Abstract: The spores of Verticillium dahliae Kleb with medium pathogenity were artificially inoculated onto the seeds of cotton before they were coated with different types of seed coating agents. The results showed that the anti- fungal effect of the seed coating agent was the best which contained 20% carbofuran- thiram- carbendazin plus 0.1 Xiao Jun Ling- a newly developed fungicide, its relative control effect being as high as 65.6%,or a 5.3% increase as compared with that of vitavax 200FF(60.3% )－a standard Ameriean seed coating agent. Lint cotton yield per mu was 80.8 kg,being 34.7% and4.4% higher than the blank control and the vitavax 200FF treatment. -
