Brief Summary of Minutes of Annual Meeting

The meeting of the NCERA 137 Soybean Diseases Committee was held in Washington D.C. at the Waterfront building from April 9-10, 2015. Dr. Heather Young Kelly welcomed those in attendance at 9:00am. Group introductions followed the welcome. Brief oral reports on the status of the soybean crop and prevalent diseases were given for each state with a member in attendance. Written reports were also provided and compiled into a PDF document. State reports can be found in the attached minutes document. The following presentations were given at the meeting: • Effective communication with congress-Kelleye Eversole • United States Soybean Board funded iPiPe Update– Scott Isard • NCERA Administrative Update-Steve Slack • USDA-NIFA Administrative Update-Dr. Marty Draper • USB Administrative Update-Dr. Kelley Whiting • SCSRP Administrative Update-Ed Anderson • Soybean Vein Necrosis Virus Update-Damon Smith • Management of Foliar Diseases of Soybean-Dr. Ahmad Fakoury • Updates to Fungicide Efficacy Tables-Dr. Kiersten Wise • Phytobiomes initiative-Kelleye Eversole • Cercospora leaf blight symptomology and impact on yield-Eduardo Chagas • Fungicide resistance in C. sojina aand S. glycines: Updates on Screening Results-Dr. Carl Bradley • Frogeye leaf spot fungicide resistance results from Mississippi-Dr. Tom Allen • Fungicide resistance in Tennessee populations of C. sojina-Dr. Heather Kelly • Bee Health – Preliminary results on fungicides detected from the Mid-South-Dr. Heather Kelly Business Meeting: Motion to approve the minutes from 2014: Dr. Doug Jardine moved for approval. Dr. Anne Dorrance seconded it. The motion passed with unanimous vote. Impact Updates: The group discussed state reports and impact statements and the need to highlight our accomplishments individually and as a group. Daren Mueller suggested that we change our state reports to streamline the process of writing the state reports and submitting them online. It was suggested that state reports should be one page long and highlight major impacts. Anne Dorrance suggested that the major impacts of the group be defined at the meetings for reporting purposes. Gary Bergstrom mentioned that we also need to remember to include interactions/collaborations in our impacts and reports. The group decided that personnel, disease conditions, production numbers, publications, and important state discoveries should be included in each single page state report. Secretary nominations: The floor was open for nominations for secretary of the NCERA-137 committee. Dr. Gary Bergstrom made a motion to appoint Dr. Damon Smith as the incoming secretary. Dr. Doug Jardine seconded and closed the nominations. Dr. Smith was unanimously elected by the group. Meeting Locations: Dr. Sam Markell discussed the potential for the NCERA-137 group to meet with the APS Rust Symposium. The rust group was interested in sites at New Orleans and Orlando. After talking with the group, Dr. Markell suggested that the rust symposium may be able to meet with SSDW in Pensacola FL. IF this is the case, the NCERA-184 group could also attend, thereby allowing attendance to the NCERA-184, SSDW, Rust Symposium, and NCERA-137 meetings at the same venue. Most of the meetings share attendees, thereby reducing/limiting travel. Dr. Tom Allen mentioned that SSDW is held on March 9-10, 2016. It was proposed that March 7-11 would be ideal to hold the entire string of meetings. Another option was to have the meeting the first two weeks of February. Dr. Dorrance moved that we attempt to meet with the rust symposium in 2016. Doug Jardine seconded. There was unanimous support for the motion. Dr. Markell will contact APS and Dr. Kleczewski about organizing the meeting in the upcoming weeks. Dr. Kelly moved to close the meeting and the entire group unanimously seconded it.

Objective 1: Foster collaborative research and information exchange on soybean diseases among scientists in the north central region including soybean breeders and entomologists that will lead to improved disease screening protocols, additional sources of disease resistance, and ultimately improved host resistance. Accomplishments: a) Members of NCERA 137 voted to hold the 2015 meeting in conjunction with the APS rust symposium. The 2015 meeting will likely not only be help with the rust symposium, but also the NCERA 184 wheat disease group and the Southern Soybean Workers group (SSDW). This will foster additional information and idea exchange, collaboration, and improve participation. b) Discussion at NCERA 137 has resulted in participation in new and existing projects by new members of the group. Projects include white mold fungicide efficacy, Soybean Vein Necrosis Virus, and Stem Canker epidemiology and management. Objective 2: Evaluate the impacts of changing production practices such as earlier planting dates, new sources or resistance, increased use of fungicides and fungicide seed treatments, and other new or improved crop production technologies on soybean diseases. Accomplishments: a) Members of NCERA 137 are working collaboratively to update produce guides for seed treatments and foliar fungicides in soybean. These guides can be used by growers and agriculture professionals to select the product that will best suppress a given root or foliar disease in their region. b) Members of the group have documented increased numbers of strobilurin resistance in the Frogeye leaf spot pathogen. In 2014, additional resistant isolates were identified in several new counties and states, such as Virginia and Mississippi. Objective 3: Develop research projects to study the ecology and epidemiology of soybean diseases important to the north central region. Accomplishments: a) NCERA 137 members are working collaboratively on multi state research projects focused on stem canker, soybean cyst nematode, Sclerotinia white mold, Soybean Vein Necrosis Virus, soybean rust, frogeye leaf spot, and and charcoal rot. b) A survey of P. sojae has been completed in a region of the Midwest, which has improved our understanding of this pathogen and its management. Interactions via NCERA-137 have allowed this survey to continue and expand. Objective 4. Improve knowledge transfer about soybean diseases and their management in the North Central Region to researchers, Extension faculty, producers, and the agribusiness community through the use of websites, podcasts, and other new technologies as they become available. Accomplishments: a) Members of NCERA 137 were involved in the production of over 78 web based extension outreach materials including blogs, videos, electronic materials, and factsheets. b) Members of NCERA 137 continue to provide new webcasts for the Focus on Soybean section of Plant Management Network. c) Members of NCERA 137 continue to develop a farmer friendly version of the soybean disease compendium. Objective 5. Continue to monitor any new or emerging pathogens in the north central region and develop appropriate responses to their emergence as they appear. Accomplishments: a) Members of NCERA-137 have collectively documented the increase in Frogeye leaf spot, Cercospora leaf blight, and Septoria brown spot, which impact management recommendations and therefore, soybean productivity. b) Members of NCERA-137 continue to work together to evaluate and develop pest information platforms for soybean rust, soybean vein necrosis virus, and strobilurin resistant frogeye leaf spot. c) It was determined that stem canker may be an emerging issue in parts of the north central region. Members on the group are working on projects to assess and evaluate this disease, its impacts, and management.
