啶虫脒 性质
新型农药
啶虫脒又名莫司匹林,是一种新型农药,为硝基亚甲基杂环化合物,能作用于昆虫神经系统突触的烟碱型乙酰胆碱受体,干扰昆虫神经系统刺激传导,造成神经通路阻塞,导致神经递质乙酰胆碱在突触处蓄积,使昆虫麻痹,最终死亡。啶虫脒具有触杀、胃毒作用,同时具有渗透力强、易获取、持效期长等特点。
啶虫脒用于防治水稻、蔬菜、果树、茶树上的蚜虫、飞虱、蓟马、鳞翅目等害虫,50~100mg/L浓度下可有效防治蚜虫、蔬菜蚜虫、桃小食心虫,并可杀灭其卵。
理化性质
The original drug acetamiprid is white crystalline. Its content is more than 99%, melting point is 101~103.3℃, and vapor pressure is less than 0.33×10-6Pa (25℃). Acetamiprid is slightly soluble in water, and its solubility in the water is 4.2g/L. Acetamiprid is also soluble in acetone, methanol, ethanol, dichloromethane, chloroform, acetonitrile and the like. It is stable in the neutral or slightly acidic medium, and it can be stored at room temperature for 2 years. It can gradually hydrolyze when pH is 9 at 45℃. It is stable in sunlight.
