My current appointment is 70% Extension and 30% Research in weed management in agronomic crops. My program focuses on providing research based weed management options for corn, cotton, peanut, soybean, small grains, and forage growers in South Carolina.
Alternative Cultural and Chemical Options for Herbicide-Resistant Palmer Amaranth and Annual Ryegrass
Evaluation of Winter Cover Crops for Weed Suppression
Evaluation of New Herbicide Chemistries in Corn, Cotton, Soybean, Peanut, Forages, and Small Grains
Extension and Outreach
Provide research based weed management information to growers at the county, regional, and state level
Train and update agronomic agents on relevant weed management systems
Editor of the annual South Carolina Pest Management Handbook
