Avermectins are a class of substances that are used for the manufacture of insecticidal and acaricidal preparations for use in agriculture. Let's consider the action and properties of aversectin, what products it is contained in, how and why to use it according to the instructions. What drugs are compatible with aversectin, how and for how long to store them.
Physical and chemical properties
Aversectin acts as an insecticide, acaricide and nematicide, therefore it is included as an active substance in agricultural biological preparations for the destruction of pests - insects, mites, nematodes.It has several varieties: aversectin s, aversect-2, pharmacin, unitar. Aversectin C is a natural mixture of 4 avermectins - B1a, A1a, A2a, B2a, which are produced by microorganisms of the Streptomyces avermectilis variety.
Pure substance looks like whiteThis powder with a characteristic odor is produced for the production of drugs in emulsion concentrates of 2% and 10%. It has an intestinal and contact effect on pests. Products containing it are used by spraying.
Effect on harmful organisms
The substance enters the pests by being absorbed through the outer coverings, or gets inside when insects eat leaves treated with the solution. Aversectin paralyzes pests, followed by their death. First, the insects stop feeding (within 8-10 hours after treatment) and die within 3-6 days. The protective effect lasts 3 weeks. Pests do not become accustomed to aversectin; products containing it can be used for several years in a row.
What drugs does it contain?
Aversectin is the active substance of Fitoverma, AltAlfa, Actofita, Stimpo. The preparations can be used both in agricultural fields and gardens for the treatment of plantings on a large scale, and in private farms. They are effective against leaf-eating and leaf-sucking species; there are products with aversectin for treating farm animals against ecto- and endoparasites.
Instructions for use
Biological products that include aversectin are non-toxic to people, animals, insects, soil and plants. They are used against pests of fruits, vegetables, ornamental crops, and flowers grown indoors.
The toxicity of products containing aversectin varies greatly under the influence of temperature.When decreasing from 24 to 17 °C, the effect on spider mites decreases by 7.6 times, but increases by 4.8 times at temperatures up to 32 °C. As for the harmfulness of the substance to plants, it disappears in their leaves already 2-3 days after spraying, in vegetables – on the 2nd day. The waiting period is short - only 1-3 days. It does not penetrate into plants through the root system.
Aversectin decomposes quickly: it half-disintegrates in water in 3 days, in the ground in greenhouse conditions - in 25-30 hours. Preparations with aversectin can be used in fields, street beds, and greenhouses.
Security measures
The substance is not dangerous for humans; agricultural products belong to class 3 toxicity. For bees - to grades 2 and 3. When working with drugs, be sure to wear thick clothing with long sleeves so that it covers open parts of the body that the solution may come into contact with. You can protect your eyes with transparent plastic glasses and your hands with rubber gloves.
After completing the treatment, you need to wash your face and hands with soap and rinse areas of the skin that may have been exposed to the solution. If liquid gets into the stomach, you need to rinse: drink 1 liter of clean water and take 6 or 7 tablets of activated carbon.
Compatibility
Products containing aversectin can be mixed with chemicals. insecticides, such as pyrethroids. Moreover, the effectiveness of both drugs increases, the rate of use is reduced by half, and the waiting time for action is reduced.
According to the manufacturer's recommendation, when mixing with other pesticides, the interaction should be checked by mixing a small volume of the drugs in a separate container.If no reaction occurs, the substances are compatible. If a chemical reaction occurs, they should not be mixed.
Storage rules
Products containing aversectin can be stored for 2 years without loss of beneficial properties, provided that the conservation rules are followed. All pesticides should be stored only in original packaging with screwed caps. Storage conditions: dark, dry, shaded and ventilated area. Temperature – 0-30 °C. Do not place food, medicines, or pet food nearby. After the expiration date, any remaining medications should be thrown away.
Fresh solution must be consumed on the day of preparation; it is not stored longer than 1 day.
Aversectin is the active substance of pesticides from the avermectin class. Products containing it are used in agriculture and on personal plots for the treatment of fruit, vegetable, berry and flower plants. Destroys various types of insects, mites, nematodes. Since this is a biological product, it is not as effective as chemical ones, so it is necessary to spray the crops at least 2-3 times. But the waiting period for such products is short; you can safely use them on fruit-bearing plants and harvest the fruits a maximum of 3 days after spraying.
It is precisely this property of biological products that makes them convenient for use on tomatoes, cucumbers, peppers, shrubs and fruit trees, where harvesting is necessary frequently. There is no need to wait long for the fruits to become safe. After spraying, the protective effect remains for 3 weeks, which is a good indicator for a biological product. Then you can carry out another spraying.
