Potato diseases can significantly impact crop yield and quality. Common diseases include late blight, caused by the fungus-like organism Phytophthora infestans, which leads to dark spots on leaves and tubers. Another prevalent issue is potato scab, a bacterial infection that results in rough, scabby patches on the potato skin. Preventive measures are essential for managing these diseases. Crop rotation, proper irrigation, and the use of disease-resistant potato varieties can help reduce the risk. Additionally, regular monitoring and timely application of fungicides or bactericides can protect potato crops from severe damage.
