三唑磷是一种高效中,低毒(大白鼠口服LD_(50)为66～82mg/kg,经皮LD_(50)为1100mg/kg)有机磷杀虫、杀螨剂,对人畜毒性明显低于我区目前广泛应用的高毒甲胺磷、1605和稻虫净,加上10年来我区连续大量使用(年用量近1000吨)上述3种农药,不少害虫产生抗性,药效明显降低,因此选用新的中低毒高效农药逐步取代上述农药势在必行。为了加速开发,使三唑磷及早应用于我
Triazophos is a kind of organophosphorus insecticide and acaricidal agent with high and medium and low toxicity (oral administration LD 50 (50 ~ 66mg / kg) and transdermal LD 50 (1100mg / kg) Lower than our district currently widely used highly toxic methamidophos, 1605 and rice pest net, plus 10 years of continuous large-area use in our area (annual consumption of nearly 1,000 tons) of the above three kinds of pesticides, many pests produce resistance Significantly lower, so the selection of new pesticides in the low-toxic and gradually replace the above-mentioned pesticide is imperative. In order to accelerate the development of triazophos so early applied to me
