己唑醇在猕猴桃果实腐烂病防治中的应用及残留分析

摘要

Experiments were conducted on spraying 1000-fold of 5% hexaconazole ME one time a week from May to June of 2014 to control Kiwifruit fruit rot and paper bagging 30 fruit after each spraying in Jiangshan, Zhejiang province. The results showed that the first two sprays had 76.98% control effect. Determination of residue in the mature bagged fruit showed non-detection in the flesh, and low content in skin.%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1000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。
