Research focuses on determination and quantification of the mechanisms and factors controlling the degradation, movement, and activity of pesticides and their metabolites in soil; and to use this knowledge to reduce pesticide use by increasing herbicide efficacy in agricultural production systems, and to decrease the risk of ground water contamination.
