Spread of Soybean Rust

• Windborne urediniospores
• Not seedborne planting contaminated seed will
  not result in SBR
• Soybean meal, grain, seed? NOT likely (see
  evidence of low risk)

2005 Timeline

• Jan- outreach, planning
• Feb- delist meeting on 4th for Coordinated
  Framework estimate budget
• Mar- survey natural hosts in south
• Apr- soybeans planted
• May-Nov- coordinated framework operating
• Nov- lessens learned (APS Nov 15-16, Nashville),
  plan for transition from APHIS

35
SBR Transition from APHIS

• September, 2005- Cooperative Partnership
  Agreement signed between RMA, CSREES, and the
  Southern Region Integrated Pest Management Center
  (SRIPMC) at North Carolina State University
  (funds provided by RMA).
• GOAL 1 Support SBR management by expanding the
  USDA SBR Information System to include an RMA
  website tool for documenting growers good
  management practices.
• GOAL 2 Broaden the scope of the SBR effort to
  include lesser-served, specialty legume crops and
  associated pests. The Agreement provides funds
  for sentinel plots, mobile scouting,
  aerobiological monitoring, diagnostics, outreach,
  and information technology tool development.

APHIS will share leadership with SRIPMC, i.e.
training on framework mechanics only for 2006,
website maintenance, and data archives.

ERS- 2nd study

• A DRAFT was received for review, October 2005,
  "The value of information from USDAs Soybean
  Rust Coordinated Framework What if you build
  it, and Rust does not come?"
• The document is under review and ERS aims to
  release it early in 2006. Initial findings are
