MANAGING WHITE MOLD OF LIMA BEANS WITH REDUCED RISK FUNGICIDES AND BIOFUNGICIDES

摘要

White mold (Sclerotinia sclerotiorum) of lima beans (Phaseolus lunatus) is an endemic disease in Delaware and Maryland. Acreage in coastal regions and along the Delaware Bay often experience yield losses of 20%. During the development of a pest management strategic plan in 2003, lima bean producers ranked white mold as the most important disease problem. At the same time, fungicide options for managing white mold were limited following the loss in availability of benomyl.
