Interpretive Summary:

Technical Abstract: Powdery mildew is a serious disease of pea worldwide, and it could be caused by two fungal species Erysiphe pisi and E. trifolii. White powdery patches on leaves, stems and pods are characteristics of the disease. The pathogen may form black fruiting bodies called chasmothecia near the end of the growing season. The pathogen can be soilborne, seedborne and wind-dispersed. Management practice of the disease include planting resistant cultivars and application of fungicides.
