己唑醇在猕猴桃果实腐烂病防治中的应用及残留分析

Effect of Hexaconazole on Kiwifruit Fruit Rot and Its Residual

摘要: 猕猴桃果实腐烂病的病原菌为拟茎点霉菌（Phomopsis sp.）。2014年5 - 6月，采用5%己唑醇微乳剂1 000倍液喷雾，每周喷雾1次，连喷3次，每次喷施后套袋30个猕猴桃果实，防治猕猴桃果实腐烂病并对成熟后的果实进行己唑醇残留分析。结果表明，在猕猴桃幼果期喷雾2次，猕猴桃果实腐烂病防治率达到76.98%。对成熟后的猕猴桃残留己唑醇进行测定，结果表明，果肉未检出残留，果皮的残留量较低，并随时间的延长而减少。
