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.

 Research Interests

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
