摘要
20%寡聚酸碘水剂(AS)的有效成分为氨基寡糖素与碘的络合物,采用室内生物活性测定及田间药效试验,以50%乙烯菌核利可湿性粉剂(WP)1000倍液为对照药剂,评价了20%寡聚酸碘AS对黄瓜灰霉病的防治效果。室内抑菌试验结果表明:20%寡聚酸碘AS1000倍液、1500倍液、2000倍液的抑菌率分别为97.30%、45.90%、14.00%,均低于50%乙烯菌核利WP1000倍液(100.00%)。田间药效试验结果表明:20%寡聚酸碘AS1000倍液、1500倍液的田间防效分别为81.66%、74.80%,均高于50%乙烯菌核利WP1000倍液(73.87%)。
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%).
