乙唑螨腈对豇豆二斑叶螨的防治效果评价

摘要

This paper investigated the growing and declining law of Tetranychus urticae Koch in Bole City of Xinjiang Autonomous Region,and studied the effect of SYP-9625 against Tetranychus urticae Koch. The results indicated that Tetranychus urticae Koch in Bole City started to damage cowpea since mid July. The peak time would last until September 10th. On mid July,spraying 30% SYP-9625 SC 4 000 times + organosilicon assistant to control Tetranychus urticae Koch is a new method. This method has fast-acting property and long-lasting effect in controlling Tetranychus urticae Koch. And it is also safer for cowpea growth.%对新疆博州地区豇豆二斑叶螨田间消长规律进行调查,并研究乙唑螨腈对二斑叶螨的防治效果.结果表明:7月中旬博州二斑叶螨在豇豆上开始发生为害,高峰时期一直持续到9月10日.7月中旬施用1次30%乙唑螨腈悬浮剂4 000倍液+有机硅助剂防治豇豆二斑叶螨,速效性好、持效期长,且对豇豆安全.
