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:

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 ([email protected]).
