摘要
为探讨二氧化氯对黄瓜霜霉病的防治效果,在温室大棚内开展不同浓度二氧化氯对黄瓜霜霉病的防治效果试验。结果表明:不同浓度的二氧化氯处理对黄瓜霜霉病均有防治效果,第3次施药后7 d二氧化氯粉剂1000倍液处理病情指数和防治效果分别为8.05和75.25%,防治效果良好;各二氧化氯处理黄瓜叶片有药害斑点,后期能够恢复;各处理的黄瓜植株长势无明显差异;各二氧化氯处理黄瓜结瓜数、产量均与清水处理差异显著。二氧化氯对黄瓜霜霉病具有较好的防控效果,有应用前景。
In order to investigate the control effect of chlorine dioxide against cucumber downy mildew,the control effects of different concentrations of chlorine dioxide against cucumber downy mildew was tested in greenhouse.The results showed that different concentrations of chlorine dioxide treatment had the control effect on cucumber downy mildew,7 days after the third application,the disease index and control effect of chlorine dioxide DP 1000 times solution treatment were 8.05 and 75.25%,respectively,with good control effect.The leaves of cucumber treated with chlorine dioxide had drug damage spots,which could recover later.There was no significant difference in the growth of cucumber plants among the treatments.The number and yield of cucumber of chlorine dioxide treatment were significantly different from those of water treatment.The control effect of chlorine dioxide against cucumber downy mildew is good,which has application prospect.
