杀虫制剂复配研究的主要目的在于最大限度地发挥药效,降低毒性,延缓抗性和降低成本。制剂必须无不适气味,不污染环境,不损伤家俱漆膜和衣物等。近年来,国内外对杀虫剂复配日趋重观。在复配的途径和方法上各有不同;例如,荷兰生产的“无比杀虫弹”(Mob—Ⅰ)是胺菊酯与敌敌畏的复配,英国生产的“杀虫威”(Tri-Tox)以天然除虫菊素和敌敌畏复配,这些杀虫剂对小鼠的急性口服LD_(50)为50—100毫克/公斤。既增效又增毒,用于家庭杀虫不安全。日本生产的“ARS”喷射剂以多种拟除虫菊酯加增效剂复配,毒性低,但是被击倒的害虫有复活现象。复配的杀虫
The main purpose of insecticide formulation studies is to maximize efficacy, reduce toxicity, delay resistance and reduce costs. The preparation must have no unpleasant odor, do not pollute the environment, do not damage the furniture film and clothing. In recent years, the compounding of pesticides at home and abroad has been increasing. For example, the “unparalleled insecticide” (Mob-I) produced in the Netherlands is a combination of tetramethrin and dichlorvos. The British-produced Tri-Tox ) Is compounded with natural pyrethrin and dichlorvos. The acute oral LD 50 of these insecticides to mice is 50-100 mg / kg. Both synergistic and toxic, insecticidal insecticide for the family. The “ARS” propellants produced in Japan are complexed with a variety of pyrethrins and booster compounds and have low toxicity, but the pests that have been knocked down are revived.
