温州市近年来因农田管理粗放,杂草日趋严重。1984～1986年我们施用96%草达灭乳油,在早稻秧田和本田进行探索试验、推广应用,1984年作小区试验,1985年进行示范与推广,1986年进行大面积应用,施药面积达5万余亩。结果认为草达灭是稗草的克星,且能与杀虫剂混用兼治二化螟,此外,尚可减轻稻纹枯病的发生,深受广大农户的好评。一、防治效果稻田施用草达灭对稗草杀伤力很强,对牛毛草防效亦佳,对异型莎草防效较差,对其他阔叶杂草无效。
In recent years, due to the extensive management of farmland in Wenzhou City, weeds have become increasingly serious. From 1984 to 1986, we applied 96% Caida degreasing oil, explored and experimented on early rice seedling and Honda. The experiment was conducted in 1984 and plotted and popularized in 1985. Large-scale application was carried out in 1986 with an applied area of 5 More than 10,000 acres. The results showed that the herbaceous off is barnyard grass nemesis, and can be mixed with insecticides and Chilo suppressalisthus, in addition, still can reduce the occurrence of rice sheath blight, praised by the majority of farmers. First, the prevention and treatment of rice paddy grass to kill off on the strong lethal Echinochloa crusgalli control effect is also good, Shaped control of Shaoxing less effective on other broadleaf weeds is invalid.
