摘　　要：为探讨ClO2用于防治棉花枯萎病的效果,通过和市场上常用的杀菌剂多菌灵、甲基托布津进行田间对比试验,结果表明:采用添加1%～2%棉花专用添加剂的80ppmClO2溶液,用灌根和喷雾相结合的办法,其平均死亡率可低达2.7%,而多菌灵、甲基托布津平均死亡率分别为19.3%和16.2%.可以看出,添加1%～2%的添加剂ClO2溶液防治效果明显优于多菌灵和甲基托布津.:The effect of controlling withered cotton by ClO2 with different concemtration was studied. Taking carbendaxol, thiophanate-methyl thiram as control at the same time .The results indicated that the effect of 80ppm ClO2 with 1%～2% specific additive of cotton by the method of combining spraying and soaking roots is excellent.The average rate of death for cotton can go down2.7%,and the average death rate of carbendaxol and thiophanate-methyl thiramare 19.3%,16.2% respectively.
