遵照毛主席“备战、备荒、为人民”的伟大教导,我们向宁夏化工所等兄弟单位学习,自力更生,奋发图强,利用旧有设备,因陋就简地于七月一日前夕合成出除草剂“敌草腈”纯品——2.6.一二氯苯腈。“敌草腈”是一个应用范围广,有一定选择性的除草剂,对动物毒性很低。据国外资料报导:“敌草腈”能防除禾本科、十字花科、锦葵科、唇形科、旋花科等十余科的大多数杂草,而对大粒种子作物和下种深的作物无伤害。因其蒸气压很高易挥发,还可利用其蒸气抑制窖藏洋芋发芽。在日本, Following Chairman Mao’s great teaching of “Preparing for war, preparing for war and for the people,” we learned from our brothers and colleagues such as Ningxia Chemical Industry Institute to work hard to make good use of old equipment and use the old equipment to produce the herbicide “ ”Pure - 2.6. A dichlorobenzonitrile. “Dimoxifen” is a wide range of applications, a certain selectivity of herbicides, low toxicity to animals. According to foreign data reported: “Dihydrocannabinol” can control most grasses, cruciferae, Malvaceae, Labiatae, Convolvulaceae and other weeds more than ten families, and the seeds of large seeds and seeds under the kind of deep Crops do not hurt. Because of its high vapor pressure easily volatile, but also the use of its steam to inhibit the cellar potato germination. In Japan,
