应用有机磷浸种拌种防治蝼蛄,不用粮食作饵料是目前农业生产上的迫切要求。1964年春聊城专区农业科学研究所用1605、敌敌畏、乐果、敌百虫等有机磷浸种拌种防治春谷蝼蛄作了保苗效果的试验,现将试验结果介绍于下,供参考。一、试验材料和方法: 供试药剂:50%1605乳剂(德国拜耳药厂出品),6%可湿性666(张店农药厂出品),50%敌敌畏(天津农药厂出品),90%敌百虫及乐果乳剂(均系上海农药厂出品)。试验地选择蝼蛄基数较高的地块,随机区组法,重复三次(苗期防治试验重复两次)。小区
Application of organic phosphorus seed dressing seed dressing prevention and control, without food for food is an urgent requirement of agricultural production. Spring 1964 Liaocheng Prefecture Institute of Agricultural Sciences with 1605, dichlorvos, dimethoate, trichlorfon and other organic phosphorus soaking seed dressing seedlings prevention and cure Spring Valley seedling effect test, the test results are introduced below, for reference. First, the test materials and methods: Test agents: 50% 1605 emulsion (Germany Bayer pharmaceutical production), 6% wettability 666 (Zhangdian Pesticide Factory produced), 50% dichlorvos (Tianjin Pesticide Factory produced), 90% Pest and dimethoate emulsion (all produced by Shanghai Pesticide Factory). Experimental plots to choose the highest base 蝼,, randomized block method, repeated three times (seedling control test repeated twice). Community
