| Cercospora leaf spot
Frogeye leaf spot is a disease of peppers caused by the fungal pathogen Cercospora capsici. The fungus thrives in warm, humid conditions. It is often caused by diseased seeds or planting materials and promoted by poor air flow, low sunlight, overcrowding, improper soil nutrient and irrigation management and poor soil drainage.
Infected leaf has frogeye-shaped spots, about 0.2-1.5cm in size. The center of the spots is grayish-brown colored dead tissues. Masses of small black dot-liked fungal spores are found scattered on the dead tissues. During severe infection, yellowing and defoliation occur
Remove and destroy infected plants.
Practice crop rotation. Use diseased-free seeds or use resistant cultivars. Observe proper planting distances and maintain sanitation by removing a disposing of infected plant materials. Avoid working when plants are wet.
