45%胶敌磷是苏州化工厂生产的复配农药。1985年以来的多点重复试验结果,药效快,残留少,弥补了甲胺磷与敌敌畏的弱点,是稻田较为理想的广谱、高效杀虫剂。一、防治稻纵卷叶螟、稻飞虱的效果胺敌磷防治稻纵卷叶螟、稻飞虱,以50%甲胺磷为对照药剂,分别设置每亩0.15斤对水120斤喷雾,0.20斤掺潮细土50斤撒毒土,及其空白对照,五个处理。试验结果,防治稻纵卷叶螟,药剂处理区防治效果都
45% plastic enemy phosphorous is a compound pesticide produced in Suzhou Chemical Plant. Repeated test results since 1985, more rapid, less residue, made up for the weakness of methamidophos and dichlorvos, rice is more ideal broad-spectrum, high-performance insecticide. First, the prevention and control of rice leaf roller, the effect of rice planthopper Amine phosphorus prevention and control of rice leafroller, planthoppers to 50% methamidophos as a control agent, respectively, set 0.15 kg per mu of 120 kg of water spray, 0.20 kg mixed with 50 pounds of fine soil sprinkle soil, and its blank control, five treatment.
