摘要
用乙嘧酚磺酸酯25%微乳剂防治黄瓜白粉病在2011年进行了两次试验。试验表明:乙嘧酚磺酸酯25%微乳剂对黄瓜白粉病有很好的防治效果,有效成分用量为150、225、300g/hm2时,对黄瓜白粉病的防治效果分别为80.3%～81.4%、87.6%～88.7%、88.5%～90.2%,对黄瓜植株安全无药害。
Effect of 25% bupirimate micro-emulsion against cucumber powdery mildew was studied on field conditions twice in 2011. The results showed that effect of 25% bupirimate mi- cro- emulsion against cucumber powdery mildew was obvious. When the dosage of effective com- ponents were 150, 225, 300g/hm2, the control effects were 80.3%-81.4%, 87.6%-88.7%, 88.5%-90.2% and 25% bupirimate micro-emulsion was safe to cucumber.
