溴虫腈与虫酰肼以五种比例复配,经室内对甜菜夜蛾的毒力测定,溴虫腈对甜菜夜蛾的毒力较高,48h的LC50为27.2030mg/L。其优选配方(v∶v=1～2∶1)的共毒系数达219.9～254.1,增效作用明显。
Chlorfenapyr was mixed with tebufenozide in five proportions. The indoor toxicity to beet armyworm was determined. The toxicity of chlorfenapyr to beet armyworm was high. The LC50 value at 48h was 27.2030mg / L. Its preferred formulation (v: v = 1 ~ 2: 1) of the co-toxicity coefficient of 219.9 ~ 254.1, synergistic effect.
