Strobi: fungicide, instructions for use for grapes


Instructions for use

The instructions for use are quite clear and accessible to gardeners, both more experienced and those who are just starting to carry out their activities in the fight against fungal diseases.
Since “Strobe” is most often used to control pests that are located on grapes, you should find the appropriate section in the instructions so that the control is more effective in any conditions. The drug allows you not only to get rid of diseases, but also from other characteristic ailments to which grapes, vines and the berries themselves are susceptible. In addition, this drug is ideal for treating the root part, since it fights cancerous diseases of shoots, powdery mildew and scab. In order to obtain a solution in the correct concentration, it is necessary to dissolve Strobi in an amount of 5 grams per 10 liters of water. This concentration and quantity will be enough to treat the area where the grapes are located. Also, the treatment can be repeated regularly, throughout the entire flowering and fruiting season, until late autumn. The drug does not accumulate in the soil, but is very stable, even during the rainy season. This is its peculiarity and, most importantly, the safety of the resulting harvest for human life and health.

Not only parts such as the trunk, leaves and berries should be sprayed and treated - we must not forget about the root soil zone, since many fungi, parasites and diseases are often concentrated there, so it is extremely important to take this aspect into account when processing the area. In the ground, "Strobe" and its components decompose extremely quickly, without ever getting into the deep layers where the components can usually be stored

In water, Strobi decomposes to an acidic state and is not a dangerous chemical for groundwater. As we can see, new generation drugs in general have many advantages and are safe for the future harvest and for the human body.

Proper fight against fungus

Cabrio Top for grapes - fungicide, instructions

Adhering to all the rules for treating the fungicide with strobi, it will not be possible to completely cure the affected plant. If treatment was carried out 3 times last season, the volume of the lesion will be reduced by 50-75%. Fungal mycelia are not completely destroyed. Over time, the fungicide degrades. After this, the fungal pathogens that survived begin to develop and multiply again. To destroy young fungal seedlings, after 1 week you need to use a fungicide of a different class in minimal doses. This could be a quadris, cabriotop, thiovit jet, etc.

Another important rule in the fight against fungal diseases is the treatment of harvest soil with a preparation. This is the most optimal time for the introduction of harmful fungus. At this stage, additional protection of the plant is required. By this time, beneficial mushrooms have already produced spores and the drug will not harm them in any way, but will destroy pathogens.


Proper fight against fungus

Note! The most effective way to use strobe fungicide is by spraying. The drug has a low evaporation rate. This property promotes the formation of a gas shell around the plant and provides a long-lasting effect.

Fungicides for grapes


All modern therapeutic agents are divided into three large groups according to their principle of action:

  1. Contact.
  2. System.
  3. Complex.

Each tool has its own working algorithm. The effectiveness of the fungicide depends on the time of the growing season of the grape bush and the stage of a particular disease. If the disease has not yet affected the grapes, then some means are used; if infected foci appear, others are used.

Contact


Drugs in this group should be used as prophylaxis, since they are not able to fight an already existing disease. Contact fungicides reliably protect healthy plants during the rampage of infection in the garden area. The main advantage of contact agents is that plants do not develop immunity to them, and therefore useful spraying can be done several (3-6 times) per season. The disadvantages of such fungicides include a short period of action - they protect plants for about 10-12 days, then you have to resort to treating the plantings again. In addition, plants are sprayed again immediately after rain, since precipitation easily washes the product off the leaves.

The principle of action of contact preparations is such that their active substances do not penetrate into the plant, but create a surface protective film through which neither fungi, nor viruses, nor bacteria can penetrate. Due to the fact that the entire mass remains on the surface of the plant, the poisons included in this group are also called local. Treatment must be thorough, because if at least one untreated area remains, the infection will immediately “take advantage of the situation” and get inside the stem. Absolutely all above-ground parts of plants are sprayed - stems, vines, leaves, trunks.

Treatment with fungicides begins as early as possible, usually at the very beginning of the season, even before the infection appears in the garden. Thorough spraying of the grapes is carried out until the buds swell. During flowering, treatment with copper-containing solutions is not carried out, since this element can accumulate in different parts of the plant.

Attention! Contact agents are preventive. They do not treat the plant, but protect it from infection.

System


If the infection has already entered the plant, then systemic drugs are used in treatment. Their active substance freely penetrates into plant tissues, and from there it affects the pathogen. The active substance begins to fight the pathogen immediately as soon as it gets inside and reaches the source. The remedy blocks the ability of the fungus to reproduce - the pathogen stops growing and then dies completely. Systemic fungicides can be used at all stages of plant development and at all stages of disease development. Their validity period is practically independent of weather conditions, since they are not washed off by precipitation and do not evaporate in the sun.

But it depends on the immunity of the fungus and the speed of its reproduction. Usually the therapeutic effect lasts for 2-3 weeks, then the treatment should be repeated. However, you should not overuse aggressive chemicals, otherwise it can lead to oppression of the plant. The weaknesses of systemic agents include the rapid adaptation of infectious agents to them. Therefore, it is not advisable to carry out repeated treatments with them, since this will not be of any use. It is recommended to alternate fungicides containing different active substances.

Please note: Systemic fungicides work well in the early stages of disease development.

Complex

Such products are also called combined, that is, they combine the properties of contact and systemic fungicides. Along with their high efficiency in the fight against the rampant disease, complex remedies are not without drawbacks:

  • they are toxic to humans and animals;
  • they cannot be used during the period of fruiting and ripening of the crop;
  • Most drugs can cope with a certain type of fungus.

Composition and mechanism of action of the drug

The main substance of the Strobi fungicide is kresoxim-methyl . The drug is available in the form of granules that easily dissolve in water. Unlike analogues, Strobi penetrates into the very structure of the sheet, evenly distributed on the inside and outside. It is worth noting that the plant absorbs only a small part of the product. Pear and apple trees respond most clearly to the effect of the drug. Within a short period of time, the foliage becomes green, and this indicates the complete destruction of the scab. In most cases, this effect appears after the 3rd procedure of spraying with a fungicide.

Separately, it is worth noting that no traces of fungicide were found in grain crops after thorough treatment with Strobi. In apples its concentration is quite insignificant. Due to the fact that when it gets into the ground, Strobi quickly breaks down into individual molecules, it does not penetrate too deeply into the soil and does not pollute groundwater.

Grape diseases: description, signs

It is customary to divide grape diseases into several categories: fungal and viral. The first is the most famous and widespread. To cure infected bushes, the use of fungicides is required. The second category is the most serious. In most cases, treatment does not help; bushes have to be completely removed and quarantine measures must be observed.

Fungal diseases of grapes

  • Mildew (downy mildew). The most common fungal disease of grapes. It appears in the form of yellow spots and a gray (mouldy) coating. Affected areas dry out quickly without proper treatment. The disease develops at lightning speed in humid weather. Such a plant cannot be completely cured - the fungus is inside. It is only possible to prevent the course of the disease with the help of special medications.
  • Oidium (powdery mildew) is the second most common fungal disease. Affected leaves become covered with a gray coating. The disease can occur at any time in the summer. A favorable environment for the development of pathogenic bacteria is an air temperature within +25 degrees. Oddly enough, heavy rains can stop the spread of the disease. If the plant is severely damaged, the skin of the berries begins to crack and the fruits become unsuitable for consumption. If you don’t take any measures in time, you can be left without a harvest, and after 2-3 years you can completely forget about the existence of the vineyard.
  • Alternaria is a fungal disease. The main sign is the presence of brown or silvery spots on the plant. Leaves, fruits, petioles, and shoots are susceptible to the disease. If the blow falls on the berries, they become covered with a white film, shrink and quickly deteriorate. A long spring is a favorable condition for the rapid development of Alternaria.
  • Bacterial canker is a fungal disease that primarily affects grape vines. A clear sign is growths that appear on the shoots. There are no remedies that would help cure the plant. Therefore, it is better to immediately pull out the affected bush and burn it. It is noteworthy that grapes cannot be planted in its place for three years.
  • Apoplexy is a disease in which there is a sudden death of a plant. Experts explain this phenomenon by the fact that pathogens arise in the plant and produce toxins. They then destroy the plant. Weakened bushes are most susceptible to this disease.
  • Gray mold is a fungal disease. Appears as a gray coating. It can form on absolutely everything: shoots, tendrils, inflorescences, fruits, etc. The crop is not suitable for food. It is especially dangerous when the fungus forms on bunches of grapes. One infected berry can affect all fruits.
  • White rot is a clear sign of the disease; it is a white coating on the stalk and berries of the plant. Most often, the fungus occurs after a hailstorm - when the plant is damaged. Infected berries change color and subsequently fall off.
  • Black rot is a disease in which purple spots form on leaves and berries. Over time, they grow, and the affected areas shrink and fall off.
  • Verticillium - characterized by rapid withering of shoots. In the acute form, yellowing and falling leaves are observed. The plant can become infected through damaged branches or through the ground. The fungus persists in the soil for about 4-5 years, so planting grapes in an infected area during this time is not recommended.
  • Armillariasis is a clear sign of the disease - wilting of the leaves and damage to the roots (they become rotten and acquire a brown tint). Usually these signs appear in the spring, and in the fall yellow mushrooms grow on dead bushes.

Viral diseases of grapes

Viral diseases have been little studied to date. The disease can be caused by a certain group of viruses. In particular, we are talking about infectious chlorosis, yellow mosaic, rezuha mosaic, etc. The main signs that may indicate a plant infection with a virus include:

  • Slow development of the bush;
  • Dying of inflorescences;
  • Curling or any deformation of sheets;
  • Unusual leaf color, for example, variegated;
  • Wood cracking.

Unfortunately, no measures will help in this case. The affected bush is simply uprooted and burned. The infected area is not used for new plantings for at least 5 years.

Period of protective action

In case of minor damage by fungal diseases, the fungicide is effective for 14 days, in difficult situations - 10 days. To ensure a long-term protective effect, Strobi manufacturers recommend no more than 3 treatments per year. The optimal action of the fungicide is achieved through the correct alternation of products that protect crops from diseases and pests.

Strobi fungicide is a universal chemical substance, using which you can significantly reduce the risk of plants being damaged by fungal diseases. The crops you grow will remain healthy, and at the end of the season you will receive a large and high-quality harvest. The main thing is not to neglect preventive treatments in order to cure the plant at the initial stage of damage.

Before you start using the drug, you should read reviews about it.

Every year I use Strobi to spray the apple trees in the garden. I like that the drug has an affordable price and gives excellent results. After the first spraying, positive changes are observed: the foliage acquires a bright shade, the fruits do not fall off. The main thing is not to carry out more than 3 treatments per season.

Thanks to the fungicide Strobi, I was able to save my vineyard. In the spring I treated the vine, and in the fall even the harvest increased. In addition, Strobi does not have such an aggressive effect on plants as classical fungicides. In some cases, even one spray is enough. You just need to follow the instructions.

I was able to quickly get rid of powdery mildew in my garden. I sprayed phloxes and roses with Strobi. Three treatments were enough: in July, August and September. Dissolve the fungicide on the tip of a spoon in 10 liters of water. From personal experience I can say that Strobi acts much faster than other advertised fungicides.

How to use the drug "Strobi"

According to the instructions for use for grapes, the drug should be diluted in the following proportion: a teaspoon of granules (5 grams) per ten liters of water. The resulting solution is used to spray grapes throughout the growing season. It is necessary to treat not only the leaves, but also the branches and the ground near the roots. You need to use Strobi twice a week (or 10 days). Processing should be completed when there are about 30 days left before harvest.

To ensure that the use of Strobi for spraying is as effective as possible, follow the recommendations recommended by professionals:

  • This product can be used with both pesticides (Fastak, BI-58) and fungicides (Poliram, Delan). If you decide to combine it with other drugs, then you must check their compatibility;
  • To avoid the plant becoming accustomed to spraying with this product, it is necessary to periodically treat the bushes with drugs belonging to other groups;
  • Do not use the drug near sources of drinking water;
  • Spray in the morning or early evening.

In addition, it is important to know about safety precautions for working with this drug. If the solution gets on you when spraying, quickly take off your clothes and rinse your skin under running water.

If you accidentally inhale the drug, stay in the fresh air. If the Strobi solution gets into your eyes, rinse them thoroughly with water. If the drug is swallowed, drink as much water as possible and seek medical attention.

If you want the grapes on your plot to grow healthy and consistently produce high yields, use modern means for the prevention and treatment of various diseases.

"Strobi" is one of the best drugs in its class. It is he who effectively treats grapes infected with microbial and fungal diseases. If you follow the instructions for using the Strobi fungicide for treating grapes, you can quickly eliminate the source of infection. This pesticide does not allow the spores to develop further, stopping further development of the mycelium.

When is the use of Strobi indicated?

The effectiveness of the drug is quite high, which proves the possibility of using Strobi to combat:

  • late blight of nightshades;
  • scab;
  • rust;
  • oidium;
  • mildew;
  • anthracnose;
  • spotting of any origin;
  • gray rot.

The use of Strobi is indicated in case of detection of foci of infection with powdery mildew of cereal crops, grapes and cucumbers.

The best time to spray all crops is morning and evening hours

Application procedure

Strobes cannot be stored in opened packaging. The working solution of the drug is prepared immediately before use and must be consumed within 2-3 hours. The preparation method is usual: fill the tank halfway with water, make a mother suspension in a liter or half a liter of water, pour it into the tank while stirring. The tank is topped up to normal, closed, shaken vigorously several times and get to work. Every hour (if the work has been delayed to the limit), the sprayer tank also needs to be shaken.

Instructions for treating horticultural crops with Strobi fungicide are given in the table:

In all regulations, it is necessary to alternate Strobi with compatible fungicides that do not contain strobilurins.

The minimum acceptable interval between treatments is 10 days.

When alternating crops, it is not advisable to plant plants from the same systematic groups next year (nightshade after nightshade, pumpkin after cucumber).

For perennials, the first treatment is in spring, along the green cone (the beginning of the buds unfolding). Annuals are treated for the first time when the seedlings develop 2-3 leaves after planting in place. “Ground” annuals (sown immediately in a bed/container in a greenhouse) are treated for the first time when 3-4 true leaves are unfurled. Floral - the first time along the green cone and when the buds open. If roses suffer greatly from these diseases, the number of treatments can be increased to 3-4 per season, but then Strobi cannot be used in the same flower garden for the next year.

Note: according to empirical data from amateurs, Strobi is also effective against fly beetles and prevents bitter, moniliosis, penicillium and mold rot of fruits during storage.

In the vastness of large-scale agricultural technology, Strobi has so far more or less taken root only in medium-sized gardening. In large areas, the high and rapid resistance of pathogens to the drug is a huge disadvantage, and the services of specialists in accurately determining safe doses of pesticides and the content of their metabolites in products are not detrimental to the profitability of the farm. But for neat and attentive, even if not yet very experienced, owners, Strobi is truly a new generation fungicide

Beginning private owners or weekend summer residents should pay the most serious attention to this drug.

What is the purpose of the drug

The appearance on sale of a fungicide that is effective against severely damaged plants by pathogenic fungi and at the same time safe enough for use on ripening fruits caused a sensation at the time. Strobi has even been dubbed a new generation drug. True, the sensation did not completely materialize: the drug turned out to be quite difficult to use (see below) and causes resistance in the affected objects. However, the trail remains undeniable. its advantages:

  • The use of Strobi makes it possible to reduce the dose of toxic pesticides per unit of land area by at least 1.5-2 times.
  • The final treatment of the season with this preparation can be carried out at almost any stage of crop ripening, which sharply reduces its losses during storage.
  • A wide spectrum of action does not require accurate diagnosis of the disease and, accordingly, deep knowledge of agricultural technology by the user.
  • The drug is most effective when applied to wet foliage. In the temperature range of +(1-4) degrees Celsius, Strobe activity increases from initial to almost complete. That is, Strobi is most effective as a spring preventive fungicide for a garden or vineyard. Spring prevention with a safe product allows you to further reduce the consumption of toxic chemicals.

As a result, firstly, the drug Strobi has proven itself to be excellent in conditions of closely spaced plantings in small areas: fruits from adjacent plots of land to the treated area can be consumed without fear. Therefore, Strobi is already very popular in dachas and garden plots, see for example. video:

Video: Strobes for plant and fruit protection

Secondly, when the above-ground fruits of plants are intended for long-term storage. Tubers and tuber crops are much easier to protect from the accumulation of pesticide residues than pome fruits, stone fruits and berries. Therefore, Strobi was fully appreciated by gardeners, see the story:

Video: Strobes for spring garden processing

Fungicide Strobi stops the development of the mycelium of imperfect fungi and the sporulation phase; This drug only stops the growth of mycelial filaments. In fungi whose life cycle includes a stage of dispersal zoospores, Strobi deprives the latter of their motility. Since the life cycles of pathogenic and beneficial soil lower fungi are very different, Strobi has virtually no effect on soil-forming fungi when used correctly. Action Strobi preim. contact: the dried working solution forms a dense film on the plants that is not washed off by rain; The drug penetrates into plant tissues weakly, only while the working solution dries.

Fungicide Strobi description

The contact action drug is produced in the form of water-dispersible small brown granules, which are diluted with water. The main active ingredient that is part of the fungicide is kresoxim-methyl.


The active substance, falling on the leaves, is evenly distributed throughout all parts of the plant, suppressing the growth of fungal cells in them and the appearance of secondary spore formation. The fungicide is safe for the environment, animals and pollinating insects. The drug does not accumulate in fruits and is considered a biological means of combating plant diseases.

The drug Strobi is effective when treating wet leaves on one side, and can also be used during various periods of plant development, including flowering.

The solution forms a film on the surface of plants that is resistant to moisture. The fungicide is also resistant to atmospheric conditions and temperature changes. Having spread to various types of fungi, it does not require diagnosis of a specific disease.

Strobi is little absorbed into the soil, does not affect the composition of the soil, and after watering it decomposes into acids that do not pose a danger. Suitable for treating plants before winter and early spring, starting from above-zero temperatures.

The fungicide is well tolerated by crops and is compatible with other insecticides and fungicides, which is convenient for the use of complex plant treatment. Can be used both in open areas and in greenhouses.

Due to the low danger to living organisms and the ability of fungi to mutate, it is recommended to alternate fungicides and use drugs with different modes of action together. Analogs of the drug Strobi with a similar substance and principle of action are Boxwood, Strobitek. Instead of Strobi, Trichodermin and Prestige are used.

Strobes are used in tank mixtures with other drugs for a complex effect not only on diseases, but also with the use of insecticides on insect pests. Compatible fungicides: Delan, Cumulus, Quadris, insecticides: Bi-58, Fastak.

Advantages of the product

Many gardeners and agronomists have already been able to verify that Strobi has a wide range of advantages:


  • Possibility of treating plants during their flowering.

  • The drug is not harmful to humans, beneficial insects and animals.
  • Good resistance to low temperatures (down to -4⁰С).
  • The drug was created for the prevention and treatment of most types of garden plants.
  • When it gets into the ground, the components quickly decompose.
  • After the plants have been treated, the active substances retain their protective properties for a long time.
  • Timely use of Strobi ensures effective fight against various diseases.
  • The drug can be applied even to damp trees.
  • Strobi is evenly distributed over the surface of the leaves.
  • The product is resistant to heavy rainfall.
  • The active substances penetrate the leaf epithelium even after treatment on one side.

Depending on the degree of plant disease, the action of the fungicide appears within 2 hours for a minor infection or after 2 days for a serious plant disease. If the treated crop belongs to the middle class of infection, then the protective properties of Strobi will be preserved for 10 or 14 days. When the plant is in critical condition, the drug will act for a maximum of 2 weeks.

Rules

Strobi fungicide is dangerous to humans in direct contact, so treatment should be carried out in personal protective equipment.

Even if the substance disintegrates quickly, poisoning is possible. When starting an event, it is imperative to protect yourself from possible exposure of Strobe to open areas of the body, hair, eyes, and other mucous membranes.

  • There should be a protective cap or scarf on the head, tied in such a way as to eliminate the possibility of getting on the hair. On top of your clothes, it is advisable to wear a robe or overalls that completely covers the body.
  • You should wear rubber gloves on your hands.
  • It is advisable to protect your eyes with special glasses or a mask.

It is recommended to inhale the vapors of the solution as little as possible to avoid intoxication. If, however, a person has inhaled vapors, it is necessary to stay in the fresh air for a long time. Contact with the mucous membrane of the eyes is eliminated with plenty of running water.

Important points when working with fungicide

Summer residents and farmers who have purchased the effective Strobi product must take into account the following nuances:

  • The best time for spraying is considered to be early morning and evening, when the air temperature has dropped.
  • With frequent use of the drug, resistance may develop.
  • Spraying is best done in calm and windless weather.
  • Considering the toxicity of the product, you should not neglect protective measures.
  • Each Strobi treatment must be preceded by spraying with a quality preparation that does not belong to the class of strobilurins.
  • It is forbidden to prepare the working solution in advance.
  • After spraying, you can work with plants no earlier than 3 days later.
  • At the end of the work, gloves and work clothes must be soaked in a soap-soda solution.

Precautionary measures

The drug should be stored in a specially designated place.

The fungicide has a detrimental effect on fish and can rapidly infect water bodies, so application near lakes and rivers should be carried out with great caution - do not spray during windy weather. If there is a beekeeping farm nearby, spraying must also be carried out in compliance with safety rules, since insects may die if exposed to the fungicide

It is recommended to protect the apiary from contact with the product - transport it to another place or close the exits from the hives

If there is a beekeeping farm nearby, spraying must also be carried out in compliance with safety rules, since insects may die if exposed to the fungicide. It is recommended to protect the apiary from contact with the product - transport it to another place or close the exits from the hives.

Description of the drug

The product has shown its effectiveness in the treatment of many diseases caused by fungi. Manufactured in Germany. Available in bags, it looks like water-soluble granules of light brown color. Dissolves in water at 20 °C in an amount of 0.002 g/l. Refers to substances of the 3rd hazard class.

Compound

The chemical is part of the class of strobirulins. The active substance in Strobi is kresoxyl-methyl, which has a high level of bactericidal activity. Preparations containing this chemical substance have therapeutic and protective properties. Treatment is carried out only if there are obvious symptoms of the disease.

Mechanism of action

“Strobi” is an effective drug belonging to a new generation of pesticides that simultaneously treats several diseases of grapes and many other plants. Its action is to suppress the development of pathogenic microorganisms. The main advantage of its use is that it does not harm animals and people.

Area of ​​influence

The pesticide acts systemically and locally, suppresses the cellular respiration of the fungus, leading to its death. It inhibits the spores that form and reduces the rate of spread of this disease.

Period of protective action

If fungal diseases cause minor damage to the grapes, the drug is effective for 2 weeks. In other severe cases - about 10 days.

To obtain maximum effect, it is necessary to correctly alternate chemical treatment agents.

Frequency of treatments

Standard instructions for using the Strobi fungicide for grapes involve treating the bushes 2 times. Between the first and second procedures there is a break of 7-10 days. The remedy is universal because it is used not only for prevention, but also for treatment.

Waiting time for grapes

It is appropriate to carry out treatment throughout the entire growing season. Both leaves and soil in the root zone, berries and vines are sprayed. The mixture is used twice within 7-10 days. Treatment is stopped a month before the start of berry picking.

Description of the fungicidal agent

Strobi is a new generation universal drug that is widely used against pathogens of fungal diseases. The active substances of the fungicide act on fungi that infect the leaves, the product stops the growth of mycelium and stops sporulation, blocks disease outbreaks and prevents spores from germinating.

Thanks to its high efficiency and unique composition, the drug helps to cope with diseases that arise as a result of spore germination. Strobi belongs to a unique type of strobilurins (substances that inhibit cell division of pathogenic pathogens due to their effect on individual enzymes). Even a small amount of this product can cope with pathogenic fungi.

The components included in the fungicide are completely safe for people and animals. Some mushrooms can mutate and become invulnerable to many means. This is the disadvantage of the drug. Experts say that to achieve a good result from using a fungicide, it is necessary to use it in the correct proportions, which are always indicated in the instructions.

How to use the drug correctly, instructions for use?

“Strobi” is a broad-spectrum fungicide, the instructions for use of which are very easy to understand, and reviews from gardeners and gardeners, in most cases, are quite flattering.

How to use "Strobe" for flowers?

When growing flowers, experienced gardeners spray them with fungicides to combat powdery mildew and leaf rust. In this case, the drug “Strobi” is used to prepare a solution, the instructions for use are as follows: dissolve 5 grams of fungicide in a bucket of water. The resulting solution remains most effective for two hours after preparation, so it must be used rationally during this time. During the growing season, it is better to treat flowers using a sprayer, spraying three times a month.

Using the drug in the garden

The drug "Strobi" is perhaps the safest fungicide for garden plants, and for grapes in particular. It effectively prevents the proliferation of fungal diseases that appear on the fruits and leaves of plants. Even after infection with a fungus, the Strobi fungicide effectively treats the infected object, and then eliminates the disease by suppressing sporulation and mycelial growth. Due to the fact that new spores no longer germinate, large-scale outbreaks of the disease can be prevented. If the plant was infected for the first time, then “Strobe” also has a protective effect against future attacks of viruses.

This drug helps cope with black spot, powdery mildew, basal shoot cancer, scab and rust. The drug "Strobi" can also be used for grapes for preventive purposes, despite the fact that the instructions for use indicate the possibility of spraying only during the growing season. The treatment affects leaves, fruits, trunk and soil in the root zone. Grapes should be sprayed twice every 10 days. The last treatment is carried out a month before harvest.

Other fruit trees should be treated with Strobi fungicide during the growing season (up to three times throughout the season). Treatment is carried out at two-week intervals. “Strobi” should be alternated with other fungicidal preparations: “Skor”, “Cumulus DF”, “Bordeaux mixture”. The last treatment of fruit trees is carried out no earlier than 35 days before harvest.

Instructions for use of "Strobi" for vegetable crops

Vegetable crops, by analogy with fruit trees, are processed during the growing season. The best conditions for the procedure are dry, windless weather.

When using Strobi as a fungicide for vegetable crops, remember that the instructions, in particular for tomatoes, peppers, carrots and other crops, are generally the same. This drug effectively copes with late blight and powdery mildew of tomatoes and carrots, downy mildew of cucumbers and other diseases.

Fruit-bearing vegetable plants are treated by spraying, but it is better to use “Strobi” in combination with “Quadris” or “Abiga-Pik”. The treatment cycle is as follows: first, spraying is carried out with the “Strobi” composition, then with another fungicide, and then again with “Strobi”. Next year, it is recommended to plant others instead of the treated vegetable plants.

Vegetables should be sprayed twice during the growing season, and the waiting time from the last treatment until harvest depends on the specific crop:

  • for tomatoes and cucumbers growing in open ground - this is 10 days.
  • for tomatoes in closed ground - 5 days.
  • for cucumbers in closed ground - 2 days.

Area of ​​effect of the fungicide

The drug Strobi for planting grapes is used in cases of infection:

  • black spotting, as well as white and brown, ring spotting;
  • white and gray rot of stems;
  • mildew;
  • scab;
  • white rust, leaf spot;
  • anthracose;
  • oidium, etc.

The fungicide demonstrates its best qualities in preventive measures. With his help and participation, it is easy to prevent the appearance of diseases or pests.

Description of the drug

The drug Strobi was developed by BASF based on the natural toxins strobilurins. The main working substance of the fungicide (kresoxim methyl) does not contain metals, as well as phosphorus, sulfur and chlorine. It almost completely and quickly disintegrates in the soil, leaving behind a harmless acid, which, in turn, also disintegrates in a short time into very elementary components that do not cause any harm to the soil and agricultural products grown on it. The product is produced in the form of VDG granules containing 50% active ingredient.

The drug has only one systemic drawback - which, however, can be corrected by correct use in accordance with the instructions: the fact is that the drug causes resistance in the objects of treatment, that is, addiction, especially with excessively frequent and excessive quantitative use. Because all types of fungal diseases mutate easily. And then even such a proven drug as Strobi becomes powerless.

Over the course of two decades, Strobi analogs have been developed that will help in case of resistance to the drug. These are Trichodermin, Strobitek and Skor. Powdery mildew of cucumbers and cereals and gray mold, which parasitizes vegetables in greenhouses, are especially resistant to the drug.

Advantages and disadvantages of application

The chemical preparation "Strobi" for grapes has disadvantages, such as its toxicity and negative impact on the environment. The plant may become addicted to the substance, which is why it is necessary to look for an alternative remedy.

However, the drug has many advantages:

  • efficiency;
  • safety for the plant;
  • resistance to weather changes;
  • penetration into plant tissue (spraying is possible only on one side);
  • safety for bees.

Preventive measures against fungal diseases

Unfortunately, if the disease has already begun to spread throughout the grape bush, it can be very difficult to cure.
Therefore, it is recommended to carry out preventive measures - preventive inspections of all areas of the bush, useful spraying and tillage. Please note! You need to be especially careful with plants that are not resistant to diseases. They require more frequent treatments with fungicides and other protective measures. It is necessary to regularly inspect the vines and leaves, promptly remove rotten and shriveled areas

The first preventive spraying is carried out immediately after removing the winter shelter before the period of swelling of the buds

It is necessary to regularly inspect the vines and leaves, promptly remove rotten and shriveled areas. The first preventive spraying is carried out immediately after removing the winter shelter before the period of swelling of the buds.

Tip! For the first treatment, you can use 3% Bordeaux mixture, copper sulfate or any “weak” fungicide.

Sanitary pruning will allow the plant to direct its energy to the growth of healthy shoots. Removing excess branches that thicken the bush will allow air to better penetrate inside the crown, which means the risk of excessive moisture and fungus will be significantly reduced

It is also important to keep the soil clean: remove weeds that are carriers of infections in a timely manner; loosen the soil to saturate it with oxygen, apply fertilizing to increase the immunity of the grapes

Dosage and rules of use

As a rule, a sachet of the drug weighing 2 g is enough for one application for various crops. The ratio of water and fungicide in each specific case must correspond to the instructions. To achieve maximum effect, you should adhere to the following processing rules:

It is better to spray Strobi at a certain time - in the morning or evening, in calm weather; It is important to follow the recommended precautions when working; caring for the garden after using Strobi should be stopped for 3 days; you need to treat the stems, leaves, fruits and root zone of plants; for best effectiveness, before using Strobi, it is useful to pre-treat the crops with a fungicide of a different action according to the instructions on the package; spraying should be carried out no later than 7 days after the end of the rainy period, when the risk of pathogen development is highest.

Important! Late blight, powdery mildew and other fungal infections develop rapidly in a humid environment in rainy weather

For grapes

In terms of effectiveness and safety, Strobi is considered one of the best fungicides for vineyards, helping to suppress the growth of mycelium and treat vines already affected by fungi. It protects the crop from other types of pathogens.

Instructions for use for grapes:

  1. One sachet of Strobi (2 g) is dissolved in 6 liters of water.
  2. Spray 2 times per season.
  3. The last treatment is carried out at least 28 days before harvesting.

For trees

Fruit trees are most susceptible to scab and powdery mildew. When using Strobi, the processes of germination of fungal spores are significantly slowed down, and the development of other damage, for example, rot, stops. For maximum effectiveness, it is recommended to alternate or mix Strobi with other fungicides, for example, Horus, Ridomil.

Instructions for use for fruit trees:

  1. A packet of powder is dissolved in 1 bucket of water.
  2. Spray no more than 3 times per season.
  3. Stop processing 3 weeks before harvesting the fruits.

Important! The effect of the drug is especially noticeable on apple and pear trees, the foliage of which, after treatment, becomes rich green, healthy and shiny.

For flowers

Powdery mildew and rust are destructive to many types of flower crops. To prevent plants from becoming accustomed to the frequent use of Strobi, the instructions recommend combining the fungicide with similar agents or alternating it with drugs of a different mechanism of action. Strobi is used for flowers only one year, the next year the treatment is excluded.

Instructions for use for flowers:

  1. 2 g of powder are diluted in 5 liters of water.
  2. Spray every 10 days.

Instructions for using Strobi for garden roses are as follows:

  1. Treatment is carried out every 2 weeks, the last time before sheltering for the winter.
  2. Spray the rose bushes carefully, always including the near-standard circle in the treatment area.

For vegetables

A fungicide for vegetable crops is used for various infections. Tomatoes most often suffer from late blight, cucumbers are susceptible to powdery mildew, and downy mildew is observed in onions and garlic. Spraying of vegetables is carried out not only when infected, but also to prevent the above diseases.

Instructions for use for vegetables:

  1. A sachet of the drug is dissolved in 10 liters of water;
  2. Treat with an interval of 10 days in open ground and 7 - 8 days in closed ground.
  3. Spraying is stopped no later than 12 days before harvest.

For maximum effectiveness, it is recommended to alternate Strobi with other fungicides. It will not be used the following year. For preventive purposes, it is necessary to observe crop rotation, correctly changing the planting location.

Rules of application

Each gardener determines the timing of use of the drug for himself - the treatment of grapes with the Storby fungicide can be carried out at any time of the year, especially on protected ground. However, the substance shows the greatest effectiveness and benefit during the spring-summer flowering and fruiting period, when, due to climatic conditions, grapes are susceptible to damage by various fungal infections. Also, it would not be superfluous to treat the plant before flowering as a preventive measure.

However, the substance can cause addiction and reduce resistance, as a result of which its application is not recommended more than three times a year. If you need to apply this type of pesticide, it is best to wait until next season or use another chemical of this type.

"Storby" is used according to the following instructions:

  • Before using them in the spring, it is recommended to prune the grapes by removing infected or dead branches. Also remove broken vines and shading shoots, in the depths of which harmful mycelium can develop unnoticed.
  • Next, a solution of the drug is made in a proportion of 5 g per 10 liters of warm water.
  • Over the next two hours, the grapes should be processed, after which the solution will erode and its effect will cease.

Analogs

If Strobi is not commercially available, then you can use drugs with a similar principle of action. Ardent is a pesticide based on kresoxim-methyl, which is used for the prevention and control of oidium and powdery mildew in vineyards and fruit trees. This product is available in the form of a concentrated suspension, packaged in 1 liter plastic bottles.

Kart is used to combat root rot and rust on grain crops. The fungicide contains two active substances that provide plants with a quick healing and protective effect. The disadvantage of the chemical drug is its narrowly targeted effect and high cost.

Collis contains kresoxim-methyl and boscalid, which protect the fruits of the grapevine both from the inside and outside. The systemic fungicide is available in the form of a concentrated suspension. The drug is used against powdery mildew in vineyards. The operating principle is similar to the Strobe operating principle.

If you need a pesticide with a different composition, then Fundazol is popular among gardeners. The best drug with a wide spectrum of action against common types of fungi. The advantage of the chemical is its ability to penetrate tissue, quickly destroy pathogens and provide protection for 2 weeks. With regular use, the infection becomes resistant to the ingredients.

Azoxystrobin is the active ingredient of the systemic fungicide Quadris from the strobilurin group. This powerful drug is used to combat all known pathogenic fungi. The suspension concentrate destroys disease spores and maggots and protects plants from re-infection. It is non-addictive and has a short harvest period of 5 days.

The fungicidal drug Skor based on difenoconazole belongs to the chemical class of triazoles. The components penetrate into the tissues of cultivated plants and reduce the intensity of reproduction. It works well in the temperature range from +14 to +25 C. The contact pesticide helps fight all types of plant diseases, especially against:

  • Phomopsis;
  • black rot;
  • oidium.

Among the safe analogues of the fungicide Strobi, it is worth noting Fitosporin-M. This antifungal biopesticide based on the hay bacterium is used for prevention and at the first symptoms of diseases. It suppresses the activity of pathogenic microorganisms and creates unfavorable conditions for their reproduction. Part of the drug includes anti-stress additives that help crops recover.

Combination with other drugs

The drug "Strobi" can be used in conjunction with other drugs, but it is recommended to check them for compatibility first. Manufacturers say that the product can be used together with pesticides such as BI-58 or Fastak, as well as fungicides such as Polyram or Delan. Reviews from experienced winegrowers indicate a positive experience in combining Strobi with Quadris and Abiga-Peak. All other combinations must be carried out very carefully to avoid unwanted chemical reactions that will cause more harm to the plants than good.

Advantages of the drug

In the fight against fungal diseases, a huge number of pesticides have been synthesized - Quadris, Ridomil Gold, Chorus. They have properties similar to the strobe fungicide, but are inferior in many respects:

  • Low toxicity and safety for bees, animals and humans. This property allows processing to be carried out in any period of the growing season, including during the flowering of grapes.
  • Possibility of spraying on wet leaves and grass. Resistance to precipitation.
  • Versatility. The drug destroys mycelium, disinfects the soil, and treats affected plants from most fungal diseases.
  • High profitability. The drug has a good ratio of effectiveness and price.
  • Independence from ambient temperature. You can start work at a temperature of +1°C.

Compatibility with other drugs

To save processing time, gardeners often use tank mixtures. They include fungicides, insecticides, growth stimulants and fertilizers. The drug strobi is compatible with almost all of the listed components.

Strobi combines well with the fungicides quadris, ridomil gold, topaz, etc. It is also used with insecticides. Instructions for use of a mixture of the drug strobi for grapes:

  • 2 g of strobe fungicide is dissolved in 3 liters of water at a temperature of 20-22 °C;
  • Separately, an ampoule of Neoron insecticide (125 ml) is stirred in the same volume of liquid.
  • stimulants Epin or Zircon (1 ml) are added to 2 liters of water;
  • all three components are combined, and the volume is brought to 10 liters of water.

Additional Information! Strobi is resistant to being washed off by rain, which cannot be said about other preparations, so an adhesive or soap solution can be added to the mixture.

This mixture as a whole will increase the effectiveness of protecting the vineyard from diseases and pests, and will also help accelerate growth, increase immunity and productivity.

But you should always remember that not all components are compatible, and they must be entered in strict sequence:

  • first of all, you need to dilute the powder preparations, they dissolve in water and are introduced into the solution;
  • the second are liquid pesticides or components in the form of an emulsion;
  • the final ones will be growth stimulants or fertilizers.

Important! It is always necessary to maintain the proportions of the drugs, their violation can lead to even greater harm to the plant

Invalid connections

Incorrect composition of drugs can lead to stratification of the mixture and loss of therapeutic functions. Strobi fungicide cannot be used in the following compounds:

  • copper-containing preparations (including copper sulfate, Bordeaux mixture);
  • fertilizers containing copper, zinc and iron.

The modern fungicide strobi opens up new prospects in the fight against harmful fungi. Thanks to its mechanism of action and safety, it is among the top most popular drugs for the treatment and prevention of grape diseases.
