Brief Summary of Minutes of Annual Meeting

Greg Tylka called the meeting to order and welcomed participants at 8:00 a.m. on March 5th, 2008 in Tampa, Florida. The meeting was held one day before the 4th National Soybean Cyst Nematode Conference sponsored, in part, by NC 1035. The meeting, convened to report on activities during 2007, was delayed beyond the scheduled December date to coincide with the SCN conference. State reports were presented with the information organized by project objectives: 1.) Develop, evaluate, improve, and integrate management techniques for SCN in the NCR to increase grower profitability, 2.) Determine and apply the concepts of invasion biology as revealed by SCN epidemiology, 3.) Develop decision-support data bases for management of SCN and other regionally important nematodes. Relating to objective one was discussion about the availability and efficacy of soybean varieties to SCN, SCN resistance genes and the difference among cultivars that share the same source of resistance, the range of virulence phenotypes of SCN for development of resistant varieties, methodology appropriate for characterizing SCN populations, tillage and the impact of soil disturbance on suppression of SCN by fungal antagonists, the interaction of SCN with other pests and pathogens, and soil amendments including manure and cover crops for SCN management. Discussion for objective two focused on surveys for SCN conducted during the past year and the methodology for tier 2 evaluation of soils for conduvciveness to SCN. Progress of SOPs for screening resistant lines of soybean to SCN and an index of commercial varieties resistant to SCN were discussed as pertinant to objective three.

Accomplishments

Short-term outcomes: Improved use of soybean varieties resistant to the soybean cyst nematode (SCN) resulting in higher yields and decreased population densities of SCN. Outputs: Publications as reported in the "Publications" section Activities: Objective One: - Virulence profiles for SCN populations were conducted in Illinois, Minnesota, Ontario, and Wisconsin. - Host resistance for managing SCN was evaluated in Ontario, Kansas, Tennessee, Michigan, Minnesota, Illinois, and Iowa. - Selection pressure imposed by continuous planting of SCN-resistant varieties was studied in Arkansas, Kansas, and Wisconsin. - The impact of soil disturbance and tillage on SCN was determined in Indiana, Minnesota, and Vermont. - Soil amendments for the management of SCN were evaluated in Ontario and Minnesota. - The interaction of SCN with other pests and pathogens was studied in Iowa, Minnesota, and Wisconsin. Objective Two: - Surveys for SCN to identify candidate fields for Tier II activities were conducted in Illinois, Michigan, Minnesota, Nebraska, North Dakota, Ontario, and Wisconsin. Objective Three: - An SOP for screening resistant lines to SCN was developed. - Lists of SCN-resistant varieties available commercially were compiled by Iowa and Tennessee. Milestones: Developed standard format for reporting data relating to objective one.

Impacts

Information from this project, disseminated in reports, presentations, and web sites, helped the soybean industry assess the impact of SCN on soybean production and the importance of planting SCN resistant varieties.
Characterization of virulence for field populations of SCN across the region provided insight to producers and researchers about variability among geographic isolates and the importance of integrating different management tactics for SCN control.
Data on novel approaches as well as established practices such as tillage increased the ability of producers to develop a management plan to maximize yield and minimize reproduction and build-up of SCN.
