Major Diseases of Fruits with their Pathogen / Causal organism

A wide range of different pathogens affect tree fruit and nut crop production. These crops are affected throughout the various regions they are cultivated, including temperate, sub-tropical and/or tropical areas of the world. Collectively, the pathogens of these crops account for considerable loss in yield (both pre- and post-harvest), and fruit and nut quality; some of the pathogens are responsible for producing mycotoxins, further reducing quality. Many of the pathogens are endemic, yet others are exotic, and their management is further associated with unique issues.

The broad range of pathogens may affect foliage, wood, flowers, roots and developing fruit or nuts. In most cases they include readily identifiable pathogenic agents, including fungal pathogens, bacteria and viruses, but also, relatively amorphous, less definable conditions including replant diseases.
