15％茚虫威添加有机硅助剂防治稻纵卷叶螟田间药效试验

Field efficacy of indoxacarb 15% SC added organosilicone surfactants in controlling rice leaf-roller

为了解农用有机硅助剂添加在杀虫剂上的效果，于2009年6月进行了15％茚虫威悬浮剂添加有机硅助剂防治稻纵卷叶螟田间药效试验。结果显示，150～300mL／ha15％茚虫威悬浮剂添加有机硅助剂处理对稻纵卷叶螟有较好的防治效果，且对水稻安全，与不添加有机硅助剂处理的防效差异达极显著水平。综合几种处理的防治效果以及经济效益分析，生产上以在稻纵卷叶螟1—3龄幼虫期每公顷使用150～225mL15％茚虫威悬浮剂，同时添；~D225mL有机硅助剂对稻纵卷叶螟的防治效果最好。

Experiment on efficacy test of indoxacarb 15% SC added organosilicone surfactants in controlling rice leaf-roller was undertaken in June 2009 to study the effect of pesticide added agricultural silicone emulsion. The results revealed that 150~300 mL/ha indoxacarb 15% SC added organosilieone surfactants had good controlling effeet on rice leaf- roller, it was safe and had very significant difference with indoxacarb without organosilicone surfaetants in it. As a whole, it was best for the prevention and cure of rice leaf-roller during 2-3 instar larvae. Use of 150~225 mL/ha indoxacarb 15% SC with 225 mL organosilicone surfactants together gave good results.
