View Print Version
WA 38 Test Block at the Sunrise Orchard

Join WSU for a fall field day discussing horticulture and tips to optimize fruit quality of WA38 Cosmic Crisp™, WSU’s newest breeding program release. With more than 637,224 WA38 trees in the ground already, WSU and the Washington Tree Fruit Research Commission are working hard to provide growers with the information they need to choose training systems, pruning systems, rootstocks, pollinizers, and management techniques for high-quality fruit.

WA 38 Tips to Optimize Fruit Quality is the second of the two* field day events. The focus of this field day event is management tips for consistently superior fruit quality. Dr. Stefano Musacchi, WSU Professor of Horticulture, will demonstrate a new top grafting trial and discuss how horticulture systems impact pack out. Ines Hanrahan, Washington Tree Fruit Research Commission researcher, will describe tips to achieve high pack outs, including how to determine optimal harvest dates, pluses and minuses of one versus two picks, and the utility of pre-harvest fungicide applications. Karen Lewis, WSU Tree Fruit Extension, will show ways to incorporate mechanization, such as hedging, in WA 38 management.
