| Abstract: | Field control efficiency of 5 kinds of insecticides on larvae of Spodoptera exigua Hubner was evaluated.The results showed that chlorfenapyr 10% SC had best rapid and durable effect among 5 kinds of insecticides,with 96.76% and 97.93% control efficacies on the first and 7th days after treatment,respectively.While avermectin 18 g/L EC had bad rapid available and general durable effect,with 27.18% and 87.02%.Chlorpyrifos 48% EC,emamectin-benzoate 3%WG and chlorantraniliprole 20% SC also had good rapid and durable effect,the control efficacies of these insecticides on the first and 7th days after treatment were above 60% and 85%,respectively. |
