灭蚜硫磷

灭蚜硫磷用途

氨基甲酸酯类内吸性杀虫剂，胆碱酯酶抑制剂。分子结构中含三唑基团，是广谱、高效、高选择性的杀蚜药剂，对抗性蚜虫也有良好的防效。由于该药剂能在作物脉管中形成上、下双相传导，因此土壤用药可防治食叶性蚜虫，而叶面喷施可防治食根性蚜虫，从而保护整个植株。推荐用药量为0.6～0.9g有效成分/100m²，防治抗性蚜虫及棉蚜需0.9～1.5/100m²，防治伏蚜需1.8～2.3g/100m²。药剂持效期长达10～15d。

灭蚜硫磷制备

3-特丁基-5-巯基-1，2，4-三唑的制备 2，2-二甲基丙酰氯与氨基硫脲作用，生成酰化氨基硫脲，再用氢氧化钠水溶液处理，环合生成3-特丁基-5-巯基-1，2，4-三唑。
唑蚜威的合成 3-特丁基-5-巯基-1，2，4-三唑与氯乙酸乙酯反应后，再与二甲基氨基甲酰氯反应合成唑蚜威。
