Technical Abstract: Stemphylium blight is a serious disease of lentil, and it is caused by the fungus Stemphylium botryosum. Tan to light brown lessions are early signs of the disease on leaves and pods, particularly in the last third of the growing season, and are characteristics of the disease. The pathogen may form black masses of conidia on infected tissues. The pathogen can be soilborne and seedborne and is favored by warm and moist conditions. Management practices of the disease include planting resistant cultivars, clean seeds, and application of fungicides.
