WA 38/Cosmic Crisp® Events & Defect Guide

Posted by wendyej | September 11, 2020

New Publication

The new guide, WA 38 Common Defects and Unique Characteristics Near Harvest and During Storage is now available. The guide includes defects visible during the growing season, at harvest, or after storage. There is also a section on defect characteristics unique to WA 38. Each defect section includes when it would first be detected, incidence rate, description, possible defects with similar characteristics, known management strategies and a photo gallery.

The guide was developed with a focus on defects typically observed in WA 38 to date. It does not include some commonly occurring defects of all apples such as bruising or decay. Defects only observed under special laboratory conditions known to exacerbate symptoms have been omitted.

The guide can be found here or on under the WA 38 tab. The guide was written by Ines Hanrahan, WA Tree Fruit Research Commission, and Carolina A. Torres, WSU Endowed Chair in Tree Fruit Postharvest Systems.
