甜瓜几种主要病害的杀菌剂防治效果比较研究

Study on Control Effect and Compare of Treatment to Main Diseases with Fungicides in Muskmelon

试验针对甜瓜叶枯病、蔓枯病、疫病、白粉病,除草剂或化学品药害等,采用不同的杀菌剂进行防治效果比较研究。结果表明:15%三唑酮喷雾对甜瓜叶枯病,70%甲基托布津+68%金雷多米尔喷雾对甜瓜苗期蔓枯病,70%甲基托布津+68%金雷多米尔+12%松脂酸铜涂茎对甜瓜成株蔓枯病,50%苯菌灵+72.2%普力克+黄腐酸硒涂茎加敷土对甜瓜疫病,5%己唑醇喷雾对甜瓜白粉病,解害灵喷雾对误用除草剂或化学品药害等控制效果明显。

Aim at leaf blight,gummy stem blight,epidemic dicease,powdery mildew,herbicides or chemical injury of muskmelon,the control effect of deferent fungicides treatment on muskmelon diseases were compared.The results showed that 15% Ketotriazole spray to muskmelon alternaria spot,70%Thiophanate methyl and 68%Ridomil MZ gold spray to muskmelon seedling gummy stem blight,70%Thiophanate methyl and 68%Ridomil MZ gold adding 12%Resin acid copper salt daubing stem to muskmelon gummy stem blight,50% Benomyl and 72.2%Previcur adding fulvic acid selenium daubing stem to muskmelon phytophthora blight,5%Hexaconazole spray to muskmelon powdery mildew,75%Gibberellic acid（Jie-hai-ling）spray to herbicide or chemical hazard have evident control impact.The result will give a theory basis for control diseases in muskmelon production.
