Vegetable Crop Update #8

June 4th, 2018 | Posted in: Crop Updates

Updates provided by Amanda J. Gevens, Associate Professor & Extension Vegetable Plant Pathologist, Interim Co-Director of Wisconsin Seed Potato Certification Program, UW-Madison, Dept. of Plant Pathology

In this issue, we address:

  • late blight ‘look-alike’ disease Phytophthora nicotianae in North Carolina potatoes/tomatoes
  • national late blight updates
  • WI DSV accumulations – no thresholds met yet for late blight preventive fungicide application trigger
  • national cucurbit downy mildew updates
  • potato crop status updates

Please note that Amanda will be adjusting emergence dates for potatoes for generation of PDays and DSVs in forthcoming newsletters. She is glad to hear feedback on most appropriate dates for early, mid and late potato plantings in each of the 4 WI reporting locations (gevens@wisc.edu).
