防治水稻干尖线虫病,国内外多采用变温浸种。近年来,我国又推广盐酸浸种。这些方法,都有一定的作用,但也存在不少缺点。1981年我们试用呋喃丹,在秧田作土壤处理,1982—1985年,又作了大面积的示范、推广,获得良好的防治效果。一、药剂防治试验结果从筛选出来的几种杀线虫剂比较来看,施药的比对照的发病率均显著降低。而3％呋喃丹颗粒剂的防治效果,均优于供试的 Prevention and treatment of rice tip nematode disease, at home and abroad to use more variable temperature soaking. In recent years, China has promoted hydrochloric acid soaking. These methods all play a certain role, but there are also many shortcomings. In 1981, we tried carbofuran to make soil treatment in the seedling field. From 1982 to 1985, we made a large-scale demonstration and popularized to get good control effect. First, the results of the chemical control test Several nematocides from the screening out of comparison, the application rate of the disease were significantly lower than the control. The control effect of 3% carbofuran granules was better than that of the test
