UGA vegetable plant pathologists shared information about Powdery mildew in cucurbits at the 2020 Southeast Regional Fruit and Vegetable Conference.
Cucurbit crops are highly susceptible to powdery mildew disease. The classic sign of the disease is the presence of white powdery spots on both upper and lower leaf surfaces that quickly expand into large blotches. When powdery mildew infects the majority of the foliage, the plant weakens, and the fruit ripens prematurely. To combat powdery mildew, two new fungicides have been released, Gatten and Vivando.
