弥粉法施药防治设施黄瓜主要病害技术的研究

以日光温室黄瓜为试材,分析了黄瓜主要病害的发生情况,研究了弥粉法施药技术模式对黄瓜主要病害的防治效果,以期获得设施黄瓜减药的技术模式。结果表明:在2017年春茬试验中,弥粉法施药技术模式对黄瓜霜霉病、白粉病的防效分别为85.74%、86.70%;2017年秋茬试验中,弥粉法施药技术模式对黄瓜霜霉病、白粉病、灰霉病的防效分别为84.18%、85.57%、80.91%,显著优于常规喷雾处理,且农药使用量减少了85.20%。说明弥粉法施药技术模式适合在日光温室黄瓜主要病害防治中使用。

Study on Main Diseases Control Technology of Cucumber in Facilitiesby Powder Application

The solar greenhouse cucumber was taken as the experimental material, the occurrence of themain disease was analyzed,the control effect of the powder application method on the main diseases of cucumber was studied, in order to get the technical model of drug reduction of cucumber in facilities. The results showed that in the spring test of 2017, the powder application method was applied to cucumber downy mildew and powdery mildew. The control effects were 85. 74% and 86.70% respectively. In the autumn test in 2017,the control effects of the powder application method on cucumber downy mildew, powdery mildew and gray mold were 84. 18%, 85.57% and 80.91%, respectively and significantly better than conventional spray treatment, and pesticide use reduced by 85. 20%. It was indicated that the powder application method was suitable for use in the prevention and control of main diseases of cucumber in solar greenhouse.
