INTEGRATED MANAGEMENT OF POSTHARVEST DISEASES OF POME FRUIT

Postharvest diseases that manifest during cold storage and shelf-life cause significant economic losses in pome fruit. The fungi that cause postharvest diseases are not sufficiently inhibited by low storage temperatures and reduced oxygen levels.

An integrated approach to postharvest disease management tries to reduce fruit susceptibility to infection, reduce pathogen inoculum potential, and apply control materials effectively. Orchard sanitation, removing decaying organic matter from the orchard floor and from within trees is critical to reducing pathogen inoculum. Reduction of fruit nitrogen content through minimal and timely fertilizer application, increasing fruit calcium content through foliar sprays, applying fruit resistance stimulants, harvesting without injuring the fruit and harvesting early in the maturity range all can enhance fruit resistance to infection.

The efficacy of fungicide or biocontrol treatments diminishes rapidly as the time between fruit inoculation and protective treatment increases. Fungicide application in the orchard before harvest or promptly after harvest can significantly reduce incidence of postharvest diseases.
