摘要
采用田间试验方法测定生防菌H1、H2对黄瓜霜霉病的防效。结果表明:生防菌H1、H2对黄瓜霜霉病的防效分别为35.28%、35.75%,说明生防菌H1、H2不只对黄瓜白粉病效果明显,对黄瓜霜霉病也表现出抑制作用,具有一定的杀菌广谱性。
The control efficacy of H1 and H2 against cucumber downy mildew were studied,the disease index was collected and analyzed based on the plant disease control experiment in field.The results showed both of them had the bio-control efficacy,with 35.28% and 35.75% against cucumber downy mildew,respectively.H1 and H2 strains had not only the significant control efficacy against cucumber powdery mildew,but also the inhibiting ability to cucumber downy mildew.They both had boad-spctrum sterilizing characters.
