易卫杀属沙蚕毒系新杀虫剂,经多次试验,对水稻二化螟、三化螟、稻纵卷叶螟、稻苞虫等有很强的杀虫效果,对稻飞虱,稻叶蝉等也有一定的防效。为了解此药在水稻上的残留状况,1981~1982年进行了田间使药后的残留量测定。 供试药剂,1981年为33.37%易卫杀粉剂(贵州省化工研究所),1982年为35%易卫杀粉剂(山东德州农药厂)。用100%易卫杀标样(南开大学元素所)和94%易卫杀标样(贵州省化工研究所)。
Yi-Wei kill neotythium toxicity of the new pesticides, after many tests, the rice borer, Borer, rice leaf roller, rice insects and other insects have a strong insecticidal effect on planthoppers , Rice leafhoppers, etc. also have some control effect. In order to know the residue status of this medicine on rice, the residual amount after the medicine in the field was measured from 1981 to 1982. Test agents, in 1981 was 33.37% Yi Wei powder (Guizhou Institute of Chemical Industry), in 1982 to 35% Yi Wei powder (Shandong Texas pesticide plant). 100% easy to kill standard samples (Nankai University Institute) and 94% easy to kill standard (Guizhou Institute of Chemical Industry).
