Thwarting Phytophthora ramorum: An Interactive Poster on Breaking the Disease Cycle.

Betsy Randall-Schadel and Scott Redlin, Plant Epidemiology and Risk Analysis Laboratory, USDA-APHIS-PPQ-CPHST, Raleigh, NC 27606; (919) 855-7544; betsy.randall-schadel@aphis.usda.gov

A proposed disease cycle, discussed in Presentation No. 50, “Thwarting Phytophthora ramorum: Breaking the Disease Cycle”, will be presented in an interactive format. The lack of a single mitigation measure to effectively eliminate P. ramorum from nursery stock suggested the value of a diagram highlighting points in the disease cycle where multiple mitigations may be applied. For each point, potential mitigation measures are listed. The diagram was compiled from scientific sources including published papers and proceedings of science panels. The proposed P. ramorum disease cycle is being presented as an interactive poster to prompt and capture discussion.
