Cercospora leaf spot (Frogeye) (Cercospora capsici)
Spots on leaves are brown and circular with small to large light grey centres and dark brown margins. Spots on stems, petioles and peduncles are typically elliptical and also have light grey centres with dark borders. Infected leaves are shed. Extensive defoliation occurs under severe disease pressure. Fruits are not attacked. The fungus survives on seeds and in crop debris. The disease is favoured by prolonged periods of wetness.
- Plant resistant cultivars, if available.
- Use certified disease-free seeds.
- Practise good field sanitation.
