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.

Establishing an Enhanced Monitoring Program for Phytophthora Pathogens in Western Washington Streams At this meeting we will determine the level of interest and plan a program of stream monitoring for Phytophthora ramorum and other Phytophthoras in Western Washington. This may also serve as a template for monitoring other plant pathogens that can be moved in water.

Confirm that nursery stock is purchased from a licensed, certified shipping nursery or that material is propagated on-site. | |
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. | |
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. | |
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. | |
Manage weeds on the nursery site as they could serve as alternate hosts for diseases or be potential reservoirs for disease organisms. | |
