| Abstract: | Objective] The research aimed to study the control efficiency of 3% beta-cyfluthrin and emamectin benzoate EC on P.xylostella.Method] 3% beta-cyfluthrin and emamectin benzoate were mixed by different proportion,and then studied their toxicity to P.xylostella.Result] The co-toxicity coefficient was 124.78 when the mixed proportion of 3% beta-cyfluthrin and emamectin benzoate was 2.0∶1.0,showed synergy.And its LC50 value to P.xylostella larvae was 17.21 mg/L,showed strong toxic effect on P.xylostella larvae.Conclusion] The EC of 3% beta-cyfluthrin and emamectin benzoate 2.0∶1.0 has good control efficiency on P.xylostella. |
