近年来,我区对果螨的化学防治,存在着农药品种单一、盲目用药和施药量不断加大等问题。而果螨个体小,繁殖快,群体密度大,对单一农药品种产生抗性的周期短;盲目大量施药的结果,大量天敌被杀伤,果螨发生为害更趋严重。为此,我们于1982年在沙依东园艺场梨园和农二师师部果园进行了不同药剂杀螨效果试验。 In recent years, our area of ​​fruit mite chemical control, there is a single species of pesticides, blindly medication and application of increasing dosage and other issues. The fruit mites individual small, fast propagation, population density, a single pesticide variety resistance cycle is short; blind large amount of pesticide application results, a large number of natural enemies were killed, fruit mites occurred more serious damage. To this end, we conducted in 1982 in Shayi east horticultural field orchard and Nong Er Shi Orchard of different agents acaricidal effect test.
