Plant Health Virtual Conference: Downy Mildews Aren’t Powdery Mildews

Margery will clue you in to the mystifying world of downy mildews. It used to be that only rose growers knew what they were, but now anyone who grows coleus or impatiens has run up against a downy mildew at some time. Although they sound a lot like powdery mildews, the downy mildews aren’t even fungi. This means that you have to be very careful when you are choosing materials to protect your plants, because many popular leaf spot fungicides won’t touch a downy mildew. Learn about the symptoms and the management for downy mildew on a number of your major (and some minor) crops. You will never get downy mildew confused with powdery mildew again after this presentation! Speaker: Margery Daughtrey, Senior Extension Associate, Cornell University
