White mold of snap beans has been a challenge to manage in processing production fields in Wisconsin. When unmanaged, white mold can cause significant yield reduction, particularly in moist, warm years. The soilborne fungus Sclerotinia sclerotiorum is responsible for white mold in snap beans, as well as disease in a broad range of dichotomous food plants including other legumes, cucurbits, crucifers, and solanaceous crops. We have routinely conducted foliar fungicide efficacy trials to determine optimum timing and selection of fungicides for white mold control on snap beans in Wisconsin. Results of 2015 fungicide research trials are detailed below.
