Cover Story: Metribuzin is a pre- and post-emergence triazinone herbicide used to control annual grass and broad-leaved weeds in a variety of crops. The evaluation of this chemical on environmental and human health concluded that this pesticide has toxicity even at low doses. In environmental conditions, metribuzin degrades into three main metabolites: diketo-metribuzin, desamino-metribuzin, and desamino-diketo-metribuzin. These have high water solubility and soil mobility, so crop uptake is expected. Different methods have been reported for the determination of metribuzin but are scarce for its metabolites, particularly via gas chromatography. This study develops a fast and sensitive method for the analysis of metribuzin and three metabolites in soil and plants by UAE and GC-MS/MS that will allow monitoring their presence in food and the environment.
