Avermectin is a widely used agricultural or veterinary insecticide and acaricide . Avermectin is the most popular and highly competitive new product in the current biopesticide market. "What reason is lack of avermectin acaricidal capacity" is the question many farmers, following China pesticide Xiaobian explain this issue as follows.
Avermectin is a natural fungus. Avermectin is a typical biological pesticide and is not a chemical pesticide. The mechanism of Averm is to infect the insects and destroy their digestive system, leading to their eventual death (longer duration). There are few residues of Avicin. If it is used in the early stage, it will not be monitored at all, and it will not be found at all.
Any kind of pesticide will produce resistance after repeated use. Abamectin will also develop resistance after repeated use. Therefore, when using pesticides to control aphids, it is necessary to select pesticides with high resistance to chemicals.
The characteristics of avermectin:
Abamectin has stomach poisoning and contact killing on mites and insects and cannot kill eggs. The mechanism of action differs from that of general insecticides in that it interferes with neurophysiological activities and stimulates the release of gamma-aminobutyric acid, which inhibits the nerve conduction of arthropods. When mites, nymphs and insect larvae come into contact with avermectin, paralysis symptoms appear, inactivity, no feeding, and death after 2 to 4 days. The avermectin lethal effect is slower because it does not cause rapid dehydration of insects. Although avermectin has direct contact and killing effect on predatory insects and parasitic natural enemies, it has little damage to beneficial insects due to less residual surface of plants. Abamectin is not adsorbed by soil in the soil and is decomposed by microorganisms, so it has no cumulative effect in the environment and can be used as an integral part of comprehensive control. It is easy to prepare, and the preparation can be used by pouring it into water and stirring it, which is safe for crops.
Tips for the Chinese pesticide network Xiaobian: protective measures should be taken when applying the medicine , and masks should be worn to prevent avermectin poisoning.
