摘要
为了明确3种杀虫剂(40%氯虫·噻虫嗪水分散粒剂、34%乙多·甲氧虫悬浮剂和9%甲维·甲虫肼悬浮剂)对水稻二化螟的防治效果,开展了田间试验。结果表明,3种药剂对水稻二化螟的防效均较好。药后14 d,3种药剂对水稻二化螟的防效均在97%以上。药后28 d,9%甲维·甲虫肼悬浮剂对水稻二化螟的防效最高,为90.79%;34%乙多·甲氧虫悬浮剂次之,防效为88.98%;40%氯虫·噻虫嗪水分散粒剂防效为85.80%。3种供试药剂均对水稻生长安全,且对捕食性天敌蜘蛛和黑肩绿盲蝽无明显影响。因此,这3种药剂均可以用于水稻二化螟的防治。
In order to clarify the control effects of three insecticides(40%chlorantraniliprole·thiamethoxam WG,34%spinetoram·methoxyfenozide SC,and 9%emamectin benzoate·methoxyfenozide SC)against rice stem borer,field experiments were conducted.The results showed that all the three insecticides had good control effects on the rice stem borer.On the 14th day after treatment,the control effects of the three insecticides were all above 97%.On the 28th day after treatment,the control effect of 9%emamectin benzoate·methoxyfenozide SC against rice stem borer was the highest(90.79%),followed by 34%spinetoram·methoxyfenozide SC(88.98%),the control effect of 40%chlorantraniliprole·thiamethoxam WG was 85.80%.The three insecticides were safe for rice growth,and had no obvious effect on predatory natural enemies such as spider and green miridae.Therefore,the three insecticides can be used to control rice stem borer.
