Composition, purpose and release form of the fungicide "Benorad"
The one-component drug consists of benomyl of the benzimidazole class. A kilogram of product contains 500 grams of a white crystalline substance with a slight irritating odor.
When benomyl breaks down, it releases the substance butyl isocyanate, known for its fungicidal properties. After processing the plants, the active substance remains for a long time without being washed off.
The value of the drug is that it is used for:
- dressing the seeds of coniferous trees to avoid molding;
- processing of tubers and bulbs of flowers, indoor and garden;
- spraying grain crops against diseases caused by gray rot, fusarium, and loose smut;
- treatment of powdery mildew, sugar beet blight.
The drug is produced by the company "August" in bags of 12 kilograms. Wetting powder is used to prepare a suspension.
Mechanism of action of the product
Benomyl (foundazole) enters the plant cells. After its transformation into carbendizyme, it begins to show activity against fungal infections. The fungicide acts on the surface of the leaves, protecting against the spread and growth of spores. Protection is created due to the penetration of pathogens into plant tissue.
The main function of foundationazole is to suppress the activity of the reproductive system of the pathogen on the vegetative parts. The effect of the drug does not apply to new leaves that appear.
In addition to fungicidal properties, the main component of Benorada suppresses spider mites and melon aphids. The development of buckwheat leaf beetle is stopped under the influence of the drug. It also affects the spread of nematodes living in the soil.
Advantages and disadvantages
The advantages of using Benorad are that the product:
- has a systemic effect;
- treats and protects plants, seeds, tubers;
- effective against a wide range of diseases;
- combined with other drugs to enhance the fungicidal effect.
The disadvantage of the drug is that it fights fungi in those areas that are etched. It does not spread further along new leaves and stems, so it is necessary to use the fungicide several times. It should be noted that the drug is highly toxic to humans.
Period of protective action of the product
After spraying, the fungicide acts against pathogens within 24 hours, blocking their growth and reproduction. 3 hours after spraying, the drug remains on parts of the plants without being washed off by rain.
Seeds and plants are protected by the basic substance for 7-10 days. Inhibition of the activity of pathogenic fungi manifests itself in the first 3 days after spraying.
Possibility of resistance
If the product is used constantly, then resistance to it in pathogens begins to manifest itself significantly. If you replace the drug with a similar one, the resistance disappears.
Foundationazole has no effect at all on rust fungi and bacteria. The effectiveness of the product against the pathogen of downy mildew is low. Sclerotinia and Alternaria are not affected by benomyl.
Preparation of working solution for different plants
Preparation of the working fluid must take place on a separate site. Water is poured into the spray tank. 5 liters of water are poured into a special container, then the amount of powder is poured into it. After thorough mixing, add water to the required amount. Pour into a spray bottle and spray the plants.
It is necessary to maintain the concentration of the product for different plants. For 10 liters of water take for:
- beets - 6-8 grams of powder;
- wheat, barley, millet - 3-6;
- cabbage - 15;
- dressing of seeds and tubers - 2.5;
- berry bushes - 10;
- flower crops - 10;
- fruit trees - 10 grams.
The consumption of the drug is different for each crop. Usually 5 liters of liquid is enough for young trees and shrubs, and 2 times more for adults.
Instructions for use of the drug
Use a fungicide during watering. The number of treatments varies depending on the crop.
Before planting cabbage, the soil is spilled with working liquid once, saving it from clubroot.
Vegetable plants: cucumbers, tomatoes - are treated when signs of powdery mildew and spotting appear up to 4 times. The last procedure is 10 days before harvest.
Preventive measures with grapes, gooseberry bushes, and currants should be carried out before flowering. The second time - after picking berries.
As soon as spots appear on the rose, the bush requires spraying with Benorad. You can completely get rid of the disease with 4 treatments.
When potato tubers are prepared for planting, they are pickled with a chemical solution, one liter per 20 tubers. The amount of product taken for dilution is 20 grams.
Gladioli bulbs are soaked for 3 hours in a solution prepared from 10 grams of pesticide per 2 liters of water.
Safety precautions when using fungicide
Considering the toxicity of the drug of class 2 for people, you need to work with it only in protective clothing, rubber gloves, a mask, and goggles. It is prohibited to cultivate crops near a river, lake, or pond.
Choose a time for spraying so that there is no flight of bees: morning or evening, and the wind speed is within 3-4 meters per second. The distance to the nearest apiary should be 2 kilometers.
If a person is poisoned by the drug, an ambulance is urgently called. Only systematic treatment will save the patient.
Compatibility with other tools
Benorad is used in tank mixtures with other pesticides and fungicides. It is combined with mineral fertilizers, which are used for foliar feeding.
The effect of the drug increases if it is mixed with products based on triazole and mancozeb.
Expiration date and storage rules
Powder storage must comply with rules and regulations. Store the fungicide in:
- in a special room, separate from animal feed and human food;
- closed container;
- place inaccessible to children and animals.
Spilled or scattered chemicals must be disposed of. It is stored for 2 years.
