田间试验表明 ,新氨基甲酸酯杀虫剂杀虫威对鳞翅目害虫棉铃虫、菜青虫、烟青虫防治效果优良。杀虫威 2 0 %EC在河南防治 2代棉铃虫使用剂量 1 0g (a.i.) 667m2 药后 2～ 7d ,校正防效为90 65 %～ 97 72 % ,在山东药后 3～ 5d ,防效为 85 1 7%～ 91 2 3 % ,7 5g (a .i.) 667m2 相应药效两地分别为 88 41 %～ 95 2 7%和 81 40 %～ 85 61 % ;防治 3代棉铃虫使用剂量 2 0g (a.i.) 667m2 药后 2～ 5d ,防效两地分别为 83 93 %～ 86 1 5 %和 85 5 3 %～ 88 2 9% ,1 5g (a .i.) 667m2 相应药效分别为 77 66%～80 2 3 %和 78 5 0 %～ 83 75 %。防治烟青虫使用剂量 1 0g (a.i.) 667m2 药后 3～ 7d校正防效为 85 5 7%～ 88 2 9% ,7 5g (a .i.) 667m2 相应药效为 81 5 1 %～ 86 1 1 %。防治菜青虫使用剂量 7 5～ 1 0g (a .i.) 667m2 药后 3～ 7d防效为 87 5 0 %～ 96 1 1 %。
Field trials showed that the new carbamate insecticide insecticide on Lepidoptera bollworm, Pieris rapae, tobacco budworm control effect. Insecticide 20% EC in Henan control two generations of cotton bollworm use dose 10g (ai) 667m2 medicine 2 ~ 7d, the corrected effect of 90 65% ~ 97 72%, 3 ~ 5d after Shandong medicine, anti-efficacy The results showed that the relative efficacies of 881% -95 2 7% and 81 40% -85 61% for 857% ~ 91 2 3% and 757% After the dose of 20g (ai) and 667m2 for 2 ~ 5d, the control efficacies were 83 93% ~ 86 1 5% and 85 5 3% ~ 88 2 9%, respectively. Respectively 77 66% ~ 80 2 3% and 78 5 0% ~ 83 75%. The results showed that the control efficacy against tobacco budworm was 85 5 7% ~ 88 2 9% after 3 ~ 7 d of 667m 2 dosage of 100g (ai) 667m 2 and 81 5 1% ~ 86 1 for 7 5g 1 %. Control Pieris rapae dosage 7 5 ~ 1 0g (a .i.) 667m2 3 ~ 7d after the drug control effect was 87 5 0% ~ 96 1 1%.
