Dr. Brent Sellers

Professor & Center Director, Weed Science and Invasive Plants
Extension Weed Specialist

Program Areas

Dr. Brent Sellers examines weed biology and ecology related to pasture and rangeland management strategies. His research explores weed control in fence rows and pasture borders, invasive weeds and management strategies, which includes cultural, herbicidal and biological control methodologies. Dr. Seller’s extension program focuses on educating cattle ranchers and ranchette owners on cost effective weed control strategies. He identifies cost effective weed control programs for forage grasses such as bahiagrass, limpograss, bermudagrass and other commonly grown forages.
