采用10种常用的杀菌剂和正常沼气发酵的青蒿沼液对云南红豆杉叶斑病病原菌进行抑制对比实验.实验结果表明,70%甲基硫菌灵500倍液、青蒿沼液、75%百菌清500倍液、40%菌核净600倍液、50%福美双500倍液、杀毒矾500倍液、69%烯酰-锰锌500倍液、72%霜脲-锰锌500倍液、58%甲霜灵-锰锌200倍液、60%多菌灵1500倍液、15%多抗霉素600倍液的平均抑制效果依次为77.27%、75.80%、75.67%、71.12%、69.52%、69.47%、69.00%、67.62%、59.5%、19.82%和17.17%,差异达到极显著水平,其中青蒿沼液有着良好的抑制效果,其平均抑菌率仅次于70%甲基硫菌灵.
10 kinds of commonly used fungicides and normal biogas fermentation of Artemisia annua L. juice were used to inhibit the pathogen of yew leaf spot disease in Yunnan.The results showed that 70% thiophanate-methyl 500 times liquid, Artemisia annua liquid, 75 % Chlorothalonil 500 times, 40% sclerotinum 600 times, 50% thiram 500 times, anti-virus alum 500 times, 69% enoyl-manganese zinc 500 times, 72% The results showed that the average inhibitory effect of Bacillus subtilis 58%, metalaxyl-manganese-zinc 200 times, 60% carbendazim 1500 times and 15% polyoxin 600 times were 77.27%, 75.80%, 75.67%, 71.12% , 69.52%, 69.47%, 69.00%, 67.62%, 59.5%, 19.82% and 17.17%, respectively. The difference was significant. Among them, Artemisia annua L. had good inhibitory effect, and the average inhibitory rate was only 70% Thiomersie.
