Cucurbit downy mildew (CDM), is an economically significant disease of cucurbitaceous crops in the Eastern United States (US). Cucumbers are particularly susceptible and as a result, disease management of P. cubensis relies heavily on fungicide use. To determine the efficacy of fungicide applications on CDM in pickling cucumber regarding disease severity and marketable yield, field experiments were conducted from 2013 to 2016 in North Carolina. Several fungicide programs were effective in the suppression of disease, and spray programs that included tank mixes with protectants and alternations of fungicide modes of action, resulted in lower levels of downy mildew and increased marketable yield.
