Wisconsin Extension Weed Management Workshop
Wisconsin Extension Weed Management Workshop
A full day of the latest weed management science, technology, and take-home-tips to improve weed control and profitability for ag service providers, farmers, agronomists, chemical applicators, and more.
From Basics to Breakthroughs:
Managing Weeds in a Resistant Era
Learn key fundamentals while also taking a deeper dive into resistance evolution to connect foundational concepts with practical, field-level implications and decision-making.
Join us for presentations and field plot tours, visit product and education booths throughout the day provided by workshop sponsors, participate in a weed identification contest, and enjoy morning and afternoon snacks along with a warm, catered lunch!
This event is hosted by the UW–Madison Division of Extension and the WiscWeeds Team.
