Cauliflower (Brassica oleracea) and other cruciferous crops including cabbage, brussels sprouts and broccoli are susceptible to many diseases. Alternaria leaf spot and downy mildew are common in crucifer production and can reduce plant yield and market value. Alternaria leaf spot, in contrast to downy mildew, is favored by warm, moist weather.
