Weed Day 2026

You can read about University of California weed science research but it’s hard to beat seeing it in person while networking with researchers from around the state.  That’s why pest control advisors, crop protection company cooperators, faculty, students and regulatory officials continue to gather at UC Davis for Weed Day to get a sense of the ongoing weed management research that is being conducted.

This year’s 67th Annual Weed Day will be held Tuesday, June 18, from 8:30 a.m. to 4:00 p.m. The morning session will begin with a field tour and demonstration of various weed control technologies. Then, after lunch, UC weed scientists will present information on projects that are either not in-season or located too far off-campus for viewing.
