摘要
Field experiments were carried out in Changsha and Zhengzhou to determine residue and degradation dynamics of lufenuron in cotton leaves,cotton seeds and soil.Results show that its recovery rate was in the range of 86.0%-94.7%,88.5%-92.1% and 83.9%-97.7%,and its minimum detectable concentration was 0.025,0.025 and 0.006 mg·kg-1,respectively.And its half-life was 3.06-3.45 days in cotton leaves and 2.51-2.88 days in soil.In the cotton seeds harvested from fields applied with a recommended dose and a high experimental dose,respectively,its final residue was undetectable.The recommended MRL for lufenuron in cotton seed is 0.05 mg·kg-1 in China.
