Summary:
Scaling of IPM systems is important for pests capable of long-distance dispersal and where management must be preventative rather than remedial. The life history characteristics of powdery mildew diseases make spread of powdery mildews probable through a network of susceptible fields at the landscape level.
This project seeks to develop preliminary data on landscape-level outbreaks of hop powdery mildew and fit a network model as a proof-of-principle that knowledge of initial inoculum density, spatial distribution of diseased yards, and other easily measured risk factors influence epidemic development. With this scaffolding, disease control measures that may eliminate primary inoculum may be more strategically deployed to disrupt the pathogen lifecycle. If coordinated across farms, this approach could be scaled up to an area-wide disease management system. Objectives 1.Collect preliminary data to characterize landscape level outbreaks of hop powdery mildew in selected production regions in Oregon. 2. Develop and deliver a stakeholder-driven outreach program that explains, integrates, and demonstrates powdery mildew management concepts appropriate for multiple scales (field, farm, and regionally) to producers and their key advisers. This project addresses priorities identified by the Western IPM Center, National Roadmap for IPM, a Pest Management Strategic Plan, and other verifiable evidence of relevance to stakeholder priorities. We anticipate the insights from this work could provide a framework for similar approaches with other powdery mildews where pathogen survival and dispersal are drivers of regional disease outbreaks. The work will also provide a foundation for successfully leveraging other resources. Objectives: 1.
