Brief Summary of Minutes of Annual Meeting

**PLEASE SEE ATTACHED "COPY OF MINUTES" FILE FOR INDIVIDUAL STATE REPORTS Summary of Minutes of Annual Meeting: Senyu Chen called the meeting to order and welcomed participants at 8:30 am at the University of Minnesota Southern Research and Outreach Center meeting room. The following day, Dr. Forest Izuno, the head of the Center, welcomed and provided an outline of the work carried out at the research and outreach center. The primary purpose of the meeting was to a) discuss development of a potential new North Central project; b) review the current status and participation in the NC1035 Project Objectives; and c) to report recent research results since the last meeting held in July 2009. Bayer CropScience provided a presentation and discussion of the new corn and soybean seed treatment product VOTiVO following the meetings. Planning session and review of project Objectives A) Discuss development of a potential new North Central project The committee members spent half a day in the morning of June 29 to discuss extensively soybean and corn nematode research requirements across each of the northcentral states and Ontario. The committee drafted a project outline including objectives, milestones, supporting outreach outputs and assignment of timelines and volunteers for preparing a written outline. Proposed draft of new project main objectives: Project: Practical Management of Nematodes on Corn, Soybeans and Other Crops of Regional Importance. Objective 1: Develop, evaluate, improve and integrate management techniques for plant-parasitic nematodes in the North Central Region to increase grower profitability. Objective 2: Determine the relationships among nematode population characteristics, crop injury and soil health. Objective 3: Develop tools for technology transfer for management of regionally important nematodes with special reference to soybean cyst nematode and corn parasitic nematodes. B) Review the current status and participation in the NC1035 Project Objectives Objective 1: To develop, evaluate, improve and integrate management techniques for soybean cyst nematode in the NC region to increase grower profitability. Discussion of the objective indicated that there was a general consensus that the majority of the committee are generating results for all of the sub objectives and that the members were on track in meeting the goals for this objective. Some of these data were published in the fall and spring prior to the next growing season. Several variety publication reports and web sites were presented in the state reports (note Activities section) and reviewed as outreach sources of information to the soybean producer. Additional research on the assessment of SCN population HG Types and other aspects of virulence was presented by the majority of the committee. There was considerable discussion of future need for research and potential participation in a proposed all state HG type survey. Biocontrol results from use of chicken waste and swine manure projects indicated some potential effects on SCN eggs (see State reports in Activites section). Research on interactions of SCN with other pests such as root lesion nematodes were included. Exploratory work is being conducted by several members of the group on the soybean and corn nematicide seed treatments that are being explored by several private companies. Objective 2: To apply the concepts of invasion biology to H. glycines epidemiology. Results Completion of Tier 1, 2 and 3 were outlined and a review of committee member participation indicated that the majority had completed Tier 1 protocol (Initial assessment of habitats for occurrence of H. glycines). Tier 2 protocol (Habitat conduciveness evaluation) Report of results from the cooperative project USDA-2009-35302-05261, Ecology of nematode-suppressive soils in Midwest soybean-cropping systems (see report in Activities) was presented. Outcome was to expand participation in a future study of suppressive soils as part of the work on evaluation of SCN habitat and epidemiology. The need to identify suppressive soils and levels of conducive field populations was emphasized. Committee consensus was that the feasibility of completing Tier 3 and 4 protocols was dependent on external funding. Funding was not obtainable by most members with the exception of the previously mentioned research group. The need for research funding was discussed and not resolved. Objective 3: To develop a decision-support database for management of H. glycines and other regionally important nematodes. A list of 716 SCN resistant soybean varieties available to Iowa growers was compiled containing information is available in hard copy or in PDF format on the Iowa State SCN web site. A limited discussion was held on creating a pocket size information card on how to sample soybean fields on one side and corn fields on the other side for nematodes. A guide for sampling corn nematodes is being developed in Wisconsin.

Accomplishments: Short-term outcomes: Data on H. glycines virulence phenotypes across the region were shared. Additional unbiased information on H. glycines resistant varieties and soybean yield in relation to SCN population density is available. Activities are described on the attached document listing State Research Activity Reports. Outputs are reported in the State Reports found in the Activities Attachment.
