用途:阿维菌素对螨类和昆虫具有胃毒和触杀作用，不能杀卵。作用机制与一般杀虫剂不同的是干扰神经活动，刺激释放γ-氨基丁酸，而氨基丁酸对节肢动物的神经传导有抑制作用。螨类成虫、若虫和昆虫幼虫与阿维菌素接触后即出现麻痹症状，不活动、不取食，2～4天后死亡。因不引起昆虫迅速脱水，所以阿维菌素致死作用较缓慢。阿维菌素对捕食性昆虫和寄生天敌虽有直接触杀作用，但因植物表面残留少，因此对益虫的损伤很小。阿维菌素在土内被土壤吸附不会移动，并且被微生物分解，因而在环境中无累积作用，可以作为综合防治的一个组成部分。调制容易，将制剂倒入水中稍加搅拌即可使用，对作物亦较安全。

Abamectin: Abamectin Chinese alias: Abamectin, Abamectin CAS landing number: 71751-41-2 appearance: white or yellowish crystal powder content: 95% molecular formula: C48H72O14 (B1a). C47H70O14 (B1b) molecular weight: 873.09 Uses: Abamectin has stomach toxicity ａnd touch killing effect on mites ａnd insects, can not kill eggs. Different from other insecticides, the mechanism of action is to interfere with nerve activity ａnd stimulate the release of gamma-aminobutyric acid. Aminobutyric acid can inhibit nerve conduction in arthropods. Adults, nymphs ａnd larvae of mites were paralysed immediately after contact with avermectin. They were inactive ａnd did not feed. They died 2 to 4 days later. Avermectin has a slow lethal effect because it does not cause rapid dehydration of insects. Avermectin has a direct contact killing effect on predatory insects ａnd parasitic natural enemies, but it has little damage to beneficial insects because of less residue on plant surface. Avermectin can not be absorbed by soil ａnd decomposed by microorganisms, so it has no cumulative effect in the environment ａnd can be used as an integral part of integrated control. The preparation is easy to prepare, ａnd can be used by pouring the preparation into water with a little stirring. It is also safer for crops. Packaging: 25kg/cardboard drum;
