Abstract
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.关键词
