Sep 18, 2017WA 38 (Cosmic Crisp) tips to optimize fruit quality
Washington State University’s Sunrise Orchard in Rock Island, Washington, will be the setting from 3 p.m.-5 p.m. for a fall for a fall field day discussing horticulture and tips to optimize fruit quality of WA 38 (Cosmic Crisp), WSU’s newest breeding program release.
With more than 637,224 WA 38 trees in the ground already, WSU and the Washington Tree Fruit Research Commission are working to provide growers with the information they need to choose training systems, pruning systems, rootstocks, pollinizers and management techniques for high quality fruit.
The focus of this field visit is management tips for consistently superior fruit quality. 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, 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 Extension, will show ways to incorporate mechanization, such as hedging, in WA 38 management.
