摘要
为了探明腐霉利在新疆北部地区黄瓜上残留特性和使用安全性,通过田间试验和室内检测,研究了腐霉利在黄瓜中的最终残留量。结果表明:以腐霉利50%可湿性粉剂562.5~750.0 g/hm2(有效成分),连续施药2~3次,最后一次施药后3 d收获的黄瓜中腐霉利残留量均低于0.13 mg/kg,推荐该药在黄瓜上的安全间隔期为3 d。
In order to study the residual characteristic and safety of procymidone in cucumber of the Northern Xinjiang,field experiment and laboratory testing were conducted to reveal the final residues of procymidone in cucumber.The results showed that when the cucumber was sprayed 2 to 3 times with 562.5~750.0 g/hm2(effective constituent)of procymidone,the last application was done 3 days before harvesting,the residue of procymidone in the harvested cucumber was lower than 0.13 mg/kg.It was suggested that the preharvest interval of procymidone in cucumber was 3 days.
