Brief Summary of 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.

Brief Summary of Minutes

Accomplishments

NC504 was established to identify information needs, and to coordinate research, education and extension activities across states and regions. The objectives of this project were the following:<br /> 1. Develop survey procedures<br /> 2. Develop educational materials for soybean rust identification<br /> 3. Identify potential impact of soybean rust to soybean<br /> 4. Identify and evaluate tactics for soybean rust control, and communicate results with the user community<br /> 5. Identify and prioritize information and research needs<br /> <br /> The primary accomplishment of the NC504 committee was diagnostic training for soybean research and extension pathologists, which then led to the detection of soybean rust in Louisiana by Dr. Ray Schneider. A PowerPoint presentation on these activities can be found at: (add link)<br /> Education of soybean pathologists at NC504  St. Louis meeting, February, 2003<br /> Education of soybean pathologists at NC504  Ft. Detrick, April 2004. Training at Ft. Detrick was imperative to the success in detecting soybean rust by Dr. Ray Schneider on a research farm in Louisiana.<br /> <br /> The next phase was to develop tools for training and education. A grant was received by the NC504 community through USDA-CSREES Smith-Lever Special Needs funds to develop the following:<br /> 1. Soybean Rust Identification Card  this card depicts the primary diagnostic symptoms and signs of the soybean rust fungus on soybeans, and contrasts these with other soybean foliar diseases in a 4-color brochure. USDA-APHIS paid for printing 500,000 cards and NCSRP paid for printing of an additional 275,000. These were distributed at soybean rust training sessions throughout the US during December, 2004-March, 2005. This effort was led by Dr. Loren Giesler, (University of Nebraska) and Dr. Anne Dorrance (The Ohio State University). All but 22,000 have been distributed (March 2005) <br /> 2. Preserved soybean rust infected leaves  these leaves were collected and embedded in a resin in South Africa from a protocol developed by R. Schneider in Louisiana before soybean rust arrived in the US. Both resin and personnel were sent to South Africa to make these leaf mounts. <br /> 3. Soybean Rust Fungicide Guidelines Bulletin. Without US data, only guidelines can be provided based on both the USDA Efficacy trials run by Dr. Monte Miles (USDA-ARS, Univ. of Illinois) and company data used to submit requests for Section 18 emergency exemptions. This 50+ page manual was edited by Dr. Anne Dorrance (The Ohio State University), Dr. Martin Draper (South Dakota State University) and Dr. Don Hershman (University of Kentucky). Contributions and comments came from more than 20 Land Grant Universities and the Ontario Ministry of Agriculture. Topics covered include: economic importance and general biology of the soybean rust fungus, risk assessment in making fungicide decisions, fungicide basics, fungicide use strategies for soybean rust management, fungicide application basics, using skip rows to facilitate late-season fungicide applications, pesticide basics and information charts, as well as reference articles and links to more information.<br /> 4. A fungicide decision making chart was developed as a framework that each state could adapt to its specific growing conditions, maturity groups, and other soybean diseases that require fungicide applications. This has been utilized by many states and adapted to each region.<br /> 5. A List serve was created for communication among soybean pathologists. This has been very beneficial because ideas about management, fungicide availability, and wording of fungicide labels are constantly changing. Dr. Don Hershman at the University of Kentucky is the host of the list serve.<br /> 6. Continue to train ourselves via Ft. Detrick and Brazil trips. Trips to Brazil sponsored both USDA and industry took place mainly during February 2005. This allowed University Extension Specialists to observe epidemics, to gain experience in field identification of the disease, to learn about how the disease is managed there, to critique fungicide efficacy trials, and to learn about different disease rating systems that are used in a country that now has 3 years of experience with soybean rust.<br /> 7. Extension specialists conducted many training sessions during 2005 for education of certified crop consultants, county extension educators, and soybean producers.<br /> <br /> From 17 of the 18 member states in NC504, representing 55,037,600 soybean production acres, a total of 61 train the trainer type sessions were held with approximately 3,926 in attendance. Train the trainer type sessions were primarily focused at county/parish extension educators and certified crop advisors. In addition, many of the extension faculty also directly gave presentations to producers, 655 producer meeting with approximately 72,026 in total attendance. <br /> <br /> Eleven of the eighteen states have developed websites for soybean rust as it directly impacts their state. PowerPoint presentations are available at many of these websites for trainers to download and all states have a task force which will respond to soybean rust. In addition to the Extension specialists, USDA personnel (M. Miles) gave 31 talks to 12,000 producers. A regional teleconference was held on June 29, 2004 to 100 locations in 11 of the 12 north central states.<br />

Impact Statements

  1. The cost of a single fungicide application will range from 10 to 20 dollars per acre and up to three applications may be needed in some regions of the U.S. Providing guidelines for the timing of this application and a coordinated warning system for application timing has evolved with many members in this group. This will allow producers to have the maximum potential for return on their investment of treatment. In addition, educational efforts of this group will also keep producers from applyi
  2. Educated 87,952 producers, county extension educators, certified crop consultants on detection, identification, and management of soybean rust directly by soybean extension specialists throughout the Midwest. This does not include the multiplier effect from county extension educators and crop consultants who then take presentations from soybean specialist and then deliver that material in state.
  3. Developed and disseminated training tools for educating growers on detection and identification of Asian soybean rust through the preserved soybean infected leaves as well as the soybean rust identification card.
