柑桔红蜘蛛为害严重,是影响柑桔生长的主要原因之一。目前市场上杀螨剂多不理想,国外进口的杀螨剂如倍乐霸、霸螨灵、速螨酮等对成螨、若螨和卵虽有良好的效果,但价格较贵,而尼索朗杀螨剂,红蜘蛛对之已产生抗药性。国内的三氯杀螨醇、水胺硫磷等杀螨剂,又无杀卵作用,且有效期短,加上常年使用,也已产生了抗药性。因此,我们开展了三唑磷乳油的防治研究,探讨其效果。该农药是一种高效、广谱的有机磷杀虫、杀螨剂,对柑桔红蜘蛛有良好的防治效果。 试验方法 供试农药包括:20％三唑磷乳油500倍液（宁化县生物有机化学厂生产）;20％三氯杀螨醇乳油1000倍液（建瓯化工厂生产）;5％尼索 Citrus spider mite damage is one of the main factors affecting the growth of citrus. Acaricides currently on the market more than ideal, imported acaricides such as Pa Pa, Pa muling spirit, speed mites and other adult mites, if mites and eggs, although good results, but the price is more expensive, and Nigeria Sorang miticide, red spider has been resistant to them. The domestic dicofol, acetoside and other acaricide, but also no egg killing effect, and the short duration, coupled with perennial use, but also has produced resistance. Therefore, we conducted a triazophos EC control study to explore its effectiveness. The pesticide is an efficient and broad-spectrum organophosphate insecticide and acaricide which has good control effect on citrus red spider. Test methods Test pesticides include: 20% triazophos EC 500 times (Ninghua County Biological Organic Chemical Plant production); 20% dicofol EC 1000 times (Jian Chemical Plant); 5% Nisuo
