Cucurbit Weed Update
Chuck Bornt, Team Leader, Extension Vegetable Specialist
Eastern New York Commercial Horticulture
As many of you know, we don't have a whole lot of post-emergent herbicides at our disposal for cu-curbits, and those that we do have are more grass herbicides then broadleaf materials. However, halosulfuron (Sandea or Profine), which is also one of our main broadleaf pre-emergent, is labeled and can be quite effective if used properly. If you used either Sandea or Profine pre-emergent even with another pre-emergent, we again would expect to see a few weeds such as Common Lambquar-ters and Ragweed start to breakthrough our pre-emergent herbicide barrier.

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.
