Integrated Weed Management (IWM) incorporates multiple management techniques such as physical, chemical, biological, and cultural methods to control weeds.

A Practical Guide for Integrated Weed Management in Mid-Atlantic Grain Crops has more in-depth information about different IWM tactics and how to coordinate these tactics to create an integrated weed management plan. Find more information at

Cover Crops for Weed Management

Cover crops are well-known for their soil health benefits however, their ability to suppress weeds is not fully known. High-residue cover crops have the potential to suppress winter and summer annuals. Our research has focused on the use of cover crops to suppress horseweed as well as investigate the potential of herbicide carryover from the cash crop to the cover crop.  Research results can be seen under the cover crops tab on the right.

Harvest Weed Seed Control

Harvest weed seed control (HWSC) is a newer weed management practice that focuses on destroying seeds that will become weeds in future seasons. Research efforts are aimed at determining which weed species are controlled by these practices, by comparing seed shattering to crop harvest, and determining the overall efficacy of this practice on two major weeds in Virginia: Palmer amaranth and common ragweed. Results from this research can be seen underneath the Harvest Weed Seed Control tab to the right.
