Determination of Some Herbicides in Agricultural Products using Liquid Chromatography Tandem Mass Spectrometer (LC/MS/MS)

Abstract

Acidic herbicides are one of pesticide group used to protect plant and increase crop productivity by killing weeds. In the present study, the acidic herbicides are 2,4- dichloro-phenoxyacetic acid (2,4-D), bentazone, bromoxynil, fluazifop, fluroxypyr, imazethapyr, ioxynil and triclopyr. In Egypt, acidic herbicides are commercially distributed in different formulas and the national product of many tons of strawberries and frozen vegetables including green beans harvest were exported to different countries, making them two of the top ten commodities exported agricultural products in Egypt. Unfortunately, the residues of acidic herbicides determined easily using the quick, easy, cheap, effective, rugged and safe (QuEChERS) method. Therefore, a rapid and accurate method for the analysis of acidic herbicides residues in strawberry and green beans is
