对不同剂量20％氰戊菊酯乳油在黄瓜上的农药残留量、降解率进行了检测，结果表明，黄瓜开花结瓜期喷药后3。13d20％氰戊菊酯乳油在黄瓜上的残留量从大到小依次为180g／hm^2、120g／hm^2、60g，hm^2；第7天之前各处理的降解率从高到低的排序为180gmm^2、120g／hm^2、60g／hm^2。处理60g／hm。从第3天起的残留量低于无公害黄瓜的最高限量标准，处理180gmm^2及处理120g／hm^2第7天前的农药残留量均高于无公害黄瓜的最高限量标准。

The amount of pesticide residues and the degradation rate on cucumber have been detected in different dose of 20% fenvalerate EC on cucumber. The results showed that the amount of pesticide residues and the degradation rate on cucumber of different dose of 20% Fenvalerate EC were in sequence of 180 g/hm^2, 120 g/hm^2, 60 g/hm^2, when 3-13 days after spraying of cucumber flowering fruiting period. The degradation rate of each treatment for high in the end sort of 180 g/hm2, 120 g/hm^2, 60 g/hm^2. The pesticide residues of on the third day before-treatment 60 g/hm^2 on cucumber were below the maximum limits for pollution standards cucumber, the pesticide residues of on the seventh day before-treatment 120 g/hm2 and 180 g/hm2 on cucumber were higher than the highest limits for pollution standards.
