Instructions for use of the fungicide Acrobat and the mechanism of action
Diseases of plants delay the development of garden and horticultural crops, reduce productivity. Therefore, the summer resident needs to know what means to fight against pathogenic microorganisms that have a negative effect on the growth of crops, destroying them. Among the fungicides "Acrobat", the instructions for the use of which are often used by gardeners, occupies a leading place.
Composition and form of release "Acrobat MC"
The manufacturer of pesticides BASF has released a drug, the main components of which are actively fighting pathogens, penetrating inside and disrupting the biochemical processes of the microorganism. The group of dithiocarbamates is represented by the substance mancozeb. Its in the preparation is 600 grams per kilogram of product.
In combination with mancozeb in the "Acrobat", the active ingredient is dimethomorph (90 grams / kg), which belongs to the chemical group of morpholines. A phenalamide derivative changes the development cycle of a pathogenic fungus.
The formulation of the fungicide is water-dispersible granules. When dissolved, a homogeneous suspension is obtained.
Granules are packaged in packages of 1 kilogram, bags - 10 kilograms.
Mechanism of action
The combination of 2 components leads to the death of fungi, spores, stopping the subsequent reproduction of microorganisms. After processing, the active substances penetrate into the plant cells, and also remain on the surface.
The substance mancozeb from the dithiocarbamite group suppresses the activity of enzymes inside microorganisms. As a result, their breathing becomes difficult, the most important redox processes stop.
The toxic effect of the substance is associated with the disruption and exchange of biogenic amino acids.
Dimetamorph penetrates the cell membranes of the pathogen, preventing the formation of mycelium, disrupting the development cycle of the microorganism. At the same time, new populations of fungi resistant to morpholines are formed more slowly.
Advantages over analogues
The advantages of the fungicide "Acrobat MC" include the fact that it acts:
- as a preventive and therapeutic agent;
- not allowing new disputes to arise;
- without poisoning the environment, insects, humans;
- effective in combination with other fungicidal preparations.
There are no restrictions on the use of granules. Although there are more effective analogues, they quickly become addictive. Resistance to "Acrobat" develops more slowly in fungi.
Preparation of working solution and its application
They choose clear, windless weather for processing plants. This will allow the solution to adhere evenly to the leaves and stems, protecting them from fungus.
In a special container, dissolve 20 grams of the product in 5 liters of water. Applying the drug at the beginning of the season, they create protection for potatoes, tomatoes, grapes from fungal infection.
Grape processing
Planting vines must be treated with a mildew preparation three times per season. The interval between spraying is 20 days.
Potatoes
Spraying with a fungicide is carried out as a preventive measure. But the appearance of signs of late blight, alternaria requires treatment with "Acrobat". Necessarily need three spraying with a break of 15-20 days.
Tomatoes
During the growing season, tomatoes must also be processed three times. For 100 square meters, you will need 4 liters of working solution. After spraying, it is undesirable to work with plants.
Cucumbers
To protect the beds with cucumbers from downy mildew is also necessary with the preparation "Acrobat". The working solution is sprayed on plants in clear weather in the morning or in the evening when there is no wind. The frequency of spraying is 3-5 times.
Drug toxicity, safety precautions
The drug "Acrobat MC" belongs to the 2nd class of danger to humans. This means that it is necessary to spray it, prepare the working fluid in a respiratory mask, work clothes, protect your hands with rubber gloves, and protect your eyes with glasses.
After treatment, you should wash your hands with soap, take a shower, rinse your mouth.
The last spraying is carried out 1.5 months before harvest. And after spraying, you cannot work in the vegetable garden and garden for 10-15 days.
For bees, the drug is of little danger, but it is better to use it when the insect years are limited. The fungicide does not harm earthworms.
Is it compatible with other products
You can independently determine the compatibility of Acrobat with other fungicides and insecticides. To do this, a small amount of granules is mixed with other preparations, stirred. If the precipitate does not dissolve, then the funds cannot be used together.
Shelf life and storage conditions
For storage of granules, a special room is used, inaccessible to pets and children. The container must be tightly closed. When a substance is combined with oxygen, an explosion can occur. The temperature in the room must not be above 20 degrees.
The shelf life of the fungicide is 2 years from the date of release of the product.
Similar means
Contact-systemic drugs are similar in action to "Acrobat":
- Ridomil Gold;
- Oxyhom;
- "Cabrio TOP".
Fungicides are used for prevention and treatment. They have a detrimental effect on parasites belonging to the Oomycetes.
