Upcoming Events
Hudson Valley Orchard Weed Management Meeting

June 25, 2025 : Hudson Valley Orchard Weed Management Meeting
Poughkeepsie, NY
At this meeting, we will discuss previous research on using mulch for weed management, including the benefits of stacking mulch treatments with an organic herbicide program. We will then discuss the treatments in our field trial, discuss results to date, and get initial reactions from the grower, while viewing the field trial. We will then discuss the other study objective, using a mechanical weeding system to replace contact herbicide applications, currently underway in the Champlain Valley.
