Potato blight is a plant disease caused by the fungus-like organism Phytophthora infestans. It primarily affects potato and tomato plants, leading to dark, water-soaked spots on leaves and stems. If not controlled, the disease can spread rapidly, causing significant crop loss.
The blight thrives in cool, moist conditions, making it a common problem in wet climates. Farmers often use fungicides and resistant plant varieties to manage the disease. Early detection and proper management are crucial to prevent the spread of potato blight and protect food supplies.
