Technical Abstract: White mold is a serious disease of lentil worldwide, and it is caused by the fungus Sclerotinia sclerotiorum. Water soaking lessions and white mycelial growth may occur on leaves, stems and pods, and are characteristics of the disease. The pathogen may form black fruiting bodies called sclerotia on infected tissues. The pathogen can be soilborne and seedborne and is favored by cool and moist conditions and lush vegetative growth. Management practices of the disease include planting clean seeds, application of fungicides, and rotation with cereal crops.
