Brief Summary of Minutes of Annual Meeting

Agenda: Introduction Steven Slack Secretary election Old business 2003 meeting minutes Review 2003 activities Discussion of future committee activities New NC 504 proposal Next meeting Minutes: Introduction. Steven Slack provided an overview of the current status of the NC 504. Secretary election. Dr. Glen Hartman was elected as secretary of NC 504 Committee. Old business. Minutes of the February 2003 meeting were approved. Accomplishment included: soybean rust extension publications, extension meetings included St. Louis meeting with the American Soybean Association in January 2004. Discussion of future committee activities. Risk communication was discussed in terms of how to put survey results through the NPDN web site. Dr. Jim Steadman made comments on importance of surveying possible presences of soybean rust in Caribbean Islands in collaboration with local plant pathologists. Caribbean Islands is a possible pathway. The existing network has been established and surveys can be carried out with low cost. The risk of introducing SBR through seed importation from South America was discussed. It was considered that the risk is minimum with the latest information from the visit of Dr. A. Tschanz from Brazil. Information from this visit was presented by Dr. Matt Royer of APHIS. Surveys outside the US also were discussed. A subcommittee of Monte Miles, XB Yang, and John Rupe with Ray Schneider and Don Hershman as reviewers were to define protocols for surveys of different purposes. Motion was made and passed that the subcommittee would have something back to the group on protocols for surveys. A motion was passed for another subcommittee (Anne Dorrance, Mary Draper, Albert Tenuta, and Loren Giesler) to developing scouting cards. Dr. Slack, administration advisor, provided future options to the committee. These included: 1) To write a new proposal for establishment of a new NCR committee; 2) To renew the current committee for another year with a proposal to be submitted no later than September 1, 2004. Proposal for a new soybean rust committee was discussed. Committee unanimously passed to establish a rewrite committee. Objectives for the new committee were discussed and established. 1) To coordinate activities for early detection survey such as development of survey procedures. 2) To conduct risk communication; 3) to develop recommendations for SBR management for the US soybean production region. Next meeting location was discussed. Porto Rico was suggested for potential meeting location as this island may be a potential area for soybean rust over-wintering. Dr. Ray Schneider moved to thank Dr. M. Bonde, Dr. R. Frederick, and their staff for their excellent efforts in preparation of this meeting. He commented that the hand-on session in containment facility has put our committee members several years ahead of others in terms of disease identification and management. Committee Chair, X.B. Yang was to write the letter. Resolution was passed unanimously. Additional Notes from the previous day activities prior to the business meeting April 13 Dr. Yang, Chair of NC 504, called meeting to order at 8:30 am and made introduction. Dr. Bonde and Dr. Frederick made an introduction to the facility of USDA-ARS-Foreign Disease-Weed Science Research Unit (FDWSRU) and provided details for the visit of Level 3 Plant Pathogen Containment Facility. Participants were divided into two groups for the visit of the Containment Facility. Group 1 moved to Building 374 (Biosafety Level 3 Plant Pathogen Containment Facility) to learn first hand experience of soybean rust. Group two stayed for discussion and entered Containment Facility after completion of Group Ones visit. Discussion session was made for both groups. Following presentations were made: 1) Mary Palm, USDA-APHIS, on rust biology; 2) Dr. Matt Royer, USDA-APHIS on APHIS preparation of soybean rust entry; 3) Dr. Reid Frederick, USDA-ARS, on soybean rust research in FDWSRU; 4) Dr. XB Yang, on soybean rust epidemiology and risk assessment update; 5) Dr. Kent Smith, USDA-ARS, on management plan of soybean rust.

Extension 1. The 60 page soybean rust fungicide manual focusing on the very basics of fungicide application was developed. As of December 2005, 160,000 manuals were distributed in 20 states and Ontario, Canada. 2. Developed and maintained websites throughout the year concerning soybean rust, telephone hotlines, state extension newletters and more meetings. 3. In addition to the USDA website, NCDC202 members Assisted with American Soybean Association website to provide state specialists comment concerning soybean rust (www.soyrap.com). Research 1. Sentinel plot system for the south east and north central states was established and coordinated by Dr. Don Hershman (University of Kentucky) and Dr. Loren Giesler (University of Nebraska) working with the USDA team. Sentinel plots were scouted on a weekly and in some cases more frequently by representatives (extension educators) in each state. Soybean samples and findings (+/-) were sent to University Diagnostic labs and the State soybean specialists. Information from these findings was then uploaded to the USDA website (www.sbrusa.com) where the movement of soybean rust could be monitored through the season. The data collected from these plots was then used to develop and evaluate epidemiological models for the short term. 2. Spore sampling  J. Rupe, R. Schneider and J. Kurle evaluated spore samplers, spore collectors and verification techniques. Soybean rust spore movement was monitored and tracked through the summer. 3. Fungicide efficacy and timing trials- Participants in each state evaluated soybean rust fungicides for their impact on soybean yields during 2005. Only, Florida, Georgia and Alabama were able to evaluate the effects on soybean rust. 4. Evaluation of fungicides combined with insecticides and herbicides- Many states evaluated the impact of these combinations on crops. This was especially apparent in the north central region where aphids were a problem in some fields during 2005. 5. Impact of soybean rust fungicides on other soybean pest/pathogen systems was evaluated in both northern and southern production regions. Summaries of these results were prepared for winter extension meetings. 6. Evaluation of germplasm, commercial cultivars and soybean plant introductions and development of soybean populations with putative resistance to soybean rust 7. Evaluation/monitoring of overwintering (alternative) hosts for soybean rust NCDC was a major contributor/sponsor to the APS soybean rust symposium that was held November 15-16 in Nashville, TN. Summaries from the breakout sessions were written by NCDC 202 (http://www.plantmanagementnetwork.org/infocenter/topic/soybeanrust/symposium/)
