet rust.

Previkur

It is a systemic fungicide with a broad spectrum of action. The product is used to combat goblet rust on currants and root rot. Previkur has protective properties, stimulates plant growth, and has a positive effect on the immune system.

To prepare a medicinal solution, you will need the following ingredients:

1. Previkur – 15 ml.
2. Water – 10 l.

Dissolve the drug in water. First take Previkur, add a little water, stir thoroughly. Gradually pour in all the liquid. Use the resulting solution to spray the bush.

Score

This is a contact, systemic fungicide intended for the prevention and treatment of various diseases of garden and indoor plants. A distinctive feature of the product is that it can be used at any stage of growth, flowering, and fruiting of currants. The main active component of Skor is difenoconazole, which belongs to the chemical class of triazoles. The product is recommended for use at an early stage of pathology development.

The drug is not used in its pure form. It is diluted in water. It is recommended to prepare the solution immediately before use. To prepare the product, dilute 2 ml of the product in 5 liters of water. Treat the currants with the resulting mixture.

Fitosporin

This is a new generation microbiological preparation. Recommended for use in the treatment of all types of fungal and bacterial plant pathologies. Product release forms:

• powder;
• liquid;
• paste.

The main advantage of Fitosporin is the possibility of use at any stage of flowering and fruiting of currants. As the manufacturer assures, the product will not harm either the berries or human health, even if the product is used on the day of harvest.

To prepare a solution for goblet rust, dissolve 5 grams of the product in 10 liters of water. Spray the currants with the resulting product.

The disadvantage of the drug is that the main active component dies under the influence of ultraviolet radiation. For this reason, it is recommended to use Fitosporin only in cloudy weather in the evening.

Topaz

This is a fungicide that prevents the appearance and helps destroy fungus on plants, including goblet rust. Topaz is an effective and safe remedy recommended for combating the disease. The main active element of the product is penconazole. The substance stops the reproduction of the fungus by stopping the germination of its spores.

One of the advantages of the product is its rapid absorption. This allows you to use Topaz even in rainy weather. The effectiveness of the product does not depend on temperatures. Even in hot weather the procedure will give a positive result.

To get rid of goblet rust, dissolve 4 ml of Topaz in 10 liters of water. Treat the plant with the resulting product.

Bordeaux mixture

This is one of the most effective remedies in the fight against goblet rust on currants. To prepare the solution you will need:

• copper sulfate – 100 g;
• calcium hydroxide – 100 g;
• water – 10 liters.

Dissolve both drugs in the specified amount of water. Use the resulting solution to spray the bush. It is recommended to perform the procedure three times during bud break. The interval between treatments should be at least three weeks.

Copper sulfate

This product can be used to combat fungal pathologies of plants and as a top dressing. The product promotes the destruction of pests (glassworm, aphids, scale insects), currant growth, and rapid fruit ripening. Read about folk remedies for aphids on currants here.

A solution prepared from copper sulfate is recommended for use before currant buds open. If the product is used later, the plant will receive a chemical burn. This will lead to the death of the currants. The drug can be used after the leaves have fallen.

To prepare the solution you will need the following components:

• copper sulfate – 100 g;
• water – 10 l.

The product should be prepared as follows: place copper sulfate in a container, add a liter of hot water. Stir the product thoroughly. Add 9 liters of hot water. Stir the solution again and filter the product. Cool the preparation and use it to spray currants.

Cuproxat

This is a fungicide designed to combat fungal plant pathologies, including currant goblet rust. One of the main active components of Kuproxat is copper. The product is moisture resistant, so it can be used even in rainy weather.

The drug destroys the pest upon direct contact. The substance penetrates the cells of the parasite that causes the disease, as a result of which the pathogen dies.

To prepare the product, shake the container with Kuproxat thoroughly. After this, measure out 50 ml of the drug, dissolve it in 10 liters of water. After this, treat the bushes with the resulting product.

Folk remedies

Folk remedies have proven their effectiveness in the fight against the disease. Such drugs do not give instant results, but they do not contain harmful chemical compounds.

Soda solution

To prepare this product, take:

• soda – 2 large spoons;
• liquid soap - 3 large spoons;
• hot water – 5 liters.

Dissolve baking soda and liquid soap in water. Pour the resulting product onto the plant. It is recommended to carry out the procedure many times. Read about processing currants with soda.

Manure

Another product that helps get rid of the disease is mullein. A solution should be made from manure to spray the plant. To prepare the product you will need the following components:

• manure - 1/3 of a ten-liter bucket;
• water – remaining volume.

Place manure in a bucket. Add water to the top. Place the mixture in a place where there is no access to sunlight. Leave the solution for three days. Stir the preparation during this entire time. After this, filter the product and dilute it with water in a ratio of 1:10. Treat the currants with the resulting mixture. Read about horse manure as a fertilizer here.

Dairy products

To get rid of fungus, you can use any natural fermented milk product. This can be kefir, yogurt, whey or simple sour milk. The mixture for goblet rust is prepared from the following components:

• fermented milk product – 1 part;
• warm water – 10 parts.

Combine both products and mix. Pour the resulting solution onto the currants. It is recommended to perform the procedure in the evening in cloudy weather.

Tobacco dust

Tobacco is one of the most effective products in the fight against glass rust. The fact is that the fungus does not tolerate this remedy.

To get rid of a pest using tobacco, you need to prepare a drug from the following components:

• tobacco dust – 200 g;
• hot water – 2-3 liters.

Tobacco dust from pests and diseases should be placed in a container and water added. Leave the drug to infuse for three days. After this, filter the solution and use a bush treatment product.

Garlic

Glass rust also does not tolerate garlic. For this reason, gardeners often use this product to control the pest. To prepare the garlic solution you will need the following components:

• peeled garlic cloves – 1 cup;
• hot water – 2-3 liters.

Combine both products and leave to infuse for three days. Then filter the solution and use it to spray the plant.

Prepare the products according to the recipes indicated above. Filter both solutions and pour into a 10-liter bucket. Place a large spoonful of liquid soap and a small spoonful of ground pepper into the container. You can use red or black product. Leave the solution to infuse for another day. After this time, filter the preparation. Use the product to treat the bush before the flowers begin to bloom. Read about ammonia against aphids and other pests in this material.

A good result can be achieved if you use garlic and tobacco at the same time.

Agrotechnical measures

To prevent glass rust from disturbing currants, you can use agrotechnical measures to combat the pest:

• get rid of sedge within a radius of 0.5 km from the site;
• do not allow excessive moisture in the soil under the bush;
• Choose currant varieties for growing that are immune to fungal diseases.

Safety precautions when working with the drug, waiting period

When working with chemicals of any origin, you should take precautions and avoid contact of the chemical with the skin. The drug is not fatal to humans, but safety precautions have not been canceled.

The following points should be followed:

• Use the container only for one-time use, then throw it away, or better yet, bury it.
• When the substance evaporates, it releases harmful toxins; you should use a respirator.
• If the solution gets on exposed skin, immediately rinse the area with running water.
• If vapor poisoning occurs, it is important to immediately drink activated carbon and half a liter of water. If the fungicide accidentally enters the human digestive system, you need to rinse the stomach.
• During treatment, it is prohibited to smoke, drink or eat nearby, as vapors can be absorbed into food and liquid.
• Store the substance in an isolated, dark room, away from children, medications and food.

By following precautions, the procedure will proceed without difficulty and without harm to health.

How to use Topaz fungicide for currants

Currants are susceptible to attack by powdery mildew. The disease is manifested by the formation of a white coating on berries, foliage and shoots. Initially, the plaque affects the lower branches and then spreads upward.

To prepare the solution, you need to follow the proportion: add three milligrams of fungicide to fifteen liters of water. For 1 currant bush, one and a half liters of diluted substance is used.

The solution is used as a preventive measure during the formation of inflorescences and after the flowers have dropped. For treatment, treatment is carried out when the first symptoms of infection are detected.

The procedure can be performed no more than four times per year. You should not carry out the treatment a month before harvesting the fruits.

The same scheme applies to raspberries, gooseberries, blackberries and strawberries.

What are the advantages of Topaz treatment?

Among chemical preparations you can find many similar products, however, Topaz is the most productive and effective among them.

The drug has a number of positive aspects:

• Unlike other substances, it has a long period of action on fungal spores. This allows spraying to be carried out less frequently, resulting in less stress on the soil and plants.
• Thanks to the instant absorption of the solution, the elimination of the fungus occurs within a few hours after the procedure.
• The concentration of the solution is sufficient for one ampoule or sachet to last for a whole season.
• The drug has a wide range of applications and is used for all cultivated and agricultural plants.
• The chemical is slightly toxic, even if the product gets on the fruits, they are completely safe for consumption.
• Has good compatibility with other chemicals, which improves efficiency.

Thanks to these advantages, the popularity of Topaz is several times higher than the demand for other similar substances.

Time to treat shrubs

It is easier to prevent any disease than to fight it. This also applies to glass rust. It is recommended to process currants before the disease occurs.

Spraying the plant is carried out in several stages:

• Perform the first treatment before the bush begins to flower, when the leaves begin to bloom;
• Spray again after the flowers begin to bloom;
• Carry out the third treatment after the currants have finished flowering.

If the disease has managed to spread throughout the plant, it is recommended to perform a fourth treatment of the bush with the drug. This should be done 10 days after the third procedure.

Resistant varieties of currants to goblet rust

There are varieties of currants that have good immunity to various diseases, including goblet rust. These include the following varieties:

1. Black veil.
2. Katyusha.
3. Belarusian sweet.
4. Grace.
5. Semiramis.

These are currant hybrids that are resistant to any pathologies. There are other plant varieties that are not afraid of fungus. If, despite good immunity, glass rust appears on the currant, then you can fight the disease with all the means given above. The currant-gooseberry hybrid Yoshta has good resistance to disease infection.
