Cullage Assessment & Education Program

Visit the new web site at:

The Cullage Assessment & Education website was developed in 2003 for the purpose of providing the public and tree fruit industry with information related to damage and disorders encountered during the cullage assessment phase of the postharvest process with emphasis on items related to export or quarantine. There were also useful materials for people involved with identification of fruit damage in the orchard. Since its inception, this web site has beome an important source for quarantine pest information, key export work plan information, and export training requirements and schedules. The most visited section of this site is the Identification Guide to Apple Postharvest Defects & Disorders. However, this section, as well as most of this site, is overdue for a major update. To that effect, this site will be discontinued by the end of 2017.

Don't Panic! All of the popular content currently found here will find new homes on one of two other sites: the WSU Postharvest Export web site; and the WSU Tree Fruit website. The majority of the export-specific content will be updated and relocated to the Postharvest Export web site. Information related to identification of diseases and disorders will be relocated to the WSU Tree Fruit website. A mjor update and upgrade are in order for the Defects and Disorders Guide: new images, more varieties, additional defects and disorders, and eventually, the addition of pear and cherries and other stone fruit. The older pages located on this web site will have the URL for the newer content at the top of the page when available. Please bookmark the new location so you don't loose access to the information.
