About

My research efforts focus on the soil behavior of herbicides. Specifically the herbicidal fate and residual activity in laboratory, greenhouse, and field trials, with analysis, evaluation, and assessment of herbicides used in row crop, forages, turf, vegetables, and perennial fruit and nut agriculture, and how these compounds can affect rotations to alternative and vegetable crops, and long term weed control.
