阿维菌素不同剂型对果树害虫田间控制效果比较

为明确阿维菌素不同剂型对苹果主要害螨控制作用之间的差异，本研究以1.2%阿维菌素微胶囊水悬剂、1.8%阿维菌素可湿性粉剂、1.8%阿维菌素微乳剂、1.8%阿维菌素乳油为代表品种，参照农药田间药效试验准则，针对苹果全爪螨（Panonychus ulmi Koch)和二斑叶螨（Tetranychus urticae Koch)开展田间药效对比试验，比较阿维菌素在相同有效成分下不同剂型的防效差异。结果表明：微乳剂与乳油相比，对靶标生物的各期防效差异不大；而微囊悬浮剂和可湿性粉剂与乳油相比，其速效性和持效性均不及乳油。从生态学和经济学的角度考虑，微乳剂是阿维菌素今后剂型加工的方向之一。

Comparison among different forms of abamectin on controlling fruit pests

To investigate the difference between different forms of abamectin on controlling fruit mite,with reference of pesticide－guidelines for the field efficacytrials,the effects of 1.2% abamectin CS、1.8% abamectin WP、1.8% abamectin ME and 1.8% abamectin EC (with the same content of functional component) on controlling Panonychus ulmi Koch and Tetranychus urticae Koch were compared by field trail.The results show: there is no much difference between ME and EC on controlling the target insects in different stage; the quick-acting effects of EC is better than CS and WP.In view of ecology ang economice, micro-emulsion is a new develop direction for the future.
