Avermectin has stomach toxicity and contact killing effect on mites and insects, and cannot kill eggs. The mechanism of action is different from that of general insecticides in that it interferes with neurophysiological activities and stimulates the release of γ-aminobutyric acid, which has an inhibitory effect on nerve conduction in arthropods. Adult mites, nymphs and insect larvae appear paralyzed after contact with avermectin, do not move, do not eat, and die after 2~4 days. Because it does not cause rapid dehydration of insects, avermectin has a slower lethal effect. Although avermectin has a direct contact killing effect on predatory insects and parasitic natural enemies, it has little damage to beneficial insects because of the small residue on the surface of plants. Abamectin is adsorbed by the soil and does not move, and is decomposed by microorganisms, so there is no accumulation in the environment, and it can be used as an integral part of comprehensive control. It is easy to prepare, pour the preparation into the water and stir it slightly, and it is also safer for crops, and it will not cause pesticide damage when used according to the introduced method. Suitable for crops: vegetables, citrus, cotton, etc. Control object: There are special effects for resistant pests, such as diamondback moth, leaf miner, red spider, etc. Application technology: avermectin has stomach toxicity and contact killing effect on mites and insects, strong permeability, the liquid medicine sprays into the leaf surface of the plant and quickly penetrates into the mesophyll to form numerous miniature sacs, the adults of mites, nymphs and larvae of insects eat and contact with the liquid immediately after the paralysis symptoms, inactivity, do not eat, 2~4 days after death. Avermectin has very little residue on the foliar surface and is quickly decomposed into non-toxic substances, so it is less lethal to natural enemies. Avermectin has no eggicidal effect. Abamectin is used to control mites, such as red spiders and rust spiders, with 1.8% avermectin 3000~5000 times liquid or 1.8% avermectin 20~33 ml per 100 liters of water (effective concentration 3.6~6 mg/L). For the prevention and control of lepidopteran insect larvae such as diamondback moth, spray with 1.8% avermectin 2000~3000 times or 1.8% avermectin 33~50 ml per 100 liters of water (effective concentration 6~9 mg/L). The effect of the pesticide is best when the larvae hatch at the beginning, and the addition of a dry part of vegetable oil can improve the efficacy.
