APSnet Image of the Week

Stemphylium fruit spot of papaya caused by Stemphylium lycopersici. This disease is widespread in the tropics although unusual on fruit kept at room temperature and ripened within 5-7 days of harvest. Various hot and cold treatments, which papayas go through to meet quarantine requirements, and long-term storage and shipping are responsible for making the otherwise resistant papaya fruit susceptible.
