麦田杂草以麦蒿、荠菜、唐介为主的,用2甲4氯除草效果好。而对鹅不食草、泽漆、尼糊菜、王不留行和麦蒿、荠菜、唐介的混生杂草的麦田用2甲4氯防除效果则差。为了提高混生麦田杂草的防除效果,近年来我们对三种除草剂进行单用、混用的除草试验,收到较好的效果。现将试验结果简结如下。一、试验材料和方法 (一)供试药剂 56％ 2甲4氯钠盐(抚顺农药厂)、48％麦草畏(美国贝尔西可公司)、72％2,4-滴丁酯(沈阳军区旅大化工厂)
Wheat weeds to Mai Hao, shepherd’s purse, Tang mediated mainly with 2 A 4 chlorine weed effect. The goose does not eat grass, Ze lacquer, Nepalese dish, Wang Buyuhang and wheat straw, shepherd’s purse, Tang mediated mixed weed wheat with 2 A 4 chlorine control effect is poor. In order to improve the control effects of weeds in mixed wheat fields, we conducted single-weeding and mixed weeding experiments with three kinds of herbicides in recent years and received good results. The test results are summarized below. First, the test materials and methods (a) for the test agent 56% 2 A 4 chlorine sodium salt (Fushun Pesticide Factory), 48% dicamba (the United States Bell Corp.), 72% 2,4-D butyl ester (Shenyang Military Region Luda Chemical Factory)
