Fabian D. Menalled

Professor; Ph.D. 1996, University of Massachusetts; B.S. 1985, University of Buenos Aires, Argentina. Cropland Weed Specialist. Research and extension focused on integrated management of agricultural weeds. Understanding the mechanisms conditioning the abundance and distribution of annual and perennial weeds in agricultural systems. Weed population and community dynamics, crop-weed competition, herbicide resistance, and weed management in conventional and alternative cropping systems.
