Interagency Noxious Weed Symposium 2026

It takes place at LaSells Stewart Center in Corvallis.

The organizer describes the audience as natural resources professionals working on invasive plant management in the Northwest.

It suits land managers, agency staff and weed control practitioners in the Northwest, since the sessions cover herbicide updates, biocontrol, aquatics and rangeland invasive grasses, and the state agriculture department's regional staff are on the program. Pesticide recertification credits for Oregon and Washington add practical value for licensed applicators, while people working outside the region or outside invasive plant management would find the material narrow.

Attendees at natural resources and vegetation management meetings usually wear casual or business casual clothing, such as field-style pants, a collared shirt or fleece, with layers for a Corvallis December.
