Research Interests
Dr. Kells'
research and extension program focuses on integrated weed management, biology
and ecology of perennial weeds, and weed interference. His program emphasizes weed management in
corn, forage crops, and small grains.
Classes Taught
CSS 402-Principles of Weed Science
Weed biology and ecology. Cultural, mechanical, biological, and chemical control
practices. Herbicide action, selectivity in plants, and effects on environment.
