Abstract The effective component of 20% iodine oligosaccharide acids agent（AS）is the complex of chitin oligosaccharide and iodine．The antifungal effect of 20% iodine oligosaccharide acids AS against cucumber gray mold（Botrytis cinerea）was tested by allied toxicity measurement and field efficacy trials．The results showed that the bacteriostat ratios of 20% iodine oligosaccharide acids AS diluted 1 000 times，1 500 times，2 000 times were 97.30%，45.90%，14.00%，respectively，which were all lower than that of the 50% vinclzolin WP diluted 1 000 times（100.00%）．The field control effects of 20% iodine oligosaccharide acids AS diluted 1 000 times，1 500 times were 81.66%、74.80%，respectively，which were all higher than that of the 50% vinclzolin WP diluted 1 000 times（73.87%）．
