Powdery Mildew of Pea

Powdery mildew is a common fungal disease of peas caused mainly by Erysiphe pisi. It appears as white, powdery fungal growth on leaves, stems, and pods, leading to reduced photosynthesis, stunted growth, and lower yield. The disease is favored by warm, dry conditions with high humidity at night. Management includes planting resistant varieties, applying fungicides when necessary, and practicing good field sanitation to reduce overwintering spores.
