The size of lesions caused by Stemphylium lycopersici on papaya (Carica papaya) fruits was affected by type of wounding, fruit maturity, duration of postharvest hot-water treatment, and duration of cold storage. A hot-water immersion treatment resulted in larger lesions than a hot-water spray. Susceptibility to infection increased with increasing maturity.
