The Goal of the Hop Program is a balanced combination of basic and applied research directed towards the development of integrated management strategies for hop pests. This dual focus is necessary to serve the long-term and short-term needs of hop growers. The focus on basic research will contribute towards our understanding of the biology and ecology of these pests, their natural enemies, and their host-plants, leading to enhancement of existing, and development of new, pest management strategies. The more applied research will contribute to the near-term pest management needs of hop growers in Idaho and other hop producing regions of the Pacific Northwest. Research projects currently in progress focus on the major arthropod and disease pests of hop in Idaho, the twospotted spider mite, Tetranychus urticae, the California prionus, Prionus californicus, and hop powdery mildew, Sphaerotheca humuli. A brief description of some current research projects is provided below.
