新型氨基甲酸酯类杀虫剂棉铃威的合成及其杀虫效果

以苄胺、丙烯酸乙酯、一氯化硫、氯化硫酰和灭多威等为原料合成新型氨基甲酸酯类杀虫剂棉铃威,总收率76.7%,产品纯度82.9%。田间药效试验结果表明,棉铃威对棉田棉铃虫和烟草烟青虫有显著杀虫效果,施药7d后300、375、450ga.i./hm2剂量下对棉花棉铃虫的防治效果分别为82.8%、87.9%、94.8%,优于600ga.i./hm2久效灵的效果(61.3%);用量67.5ga.i./hm2对烟青虫的防效在94%以上。

Synthesis and Insecticidal Effect of Novel Carbamate Insecticide Alanycarb

Alanycarb, one kind of novel carbamate insecticides, was synthesized from benzylamine, ethyl crylate,sulphur monochloride and sulfuryl chloride as the raw materials. The total yield and purity of alanycarb was 76.7% and 82.9%,respectively. The field trials results showed that alanycarb had an excellent control of Heliothis armigera Hübner and Heliothis assulta Guenée. The control efficacy was 82.8%,87.9% and 94.8% against Heliothis armigera Hübner at the dosage of 300,375 and 450 g a.i./hm2,respectively,which were better than that of monocrotophos at the dosage of 600 g a.i./hm2,and the control efficacy against Heliothis assulta Guenéee at the dosage of 67.5 g a.i./hm2 was more than 94%.
