摘要
[目的]明确12种常用水稻稻飞虱防治药剂的防治效果。[方法]选取目前使用较多的12种水稻稻飞虱药剂,采用随机区组设计,开展田间防治效果试验。[结果]参试的12种防治药剂在推荐剂量下对水稻稻飞虱均有较好的防治效果,药后14 d对水稻稻飞虱防效在86.11%～93.22%,其中10%烯啶虫胺水剂、50%吡蚜酮·异丙威可湿性粉剂、80%吡蚜酮·噻虫嗪水分散粒剂、25%噻虫嗪水分散粒剂4种药剂对稻飞虱药后3 d防效均在80%以上,药后14 d防效在90%以上。[结论]10%烯啶虫胺水剂、50%吡蚜酮·异丙威可湿性粉剂、80%吡蚜酮·噻虫嗪水分散粒剂、25%噻虫嗪水分散粒剂有较好的速效性和持效性,对稻飞虱防治效果较好。
[Objective]12 kinds of pesticides were investigated in field experiments to comprehend the effect of controlling rice planthopper.[Method]The field experiments for control effect of 12 kinds of pesticides on rice planthopper were finished by randomized block design,in Shouxian County Anhui Province.[Result]12 kinds of pesticides with recommended dose on rice planthopper had satisfactory control effect,between 86.11%-93.22%after 14 days.The control effect of 4 pesticides,including 10%acetamide SL,50%pyridazone-isoprocarb WP,80%pyridazone-thiamethoxazine WG and 25%thiamethoxazine WG,on rice planthopper were above 80%after 3 days and 90%after 14 days.[Conclusion]10%acetamide SL,50%pyridazone-isoprocarb WP,80%pyridazone-thiamethoxazine WG and 25%thiamethoxazine WG had obvious efficacy and sustainability,and had strong control effect on rice planthopper.
