Occurrence of downy mildew in cucurbit crops varies every year depending on the pathotypes of the pathogen that are present and as well as when the pathogen is dispersed to a region. Typically the disease is most important on cucumber because this cucurbit type is susceptible to all know pathotypes. See the Cucurbit Downy Mildew Forecast website for current occurrences and forecasts.
