Composition and release form of fungicide "Kurzat"
To protect potatoes, vegetables, and grapes, we need drugs that act locally and systemically. These include the fungicidal agent "Kurzat" from the DuPont Khimprom company.
The composition contains copper oxychloride - 689.5 grams per kilogram of powder. It is this compound that has a fungicidal and bactericidal effect in many preparations approved for use in agriculture against diseases of vegetable crops: potatoes, tomatoes, beets, onions.
To enhance the effect, the product contains cymoxanil, which is especially active against the causative agent of late blight. The substance has a systemic effect against false mealy fungi. Together with copper oxychloride, cymoxanil protects and treats downy mildew on cucumbers in open ground, and the main diseases of potatoes and tomatoes.
The fungicide is produced in the form of a wetting powder. By diluting it with water, a stable suspension is obtained. The powder contains fillers, a dispersant and other additional components that enhance the adhesion of the substance and film formation.
The product is packaged in 5 kilograms per container.
Operating principle and intended use
The action of the main substances when spraying plants:
- creates a protective film on leaves and stems, protecting against penetration of parasitic microorganisms into cells;
- disrupts the processes of mineralization of organic substances;
- suppresses sporulation by suppressing RNA biosynthesis in fungal cells;
- penetrates inside, stopping the spread of the disease.
A feature of the fungicide is that it is active against pathogens that are resistant to other drugs. Farmers use the fungicide for preventive and therapeutic treatments in fields sown with tomatoes, potatoes, and onions.You can also use the working fluid in personal gardens against nightshade late blight and grape mildew.
Advantages of the drug
Many people choose Kurzat because it:
- treats common diseases of garden plants;
- controls sporulation on the underside of the leaf, penetrating deep inside when sprayed;
- actively fights late blight fungus strains that are resistant to other agents;
- low toxicity to humans and bees.
The fungicidal effect lasts for a month after spraying, which is important for summer residents.
How to prepare the solution
Before starting to process the plants, prepare the working fluid. First, take half the amount of water and add the powder. After thorough stirring, add water to the required level. The concentration of active substances depends on the type of disease, the characteristics of its development on vegetables and grapes.
For grapes
The spray liquid is prepared by diluting the powder in a bucket of water. You will need 25-30 grams of the drug. After mixing, the solution is used for its intended purpose. Spray 10 liters of suspension onto 100 square meters.
For tomatoes
The consumption of working fluid for tomatoes will be 5 liters per 100 meters of planting. The concentration of the working fluid is 50 grams per 10 liters of water.
For potatoes
You need to prepare a solution for spraying a potato field before processing. 50 grams of Kurzat fungicide are poured into a bucket of clean water immediately before spraying.
For cucumbers
False powdery mildew on cucumbers can be prevented by treatment in open ground and greenhouse. To do this, prepare a solution by taking 25-30 grams of Kurzat fungicidal powder per 10 liters of water.
For the bow
Pernosporosis also affects beds with onions, and then you can be left without a harvest.Rotting is prevented with a solution of the drug. 60 grams of wetting powder are diluted in 10 liters of clean water.
Instructions for use
Vegetable plantings should be sprayed 3 to 4 times during the growing season with Kurzat. Use working fluid every 10-12 days. The last treatment is carried out 2-3 weeks before harvest, and for grapes - a month.
Pour the prepared solution into a spray bottle or spray bottle. When spraying the suspension, the weather should be clear and calm.
Safety precautions
Working with agrochemicals requires compliance with safety rules. Be sure to wear work clothes, rubber gloves, a respiratory mask, and goggles.
Do not smoke, drink or eat while spraying.
After work, wash your hands with soap. If liquid gets on the skin, carefully remove it with a cotton swab and wash off with soapy warm water.
Toxicity
The fungicide is considered low-hazard to humans and bees. But following the rules for using the chemical will avoid symptoms of poisoning.
Do not pour the remaining solution into water bodies, otherwise fish and amphibians will die. Substances decompose in the ground within 2-6 weeks.
Compatibility with other pesticides
Combine treatment with Kurzat with other fungicides and insecticides. First, substances are checked for compatibility. If they do not combine well, they precipitate in solution. Do not mix copper-containing preparations with alkaline agents or emulsion concentrates.
Terms and conditions of storage of the product
Store the powder in a tightly closed container out of the reach of children and animals. The room temperature should be within 20 degrees Celsius and not fall below 10. Shelf life is 3 years.
Analogs
To make resistance to a fungicide appear less frequently, it is necessary to replace it with other drugs with a similar effect. Agrochemicals such as Bronex, Ordan, and Kuprolux are similar in composition. They are based on copper-containing substances. The products are produced in the form of a wetting powder.
