Technical Abstract: Botrytis gray mold is a serious disease of pea worldwide, and it is caused by the fungal pathogen Botrytis cinerea. Grayish, irregular moldy lesions on leaves, stems and pods are characteristics of the disease. The pathogen may form black surviving bodies called sclerotia on diseased lessions. The pathogen can be soilborne, seedborne and is wind-dispersed. Practices to manage the disease include planting resistant cultivars and application of fungicides.
