| 摘 要： | 茚虫威是一种广谱高效的氨基甲酸酯类杀虫剂,低毒低残留。采用气相色谱法对茚虫威在土壤中的残留进行分析,采用田间试验方法研究了茚虫威在土壤中的消解动态。结果表明,茚虫威在土壤中消解较快,其残留消解动态曲线符合化学反应一级动力学方程,在土壤中的半衰期为7.6天。说明茚虫威使用后在环境(土壤)中可以较快地消解,从而可以较好地保障生产安全。

| Abstract: | Indoxacarb is a broad-spectrum,effective,low-toxic,less-persistent and Carbamic pesticide.In this paper,we analyzed the residue and degradation dynamics of Indoxacarb in the soil using gas chromatography and field test method.We found that Indoxacarb was quickly degraded in the soil and the degradation curve was conformed to the first-order dynamic equation.The half-life of Indoxacarb is 7.6 days in the soil.The results indicated that Indoxacarb could be quickly degraded in the environment and was safe for ... |
