Strobi preparation: instructions for effective use for grapes + reviews

Composition and mechanism of action of the drug Strobi

Biological, created on the basis of natural toxins, Strobi fungicide is a universal remedy for combating fungal diseases of cultivated crops. According to the instructions, it is characterized as a highly effective product, the effects of which are detrimental to all types of pathogens. Its use is permissible at all stages of plant infection. The safety of using Strobi is due to its low toxicity. On the one hand, this is an undeniable advantage, on the other hand, it is a disadvantage. For example, when using Strobi for apples and tomatoes, no residual substances from the fungicide were found in the fruits. However, it is the low toxicity that forces pathogenic microorganisms to mutate, which increases their immunity to the protective agent.

The action of the fungicide is strobilurin, that is, a substance that inhibits the cellular respiration of fungal pathogens. Even in small quantities, strobilurins effectively fight fungus without harming other living beings - plants, animals or humans. The local-systemic action of Strobi is aimed at protecting and treating cultivated plantings and suppressing the development of fungal growths on leaves and fruits. The active substance in the composition is kresoxim-methyl, which has a detrimental effect on most pathogenic microorganisms. A fungicide can simultaneously replace several drugs of similar action.

Action

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.

Release form of the drug Strobi

An effective preparation for treating plants, Strobi is a water-soluble granule, which is produced in bags weighing 2 g. Less commonly, you can find packages of 100 g on sale. According to the instructions, its use is most effective in the first two hours after preparing the solution.

Main characteristics of the drug

Strobi fungicide, according to experts, is a unique invention of modern farmers.
The universal and powerful product provides reliable protection for almost all plant crops from fungal pathologies.

It is especially effective in treating:

Vinogradnikov

Berry and ornamental shrubs

Fruit trees

Vegetable plantings

garden flowers

The drug showed the greatest activity and high level of impact against the fungal disease scab.

The effect of the treatment becomes visible after 3 times of using the product. High protective qualities are due to the effective composition.

Active biocomponents penetrate the structure of plant crops and act at the molecular level.

This brand of fungicide not only destroys fungi, but also stops the formation of secondary pathogenic strains.

Unique composition

The main active ingredient of Strobi is kresoxim-methyl, which belongs to the group of chemical compounds of the strobilurin class. A feature of the components is their increased degradability - these substances do not accumulate in the structures of plant tissues, water bodies and soils.

Scientific research has proven that after treatment, the Strobi fungicide does not leave any traces in grain crops. In apple varieties, residues of the substance were found in microscopic quantities.

The big advantage of the drug is its low toxicity.
But this fact also becomes a disadvantage. Since fungal parasites are characterized by rapid mutation, this causes resistance (resistance) to subsequent influences. This feature was recorded:

• In cucumber varieties and cereal crops in the treatment of powdery rot.

• In vegetables in the fight against gray rot.

Ask a Question

The highest activity of strobilurins is observed immediately after preparation of the mixture. The maximum time for using the product is 2 hours after preparation. Therefore, it is recommended to dilute the drug immediately before use and not store the remaining mixture.

Release form

For the convenience of preparing the solution, the drug is available in instant granules.

More often, packaged packaging of 2 g is found on sale.

But you can also see larger quantities of 100 g in specialized stores.

Scope of application

Strobi fungicide can be treated at any stage of infection with fungal diseases and for prevention:

• vineyards;
• fruit trees;
• ornamental and berry crops;
• vegetables;
• flowers.

The use of the drug according to the instructions is advisable for the following diseases:

• different types of powdery mildew;
• scab;
• gray, black, dry, brown spotting;
• rust;
• basal cancerous formations of shoots;
• late blight;
• anthracnose;
• gray mold;
• mildew.

In other words, the fungicide can be used for absolutely all common fungal diseases. For each crop, Strobi is used according to specific instructions, observing the dosage and the recommended number of treatments.

How to use Strobi in vineyards and flower beds

When to treat the area? To obtain maximum effect, it is better to use the drug early in the morning or at sunset.

The fungicide is able to reliably protect a vineyard or garden flower bed from fungal diseases, from the effects of oidium and mildew. To dilute 12 liters of solution you will need to use a small dose - only 4 grams of concentrate. To be on the safe side, grapes, roses, and flower beds are sprayed with this solution twice with an interval of 10 days between spraying.

Tomato processing

Of the vegetable crops, tomatoes most often suffer from fungal diseases, especially those varieties that need abundant watering. Other vegetable plants are also susceptible to these diseases, but less so. Usually the disease occurs due to prolonged rains.

Advantages and disadvantages

The advantages of using a fungicide are:

• the ability to use it during flowering plants;
• absolute safety for processed crops, animals, birds and bees;
• ability to act even at low temperatures (down to -4 oC);
• used not only for treatment of fungal damage, but also for prevention purposes;
• ability to process a wide range of cultivated plants: Strobi is equally effective for garlic and onions, as well as for chrysanthemums, roses and fruit trees;
• resistance to precipitation, which allows it to be used on wet foliage during the rainy season;
• long-term effect of the drug, the period of which is up to 1.5 months;
• the ability of rapid hydrolysis, which does not allow active components to accumulate in fruits;
• environmental safety due to rapid decomposition;
• uniform distribution of the active substance over the entire surface of the leaves, which contributes to the appearance of a protective film that does not allow the development of fungal spores.

The disadvantage of Strobi fungicide can be considered its low toxicity, which contributes to the emergence of resistance to the active components of fungal pathogens. Regular use of the product makes it less effective due to the ability of fungal spores to mutate. So, following the instructions for using Strobi fungicide for cucumbers and regularly alternating it with other antifungal components, you can achieve excellent results. However, with constant spraying of cucumber vines with one drug, the effectiveness decreases.

Important! The cost of the fungicide is quite affordable and commensurate with its quality.

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:

Features of preparing the solution

Dry granules are diluted in water according to the instructions for a specific crop. The solution is poured into a spray bottle and work begins immediately. Maximum effectiveness can only be achieved when using a freshly prepared solution. It cannot be stored ready for processing. The product dissolves perfectly in water, leaving no sediment and, when sprayed, penetrates into the leaf structure, protecting the plant from the outside and inside. When Strobi hits only a small part of the plant, the product itself is distributed over the entire surface.

When to use

• Almost all types of spotting;
• late blight;
• rot;
• powdery mildew and scab;
• all types of rust;
• rabella, rubella, tinder fungus;
• mildew;
• Stemphylliosis

Strict adherence to the instructions is mandatory, because the number of treatments per year is set individually for each garden or vegetable crop.

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.

Instructions for use "Strobe"

The best conditions for using Strobi are dry, clear and calm weather (no wind).

The rules for using the product say that each type of crop has its own timing and dosage:

1. Shrubs, fruit trees and grapes need to be sprayed at least 2 times over 1-1.5 weeks. The last treatment is carried out approximately 30 days before harvesting.
2. Flower plants should be sprayed in the same way (2 times a month). Duration - starting from mid-summer to its end: July (from the 1st to the 31st inclusive, or from the 1st of August to the 31st).
3. Roses of garden varieties will need to be additionally treated with the composition before preparing for wintering.

Vegetable crops need to be processed twice during the growing season. Before harvesting, wait a certain period of time:

• at least 10 days – for tomatoes and cucumbers grown in open ground;
• 2 days – cucumbers growing in a greenhouse;
• 2 days – tomatoes in closed ground.

It is best to carry out processing in the morning or evening.

Precautionary measures

For safety reasons, when working with fungicide, you should adhere to the following precautions specified in the instructions:

• carry out processing with gloves and safety glasses;
• put on overalls, which should be washed after work;
• do not smoke or drink while spraying;
• limit the access of animals to the treated area;
• After the procedure, wash your hands thoroughly and take a shower if necessary.

Attention! The skin or eyes are washed with plenty of water if the fungicide comes into contact with them.

Systemic or contact fungicide

Strobi is a systemic drug that can completely destroy fungal pathogens. In addition, it suppresses the reproduction of spores. The fungicide is effective against powdery mildew, oidium, and rot.

Strobi is used even for the most minor damage to vines, leaves, and grape bunches. The maximum number of treatments is no more than 2 times per season. To make a solution, take 2 grams of the substance per 7 liters of water. The resulting liquid is sprayed onto the plants. The active ingredient is completely safe for people and animals.

Analogs of fungicide Strobi

Among the protective agents of a similar spectrum of action, based on strobilurins, Prestige, Trichodermin, Topsin M stand out. They appeared on sale back in the 90s of the last century and since then have been especially popular among gardeners and gardeners. If you follow the instructions for use, they show excellent performance when used.

How to prepare the solution

The fungicide can be used for both prevention and treatment of the vast majority of cultivated plants. The processing area includes grapevines, fruit trees and shrubs, as well as flowers. Nightshades also respond well to treatment: potatoes and tomatoes, as well as tuberous vegetables such as beets and carrots. The solution for use is made half an hour to an hour before starting to treat the plants.

The concentration of the drug may depend on the purpose of use. Fruit trees are treated with Strobi fungicide no more than three times during the entire growing season, and the interval between applications of the drug should be at least 2 weeks.

Concentration: 2 grams of fungicide are dissolved in 10 liters of water. 1 square meter of area is treated with approximately 150 milliliters of solution.

It is better to alternate treatment with Strobi with agents of similar action (already mentioned Skor, Strobitek, Trichodermin.

25 days before the planned harvest, you need to stop using fungicides - the already applied drug will reliably block the paths of infection.

Application cycle

1. Spraying plants with Strobi.
2. After a week, they are treated with other means. These could be “Quadris” or “Abiga-Pik”, which also belong to strobilurins.
3. After another week, re-treat the areas or plants with Strobi fungicide.

Reviews

“I am engaged in growing vegetables. I recently started using the drug Strobi and was completely satisfied with the effect. I spray strictly according to the instructions. Does an excellent job of protecting tomatoes, cucumbers and other vegetables.” — Anna left a review.

“I really love flowers. Different varieties of roses bloom in the flowerbed all season. Last year they got powdery mildew. I was already thinking about cutting off the bushes, but my friend’s advice saved me. Before sheltering for the winter, as described in the instructions, I treated it with Strobi. In the spring my roses were absolutely healthy.” — gardener Yana shares his experience.

“The grapes require a lot of attention and care. Without preventive treatments, it will not produce crops and, sooner or later, will die. However, the drugs need to be changed, since pathogenic microorganisms mutate and they no longer respond to it. Therefore, it is necessary to change fungicides quite often. Lately I have been using only Strobi. As they write in the instructions for use, and also, according to reviews, it is not only effective against many fungal diseases, but also safe for the environment.” — Andrey comments on the fungicide.

Detailed description

The drug "Strobi" is a product of a plant owned by the German concern BASF. The company's scientific laboratory has demonstrated the high effectiveness of the active substance from mycelium against pathogenic microflora that appears on plants. It was obtained from the natural mushroom Strobilurus tenacellus, which grows in nature.

"Strobi" is produced in the form of granular powder, which is packaged in plastic packaging. Each pack has sealed edges. The product is available for purchase in packaging sizes from 2 to 200 g. The drug must be diluted for spraying plants.

Advantages and disadvantages

The local-systemic remedy is a universal antifungal drug that copes with a large number of diseases. The chemical evenly covers the leaves and shoots. Special additives in the composition improve adhesion, which allows the poison to be used on wet plates. Strobi fungicide is resistant to rain and will not be washed away by precipitation or heavy irrigation.

The pesticide is classified as hazard class 3 and is non-toxic to warm-blooded animals and pollinators. The product can be used during flowering plants. To protect bees from exposure to poison, farmers maintain a sanitary zone 2 km from the processing site.

The chemical creates a thin film on the surface of crops that kills spores and protects against new invasion. Spraying can be carried out at all stages of disease development. With a small infection, the pathogens will die in 2 hours; with a strong spread, therapy will take a week. The pesticide does not decompose under the influence of heat and cold, and is not afraid of ultraviolet radiation. If dosage standards are observed, it is not addictive.

Adviсe

• The best time to treat a garden with a fungicide is morning and evening, at sunrise and sunset.
• Yes, the drug is almost non-toxic. But still use protective equipment.
• It is better to process crops in calm conditions and in the absence of rain (although this is not critical).
• Prepare only fresh solution! The shelf life of the diluted drug is very short - no more than an hour.
• After spraying, do not do anything in the garden or vegetable garden for three days. Except, perhaps, for watering.
• Not only the green and supporting parts of garden crops are processed, but also the root zone along with the area of ​​soil directly adjacent to the plant (only the surface, without loosening).

Due to the rapid hydrolysis of the components of the drug, it does not accumulate in the fruits. Analysis of the harvested apples showed an insignificant amount, and even then the drug residues disappeared during repeated tests after 5-6 days. And in grains it was not detected at all once after the initial processing of the harvested crop (winnowing and storage).

Since fungal diseases become widespread mainly after rains, no later than a week after they have passed, it is necessary to treat the plants and soil with fungicides. In cases where it rains continuously, do not wait for it to end - this way at least some part of the harvest can be saved.
