Auburn University Extension cautions cucurbit producers to be wary of Cucurbit downy mildew. The build up of downy mildew in Florida is an indicator that the disease will show up in Alabama later in the season. Cucurbit crops are susceptible to the disease.

It is important for growers to be proactive and not reactive when managing this disease. Growers can reference the Southeast Vegetable Crop Handbook for information on controlling downy mildew with fungicides.
