Insecticide Abamectin
2022-01-17
Abamectin has stomach poisoning and contact killing effects on mites and insects, but 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, while aminobutyric acid has an inhibitory effect on nerve conduction in arthropods. Adult mites, nymphs and insect larvae appear paralyzed after exposure to abamectin, do not move or feed, and die 2 to 4 days later. Abamectin has a slow lethal effect because it does not cause rapid dehydration of insects. Although Abamectin has direct contact killing effect on predatory insects and parasitic natural enemies, it does little damage to beneficial insects due to less residue on the plant surface. Abamectin is adsorbed by the soil and will not move in the soil, and is decomposed by microorganisms, so it has no accumulation effect in the environment, and can be used as an integral part of comprehensive prevention and control. It is easy to prepare, just pour the preparation into water and stir it for a while, and it is also safer for crops.

poisoning symptoms
Early symptoms are dilated pupils, dyskinesia, and muscle tremors. Usually the patient is highly comatose.
Precautions
[1] Protective measures should be taken when spraying, and masks should be worn.
[2] It is highly toxic to fish and should avoid polluting water sources and ponds.
[3] It is highly toxic to silkworms, and mulberry leaves have obvious effects of poisoning and killing silkworms 40 days after spraying.
[4] Toxic to bees, do not apply during flowering.
[5] The last application was 20 days from the harvest.
Instructions
① To control diamondback moth and cabbage caterpillar, use 1000-1500 times of 2% abamectin EC + 1000 times of 1% emamectin in the young larval stage, which can effectively control their damage, and the control effect on diamondback moth 14 days after the drug It still reaches 90-95%, and the control effect on cabbage caterpillar can reach more than 95%.
② To prevent and control pests such as golden stripe moth, leaf miner, leaf miner, American spotted fly and vegetable whitefly, use 3000-5000 times of 1.8% abamectin EC + 1000 times of egg hatching period and larvae occurrence period High chlorine spray, the control effect is still more than 90% after 7-10 days.
③ To control the beet armyworm, use 1,000 times of 1.8% abamectin EC, and the control effect is still more than 90% after 7-10 days.
④ To control spider mites, gall mites, tea yellow mites and various resistant aphids in fruit trees, vegetables, grains and other crops, use 4000-6000 times of 1.8% abamectin EC spray.
⑤ To control vegetable root-knot nematode disease, use 500 ml per mu, and the control effect is 80-90%.
