“易卫杀”是高效、低毒、有发展前途的农药。其残留量分析方法,目前国内未见报道。为了制定农药安全使用标准,正确掌握农药使用剂量,防止农药污染环境,保护人畜健康,研究它的残留量分析方法很有必要。测定稻米中“杀虫双”和“巴丹”的残留量,贵州农学院已经研究出了薄层分析方法。该法灵敏度高,回收率好,变异系数比较小,且设备简单,容易操作,而“易卫杀”同?杀虫双”、“巴丹”一样,都是沙蚕毒素的衍生物。因此,可以直接采用这个方法进行试验。薄层分析法是通过测定沙蚕毒素来分析“杀虫双”和“巴丹”的残留量的,能否用于“易卫杀”残留量的测定,关键在于添加在米样中“易卫杀”的回收率和变异系数是否合乎要求。如果这个问题解决了,可说明贵州农学院创立的薄层测定分析方法也可以直接作为稻米中“易卫杀”农药残留量测定的分析方法。
“Yi Wei kill” is efficient, low toxicity, promising pesticides. The residual amount of analysis, no reports at home. In order to formulate standards for the safe use of pesticides, it is necessary to correctly understand the dosage of pesticides, prevent the pesticides from polluting the environment and protect the health of humans and livestocks. It is necessary to study its residual amount analysis method. Determination of rice “insecticidal double” and “Badan” residues, Guizhou Agricultural College has developed a thin layer analysis. The method has the advantages of high sensitivity, good recovery rate, small coefficient of variation, simple equipment and easy operation, and “easy to kill” as “insecticidal double” and “Badan” are derivatives of nereistoxin. , This method can be used directly to test thin layer analysis method is the determination of Nereis textiles to analyze the “insecticidal double” and “Badan” residues can be used for “easy to kill” the determination of the amount of residue, The key is to add in the sample in the “easy to kill” recovery and coefficient of variation is satisfactory .If this problem is solved, it can be shown that Guizhou Institute of Agriculture established thin layer assay method can also be used directly as rice “easy to kill ”Determination of pesticide residues analysis method.
