摘要
在长沙和杭州2地进行田间试验,采用气相色谱法定量分析烯酰吗啉40%可湿性粉剂在黄瓜及其土壤中的消解动态,测定烯酰吗啉在黄瓜的消解半衰期分别为7.74d(湖南长沙)、7.82d(浙江杭州);在黄瓜地土壤中的消解半衰期分别为9.69d(湖南长沙)、9.53d(浙江杭州)。
Field experiments of the degradation dynamics of dimethomorph 40%WP in cucumber and soil were carried out in Changsha and Hangzhou.The GC method was used for the determination of dimethomorph residue.Results showed that the half-lives of dimethomorph were 7.74 days（Changsha）and 7.82 days（Hangzhou）in cucumber,9.69 days（Changsha）and 9.53 days（Hangzhou）in cucumber soil respectively.
