棉花枯萎病和黄萎病是我国棉花生产上的严重病害,因其传播途径广、蔓延快,给防治带来极大困难。一旦传入,病情发展迅速,几年内可由零星发病发展到严重发病,个别地块甚至绝产。经多年研究,采用铲除剂消灭零星病点,已是控制田间病害的有效方法。为了广开药源,1981～1985年进行了环氧乙烷副产物铲除棉枯、黄萎病零星病点试验。现总结如下:
Fusarium wilt and Verticillium wilt are the serious diseases in China’s cotton production. Because of its wide spread and rapid spread, it has brought great difficulties in prevention and control. Once introduced, the rapid development of the disease, a few years from a sporadic disease development to a serious incidence of individual plots or even abortion. After years of research, the use of eradication agents to eliminate sporadic disease has been an effective way to control field diseases. In order to widen the source of medicine, 1981 ~ 1985 carried out by-product of ethylene oxide to eliminate cotton withered, Verticillium wilt disease test. Now summarized as follows:
