Dr. Sprague’s research and extension program focuses on integrated weed management, biology, ecology, and management of emerging problematic weeds, and understanding the interactions with weeds and other pests and pest/crop management practices. Her program emphasizes weed management in soybeans, sugar beets, dry beans, and potatoes.
