粘虫是小麦上主要害虫,常猖獗为害而造成小麦严重减产。过去防治该虫常用敌百虫等药剂,而所用的敌百虫又多为90％晶体敌百虫,在实际使用中,由于溶解慢,使用很不方便。而且在贮藏中由于易吸湿溶解,运输很不安全,有效成分损失严重。为了使用方便,提高药效,延长敌百虫的寿命,除研究敌百虫的混剂外,还可在寻找合理的剂型上找出路,合肥农药厂引进了安徽省化工研究所的技术,已生产出80％敌百虫可溶性粉剂,我们用该药剂防治小麦粘虫,取得显著防治效果,现将试验总结如下。
Armyworms are major pests on wheat and are often rampant and cause severe crop losses. In the past, the insect was commonly used to control trichlorfon and other pesticides, and the trichlorfon used more than 90% crystal trichlorfon, in actual use, due to slow dissolution, the use of very inconvenient. And in the storage due to easy to absorb moisture, transportation is not safe, serious loss of active ingredients. In order to facilitate the use, improve efficacy and extend the life of trichlorfon, in addition to study trichlorfon mixture, but also find a reasonable formulation to find a way out, Hefei Pesticide Factory introduced the Institute of Chemical Technology in Anhui Province, Has produced 80% trichlorfon soluble powder, we use the agent to control wheat armyworms, and achieved significant control effect, the test is summarized as follows.
