Members of the National Plant Diagnostic Network (NPDN) responded to the introduction of Phakopsora pachyrhizi, the fungal pathogen that causes the disease known as Asian soybean rust, by elevating key laboratory readiness by offering morphological and molecular identification training workshops, by continually updating the NPDN standard operating procedures, and by providing instruction for how and what information to transmit to the National Repository. The NPDN Diagnostic Subcommittee has coordinated these efforts. Prior to and since the arrival of P. pachyrhizi in the United States in November 2004, the NPDN coordinated workshops with Reid Frederick at the Agriculture Research Service, Fort Detrick, and Laurene Levy of the USDA, PPQ, CPHST laboratory. Additionally, Mary Palm, the APHIS national mycologist, participated in workshops and conducted conference call training sessions using mounted, sealed slides of spores mailed prior to the calls. In cooperation with USDA-ARS personnel, a number of the regional laboratories participated in a real-time PCR study designed to detect the presence of soybean rust in the early stages of infection. The Diagnostics Subcommittee has helped coordinate NPDN members working with the Pest Information Platform for Extension and Education (PIPE), the system that tracks soybean rust incidence through sentinel plot surveys. Updates of confirmed identifications were posted on the NPDN website and new finds were described in the NPDN National Newsletter. The NPDN laboratories have continued to provide a coordinated effort for the confirmation of soybean rust as it spreads.
