摘　　要：在天津和吉林两地进行40%丙溴磷乳油在马铃薯植株和土壤中的残留动态研究,结果表明:40%丙溴磷乳油在马铃薯植株中,经8.5～11.5 d可降解90%,半衰期2.6～3.5 d;在土壤中经12.7～13.1 d可降解90%,半衰期3.8～3.9 d;14 d后,马铃薯中残留量均未检出,符合FAO/WHO规定的最高残留限量标准。Residue dynamics of 40%profenofos EC in potato plant and soil was studied in Tianjin and Jilin. The results indicated that it took 8.5-11.5 d to degrade 90% in potato plant,and 12.7-13.1 d in soil. The half-lives of 40% profenofos EC in potato plant and soil were 2.6-3.5 d and 3.8-3.9 d respectively. 14 days later, profenofos residue in potato was not detected, which agree with MRL regulated by FAO/WHO.
