水稻二化螟防治药剂筛选试验
The Agents Screening Test of Chilo suppressalis
摘要
Abstract
In view of the current high-level resistance of Chilo suppressalis to traditional insecticides and its harm in rice production,this study selected 9 kinds of commonly used insecticides for the control of Chilo suppressalis,and screened out efficient new insecti-cides to replace traditional insecticides through field efficacy test,so as to comprehensively improve the control level of Chilo suppres-salis.The results showed that 10％cyclopropyl fipronil and 2％chlorantraniliprole+32％monosultap showed higher control effect and longer efficacy duration in the control of Chilo suppressalis,with the highest control effect of 94.7％and 93.1％,and the comprehen-sive control effect was the best.The control effects of 10％chlorantraniliprole and 9％chlorantraniliprole+2.6％Emamectin salt SC respectively reached 87.8％and 85.7％.However,there were significant differences in the performance under different application time,which may be related to the chemical composition,mechanism of action and environmental factors,and need to be further veri-fied.The comprehensive control effect of other pesticides was poor,and the lowest was only 4.9％.In conclusion,the control effect of 10％cyfluthrin and 2％chlorantraniliprole+32％monosultap is outstanding,and the efficacy duration is long,so the author suggests giving priority to the use in actual production.关键词
