Abstract
[Objective]The aim was to screen the effective pesticide to control the occurrence,prevalence and damage of Cnaphalocrocis medinalis.[Method]The control effect of 0.4% chlorantraniliprole GR at different application rates of 30、36、42 g/hm2on Cnaphalocrocis medinalis was studied.[Result]Filed test form 2010 to 2011 showed that the control effect of 0.4% chlorantraniliprole GR at 36 g/hm2on Cnaphalocrocis medinalis reached above 88.00%,and it equivalent to that of chaoranteaniliprole at 200 g/L,and the persistent period was more than 30 days.[Conclusion]0.4% chlorantraniliprole GR at 36 g/hm2was the ideal reagent to control Cnaphalocrocis medinalis,and it was safe to rice.
