Research Interests

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.
