Vegetable Crop Update #9
Updates provided by Amanda J. Gevens, Chair, Associate Professor & Extension Specialist, UW-Madison, Dept. of Plant Pathology
In this issue we address the following topics:
potato production updates
Russet Burbank injury
Disease forecasting for early and late blight of potato
Hop downy and powdery mildew
Be on the look out for downy mildews in other crops. Environmental conditions which favor downy mildew in one crop typically favor it in others, even though the pathogens are unique to specific crop groupings. For example, last year we reported hop and basil downy mildew in the same week (around this time in June).
