This Index page serves as quick links to the 360-rotator images for common defects, disorders, and diseases found in apples. The list is organized alphabetically under subcategories for each major section. Rotators contain one or more fruit in a way that allows the viewer to turn the image around to see multiple examples of the various conditions exhibited. There are also pop-up captions with explanatory descriptions.
Acknowledgment: The 360-rotators are the result of a collaborative project between WSU Tree Fruit Extension (WSU TFE), the Washington Tree Fruit Research Commission (WTFRC), and The Good Fruit Grower (GFG).
Lead personnel: Rob Blakey (formerly WSU TFE), Ines Hanrahan (WTFRC), and TJ Mullinex (GFG).
Technical assistance: Matthew Ziegler (WSU CAHNRS Communications) and Wendy Jones (WSU TFE).
