Vegetable Crop Updates Newsletter – September 20, 2026

UW Extension Logo

A Newsletter for Commercial Potato and Vegetable Growers Prepared by the University of Wisconsin Madison Vegetable Research and Extension Specialists

Hello,

Click here to find the UW Madison Division of Extension Vegetable Crop Updates Newsletter for September 20, 2026. In this issue I address the final weekly update on disease management models (Blitecast for late blight and P-Days for early blight), late season ongoing late blight management considerations, and cucurbit downy mildew. As we progress into fall, the newsletters will come with less frequency. We appreciate your continued interest in our research and extension work, and your engagement in vegetable production here in Wisconsin and beyond.

Wishing all a safe and successful harvest.

Regards,
Amanda
