Washington State University Professor and Extension Specialist of Entomology Doug Walsh will be detailing the integrated pest management (IPM) strategies currently recommended on hops. Acreage of hops has increased dramatically in response to increased demand associated with the revolution in American craft brewing. Regional craft brewers seek local sources of hops and hop plantings are being established in nontraditional hop growing areas and hop plantings are also being re-established in areas that production had moved away from in the past. Doug will be highlighting the 3rd Edition of the Field Guide for Integrated Pest Management in Hops that will be available for distribution in early December, 2015. This 3rd edition of the hop IPM handbook is expanding its scope and now addresses pests on a national level rather than being specific to the Pacific Northwest. Doug will also detail the results of several recent studies on hops. One study documents that even under high-hopping regimes common in the brewing of India pale ales that hops contribute little to the pesticide load in beer. Doug will also touch on the work he and his colleagues at Washington State University are conducting on identifying molecular markers for acaricide resistance in spider mite populations that infest hops in Washington State.
