摘要
害极灭(AGRIMEC,农业部农药检定所建议商品名为爱力螨克)是链霉菌属一个新菌株所产生的杀虫杀螨素,其杀虫机理是干扰昆虫神经生理活动,抑制神经传导作用而引起死亡。用害极灭1000—2000倍液在蔬菜上防治小菜蛾,10天内防治效果可达到82.07-91.08%,比5%抑太保2000倍的药效好。防治柑桔上的红蜘蛛、锈蜘蛛、潜叶蛾,害极灭3000倍液防治效果达86.2—100%,药效期较长,是值得重视的新型杀虫杀螨农抗。
Agrimec(avermectins)is a natural miticide and insecticide produced by soil
organism Streptomyces avermitilis.It disrupts receptors for aminobutyric acid and
glutamic acid in in the central nervous system and muscular system in insect.1.8% EC
is highly effective(82.07%-91.08%)against Plutella maculipennis ta the concentration
from 18-9 ppm a.i.for duration of 10 days.It is better than IKI-7899,25ppm,Bt
300x and 25% Dimegypo,1000ppm.In the citrus excellect results were obtained
against the Phyllocoptes obleivorus,Panonychus citri and Phyllocnistis citrella.The
