Proper identification of damage, defects, diseases, and disorders is the first step in solving the issue and producing quality fruit. Many issues can be difficult to identify because they look similar but may have completely different causes. To help out, we are developing tools to help you identify the problems. The first set of tools is a series of topical posters: Honeycrisp Defects, Postharvest Disorders, Insect Damage, Preharvest Defects, and Apple Fruit Diseases. To find out how to get your posters visit our sale page.
The next tool is an online guide to defects, diseases, and disorders which will include 360° view rotators that show different manifestations of each of the major defects and disorders. The first module of this guide, Postharvest Diseases, is now online. Visit our ID Guide Table of Contents page to see the Postharvest Diseases galleries.
The third tool underdevelopment is a replacement of the “Quick Identification Guide to Apple Post-harvest Defects and Disorders” card set that came out in 2005 and is now out of print. The new guide will update the old information as well as expand the content to include more defects and more examples of different varieties. Once the print version of the guide is completed, we will develop an App version of the guide.
