Preventing the Spread of Phytophthora ramorum via Water


Preventing the Spread of Phytophthora ramorum via Water:

Research and Coordination Workshop & Best Management Practices Meeting350_MG_3396

Location:   Allmendinger Conference Center Washington State University Research and Extension Center 2606 West Pioneer Puyallup, WA 98371 Dates: June 28-30, 2011 Organized by: Gary Chastagner, Washington State University and Susan Frankel, USDA-Forest Service, Pacific Southwest Research Station Sponsored by: Washington State University and the California Oak Mortality Task Force

Local Arrangements: Gary Chastagner, 253-445-4528, chastag@wsu.edu and Marianne Elliott, 253-445-4596, melliott@puyallup.wsu.edu

Preventing the spread of Phytophthora ramorum via water was the focus of a two and a half day workshop attended by over 50 regulators, researchers, and industry representatives from the Western and Southeastern U.S., and Washington DC.  The workshop’s mission was to coalesce research, management and regulations to develop effective, economical and environmentally acceptable ways of limiting P. ramorum spread via contaminated nursery run-off.  The group visited a Gig Harbor retail nursery site where P. ramorum had leaked out of the nursery and infected riparian salal plants to review treatments and mitigations. Formal talks covered the incidence and location of P. ramorum recovery from waterways, water baiting techniques, risks and impacts for WA, and treatments to reduce the risk of spreading inoculum in water.  Research and education/outreach needs identification, group exercises and discussion concentrated on nursery treatments and water management, monitoring, and notification of downstream users of contaminated water.

Questions to determine the likelihood of P. ramorum infection


Questions to determine the need to submit a homeowner sample in Washington State

1) The plant displays leaf blight, defoliation, or stem die back symptoms similar to those shown in the photographs.
a. Yes- go to 2
b. No- Sample can be discarded
2) What plant is affected?
a. The plant is a camellia, rhododendron, pieris, kalmia, viburnum, or lilac purchased since 2002- Submit sample
b. The plant is growing next to a camellia, rhododendron, pieris, kalmia, viburnum, or lilac purchased since 2002- go to 3
c. None of the above- unlikely P. ramorum. Sample can be discarded.
3) Is the plant a known host of Phytophthora ramorum?
b. Sample can be discarded

Confirm that nursery stock is purchased from a licensed, certified shipping nursery or that material is propagated on-site.

USDA APHIS
USDA APHIS
Inspect all incoming nursery stock (buy-ins, transfers, and returns) prior to introduction into the nursery facility. Avoid mixing incoming plants with existing stock until plants have been examined for disease symptoms by trained personnel. Plants to be inspected
For buy-ins of high risk plants, suspend the use of Phytophthora specific fungicides on 10% or 100 plants, whichever is smaller, for a 2 month period. This will show if fungicides used by the seller were suppressing symptoms prior to purchase.High risk plants for P. ramorum include rhododendron, camellia, pieris, kalmia, and viburnum. High Risk Phytophthora Plants
Arrange plants to minimize damage caused by P. ramorum should it enter the nursery.Avoid mixing high-risk genera (Rhododendron, Camellia, and Viburnum) with other host and non-host plants. It is recommended to keep a 2 meter break between high risk plants and other material. IMG_5475_2
Manage weeds on the nursery site as they could serve as alternate hosts for diseases or be potential reservoirs for disease organisms. weeds in gravel
