- Welcome, Introductions, and Purpose of Field Day (2:00 – 2:05 pm)
By Lisa DeVetter, Assistant Professor of Small Fruit Horticulture at Washington State University. - Review Changes in Soil Fumigation Landscape for Red Raspberries in Washington* (2:05 – 2:10 pm)
By Lisa DeVetter, Assistant Professor of Small Fruit Horticulture at Washington State University. - Decision-Making Tool for Nematode Management in Raspberry* (2:10 – 2:30 pm)
By Inga Zasada, USDA Plant Pathologist/Nematologist and Tom Walters, Ag Researcher at Walters Ag Research. Summary of parasitic nematode biology, impact of cover crops and soil texture on nematode management, and results from fumigant alternative and bed fumigation trials. - Which Soilborne Pathogens are Associated with Declining Red Raspberry fields?* (2:30 – 2:40 min)
By Jerry Weiland, USDA Research Plant Pathologist. Summary of key findings of soilborne pathogen survey about whether Verticillium, Phytophthora, and Pratylenchus (root lesion nematode) are associated with declining red raspberry sites. Information on the presence of raspberry bushy dwarf virus (RBDV) and Cylindrocarpon will also be discussed. - How do you Decide what Soilborne Disease Management Approach is Optimal for your Field Situation?* (2:40 – 3:20 pm)
Participatory Activity with growers; led by coordinators DeVetter, Zasada, Walters, and Weiland. Posters will be hung on the wall and individually titled: Telone, Pi-Chlor/Strike 60, Metam sodium, bed fumigation, tarping, and cover crops. For each poster and corresponding practice, growers will be asked to brainstorm strengths and weaknesses of each practice for soilborne disease management and overall easiness of adoption. - Questions and discussion between growers and researchers regarding soilborne disease management in raspberry* (3:20 – 3:30 pm)
Refreshments provided during question and discussion period. - Observe and discuss fumigation equipment on display* (3:30 – 3:55 pm)
Bed and broadcast fumigation rigs will be on display. The owners of each fumigation rig will discuss application. Coordinators DeVetter, Zasada, Weiland, and Walters will then facilitate a discussion on the strengths, weaknesses, and best practices for application.
- Evaluations and conclusion/wrap-up (3:55 – 4:00 pm)
