活体生物在农药残留降解跟踪试验的研究与应用

摘要

One key factor restricting the improvement of vegetable quality is pesticide residue. The pesticide residues degradation in cabbage of cyhalothrin, imidacloprid and dimethoate with high usage frequency in vegetable pests control, high efficiency, low toxicity and low residues, has been traced for 17 days by living organisms. The results show that it is feasible to test the degradation of pesticide residues in agricultural products qualitatively by bioassay.%农药残留是影响蔬菜品质提高的重要因素之一，利用活体生物对蔬菜病虫害防治中使用频率较高的三氯氟氰菊酯、乐果、吡虫啉等三种高效、低毒、低残留的农药在甘蓝中的残留浓度降解作了为期17d的跟踪检测，结果表明，利用生物检测法对农产品农药残留浓度降解进行定性反应是可行的。
