Fabian D. Menalled

Associate Professor; Ph.D. 1996, University of Massachusetts; B.S. 1985, University of Buenos Aires, Argentina. Cropland Weed Specialist. My research and extension programs are focused in developing and delivering information on the integrated management of agricultural weeds. I am interested in understanding the mechanisms conditioning the abundance and distribution of annual and perennial weeds in agricultural systems. My research includes weed population and community dynamics, crop-weed competition, herbicide resistance, and weed management in conventional and alternative cropping systems.
