为了全面准确地评价其生态环境安全性，指导腐霉利的科学合理使用，借助气相色谱检测技术，研究了腐霉利在番茄和土壤中的残留消解动态和最终残留。结果表明，在施用42d后，腐霉利番茄和土壤中的消解率均在90％以上，腐霉利在番茄与土壤中的半衰期分别为10．65d和14．2d，在试验条件下，腐霉利在最后一次施药后3、5、7d后的残留量均小于2mg／kg。根据测定结果，表明在试验条件下施用50％腐霉利可湿性粉剂防治番茄生长过程中所发生的病害是安全的。

Residual dynamics and final residues of procymidone in tomato and soil were studied.The result showed that at 42 days after spraying procymidone,the degradation rate in tomato and soil was over 90%.The half-live of procymidone is 10.65 days in tomato and 14.2 days in soil respectively.The final residues quantity is smaller than 2 mg/kg when the last spraying procymidone after 3、 5、 7 days.It is concluded that procymidone 50% WP would be safe in...
