Newly published in 2024, the latest WSU Extension guides help Washington tree fruit growers protect their crops and aid forage and biofuels producers in considering a crop of switchgrass.
Switchgrass is a warm-season perennial grass that has been produced for seed for more than 30 years in the Columbia Basin. Growers are often surprised to learn that you can grow switchgrass both as a long-term, sustainable forage and as feedstock for cellulosic biofuel. This free guide draws on more than two decades of research from WSU’s Irrigated Agriculture Research and Extension Center in Prosser, Wash., to teach best practices for establishing a vibrant switchgrass stand, discussing planting windows, weed management, fall dormancy, animal health issues, and more. Authors are WSU Forage and State Extension Agronomist Emeritus Steve Fransen, retired USDA-Agricultural Research Service soil scientist Hal Collins, and retired USDA-ARS weed scientist Rick Boydston.
The 2024 edition of this guide is now available, outlining use of pesticides registered on orchard insect, disease, and weed pests in Washington state. Includes efficacy and toxicity charts; cost is $25.
