Brief Summary of Minutes of Annual Meeting

The 20th annual meeting of NCR-137 was held at the Doubletree Paradise Valley Resort in Scottsdale, AZ on March 2 and 3, 2005. The meeting was held in conjunction with the Southern Soybean Disease Workers (SSDW) Meeting and the NC504/NC202 meetings. A joint general session on soybean rust was held on March 2nd. Presentations were made by Ray Schneider, Louisiana State University, Glen Hartman, USDA-University of Illinois, Reid Frederick, USDA-ARS, Monte Miles, USDA-ARS, Greg Shaner, Purdue University, Kelly Whiting, Delta Pine Land Company, Marty Draper, South Dakota State University, X.B. Yang, Iowa State University, Kitty Cardwell, USDA-CSREES, Coanne OHern, USDA-APHIS, Carrie Harmon, University of Florida-SPDN, Anne Dorrance, Ohio State University, Loren Giesler, University of Nebraska and Jim Kurle, University of Minnesota. A morning session for NCR-137 was convened at 8:30 am on March 3. Anne Dorrance provided an update on SoyCAP (Soybean Coordinated Agricultural Project). It deals with soybean translational genomics. The project will target the soybean genome for rust resistance genes. Soybean genomics will compete against other genomic projects such as wheat, barley and rice. As an example, rice received block grants in the amount of 20 million dollars last year. There will be a writing workshop for the grant at the end of May. Information on who will be on the writing group should be sent to Anne. Laura Sweets distributed the soybean disease loss figures for 2004. The rest of the morning session was taken up by state reports. Detailed state reports were presented by Wisconsin, Nebraska, Pennsylvania, Ohio, Illinois, Missouri, North Dakota, Iowa, South Dakota, Minnesota, Michigan, Kansas and Ontario. Following lunch, Chair Anne Dorrance called the business meeting to order. Berlin Nelson moved to approve the minutes of the 2004 meeting as distributed by e-mail and the motion was seconded by Loren Giesler. The motion was approved by unanimous voice vote. Participants and guests introduced themselves and gave brief updates as to retirements, position vacancies and recent hires within their departments or units. Steve Slack, administrator advisor for NCR-137 provided a brief update. The presidential budget was the topic of a Washington, D.C. meeting earlier in the week. The president is proposing to reduce formula funds, water quality, food safety, and other targeted funds from the budget. This would be offset by an increase of $75 million in state experiment station competitive grants. The Board of Agriculture has made reinstatement of the formula funds a top priority. There is hope that most, but probably not all of the funds will be restored. Steve suggested that this may be a trial balloon for future years. For more specific state information, it was suggested to visit the NASULGC (National Association of State University and Land Grant Colleges) website @ http://www.nasulgc.org. The twelve north central states will lose $54 million directly with additional losses from leveraged state funds. Positions affected would include 203 faculty, 263 staff, 175 other, and 574 graduate students. There is a push to refer to these funds as base, as opposed to formula, so that they do not sound like handouts. As an example, the loss of base funds would equal about 25% of the agriculture funding in Ohio. NCR-137 is current and up to date on reporting. We were reminded that we have 30 days to report the minutes and 60 days for the annual report. It was noted that we need to designate the committee as either a NC-CC (coordinating committee) or NC-ERA (extension research area) category. Discussion of the 2006 meeting site occurred. Sylvia Cianzio (IA) had previously arranged for us to meet in Puerto Rico in 2006. In light of the introduction of soybean rust into the United States, the consensus opinion of participants is to meet with SSDW again in 2006 instead, maybe in February or early March. Efforts will be made to find a date. The American Phytopathological Society (APS) will be contacted to see if they would be willing to postpone their proposed National Soybean Rust Symposium currently scheduled to be held on November 15-16, 2005 so that it could also be held in conjunction with the NCR-137/SSDW meeting. The next item of business was the election of the secretary. After some discussion, Erick DeWolf volunteered to be secretary for 2006. He was accepted by a unanimous voice vote. Doug Jardine will advance from secretary to be the chair. Berlin Nelson moved that NCR-137 be designated as an NC-ERA committee. Erick DeWolf provided the second. There was no discussion. The motion was unanimously approved. NRC-137 would like to thank members of SSDW for their assistance in making arrangements for the meeting. Being no more business, Berlin Nelson moved to adjourn the meeting and Loren Giesler seconded it. Following approval the meeting was adjourned at 2:30 pm.

Soybean Rust 1. Soybean rust was found in 2 counties in southeast Missouri in late 2004 2. Minnesota and South Dakota took the lead nationally in developing Section 18 emergency request templates for additional fungicides to be used to manage soybean rust 3. Ohio State led cooperative efforts to provide preserved rust infected leaf specimens to extension specialists for use at winter seminars and a national extension publication titled, Using Foliar Fungicides to Manage Soybean Rust. 4. Worked cooperatively with NC504/NCD202 Soybean rust committee to develop a joint annual meeting Sudden Death Syndrome 1. Several states reported high severities in 2004 with a new record report in NE 2. Regional variety trials were planted and evaluated 3. Ongoing research in the region includes identifying mycoviruses of Fusarium solani f. sp. glycines that may be associated with pathogenicity and using a green fluorescent protein gene to study the differences between partially resistant and susceptible cultivars Sclerotinia White Mold 1. A multistate North Central Soybean Research Program project continues. A project meeting was held in New Glarus, WI 2. High levels of white mold were reported in several states 3. Ongoing research in the region includes studying the role of light in disease development, identifying mechanisms of host resistance for germplasm improvement, and evaluating novel antifungal synthetic peptides. Phytophthora Root Rot 1. Pathotyping of field isolates from across the region is nearly complete 2. Metalaxyl resistance testing has indicated that most field isolates remain susceptible to the fungicide Charcoal Rot 1. Illinois, Mississippi and Kansas are cooperating on a North Central Soybean Research Program project to improve germplasm resistance to charcoal rot. 2. New greenhouse screening techniques have been developed at Illinois and field evaluations are being conducted at several locations among the cooperating states. Bean Pod Mottle Virus 1. Nebraska, Ohio and South Dakota have ongoing programs studying this bean beetle vectored virus. Studies center around evaluation of cultivars for resistance and reducing losses through the use of insecticides to manage the vector
