Comments
Anthracnose is found in all major vegetable growing areas worldwide and can cause large losses if left untreated
Management
Always plant disease-free seeds and transplants; seeds can be freed from infection by treating with hot water at 52°C (125.6°F) for 30 minutes; if disease is known to present, the field should be rotated with non-susceptible crops for a period of 3 years; plowing crop residue deeply into the soil r removing crop debris can help to reduce inoculum in the soil
