25%顺式氯氰菊酯·茚虫威悬浮剂可用于防治大白菜、甜菜、甘蓝、花椰菜等十字花科蔬菜的小菜蛾。由于大量杀虫剂的频繁使用,导致小菜蛾对各类药剂产生了不同程度的抗药性,采用两种杀虫剂复配,可大大提高杀虫效果,又因悬浮剂的低毒高效,深受广大农民的欢迎。关于二者复配制剂的同条件分析方法,目前尚未见报道。本文建立了在同一液相色谱条件下同柱分离测定顺式氯氰菊酯和茚虫威的方法。实验结果表明该方法操作简便,分离效果好,准确度和精密度高。
25% cis-cypermethrin indoxacarb SC can be used to control diamondback moth, such as cabbage, beet, cabbage, cauliflower and other cruciferous vegetables. Due to the frequent use of a large number of insecticides, lead to various degrees of resistance of the Plutella xylostella insecticide, the use of two insecticides compound, can greatly enhance the insecticidal effect, but also because of the suspension of the low toxicity and high efficiency, deep Welcomed by the majority of farmers. About the two formulations with the same conditions analysis methods, has not been reported. This paper established a method for the simultaneous determination of cis-cypermethrin and indoxacarb in the same liquid chromatographic conditions. Experimental results show that the method is easy to operate, the separation effect is good, the accuracy and precision are high.
