5%多杀霉素·甲氨基阿维菌素苯甲酸盐油悬浮剂防治稻纵卷叶螟效果田间试验

Control Test of 5% Spinosad·Emamectin Benzoate OF against Rice Leaf Roller

为了探讨5%多杀霉素.甲氨基阿维菌素苯甲酸盐油悬浮剂对稻纵卷叶螟的防效和使用技术,采用300 mL/hm2、450 mL/hm2和600 mL/hm23种不同浓度处理进行稻纵卷叶螟防治效果比较试验。结果表明:5%多杀霉素.甲氨基阿维菌素苯甲酸盐油悬浮剂对稻纵卷叶螟具有较好的防效,其中用药600 mL/hm2在2011年和2012年的防效分别为82.76%和84.61%。

In order to discuss control effect and operation technology of 5% Spinosad. Emamectin benzoate OF against rice leaf roller, 3 different eoncemtration treaments of 300 mL/hm2,450 mL/hm2 and 600 mL/hmz were used to study control effect on rice leaf roller. The result showed that 5% Spinosad. Emamectin benzoate OF had better control effect, control effect of 600 mL/hm2 were 82.76% and 84,61% respectively in 2011 and 2012.
