ROCKVILLE, MD, UNITED STATES, November 7, 2025 /EINPresswire.com/ -- Harvest weed seed control (HWSC) is an Australian-born weed management system that is gaining traction in the U.S., as more farmers try out tactics like seed impact mills and chaff lining to manage weeds that escape control during the growing season. But there’s still a lot to learn about how these tools work in North America, and the new Harvest Weed Seed Control webpage series from the GROW (Getting Rid of Weeds) Network is here to help you navigate it!

The new webpage series starts with a main page that serves as a one-stop shop for everything HWSC. It covers a range of topics, including:
--What harvest weed seed control means
--Current HWSC methods
--Cropping systems and weeds that are best suited for HWSC
--How long it takes HWSC to make a noticeable difference
--How to set up a combine for HWSC
