Brief Summary of Minutes of Annual Meeting

Brief minutes for the joint WERA11 and NCERA221 multi-state coordinating committee meeting, 2022

Chair Keenan Amundsen (Host State Nebraska) called meeting to order at 8:15 am.

Amundsen provided a brief introduction and discussed the motivation, timing, and location for the meeting. The purpose and importance of the multi-state coordinating committees was also discussed by the committee. Amundsen noted that several members planning to attend the meeting were unable due to travel and other delays. The planned Scandinavian Airlines System strike for that week negatively impacted attendance.

Attendees introduced themselves and described their role at their respective locations.

Nick Christians (Iowa State) presented the historian report, appended to the bottom of these minutes. Christians discussed the importance of maintaining the historian records and briefly discussed recent past meeting locations and planned locations for 2023. Meeting locations for the next calendar year were discussed separately for WERA11 and NCERA221. Alec Kowalewski (Oregon) will host WERA11 and Deying Li (North Dakota) will host NCERA221 in 2023; Kowalewski and Li will serve as chairs in 2023 for their respective multi-state coordinating committees. Locations for 2024 have not yet been determined.

Incoming chairs serve as secretaries in the current year, and Li took minutes for the meeting.

Dr. Aaron Patton (Indiana), prior to the meeting shared that his term as NCERA221 representative to the National Turfgrass Evaluation Program Policy Committee was coming to an end and requested that a new representative be selected to serve. Amundsen solicited nominations for the position prior to and during the meeting; Deying Li (North Dakota) and Doug Soldat (Wisconsin) were nominated. Since there was not quorum of NCERA221 members at the meeting, it was determined that the election will be handled virtually, coordinated by Amundsen following the meeting.

State representatives were asked to use a consistent format for reporting their multi-state activities. David Gardner (Ohio State) shared a report format template prior to the meeting that was used for individual annual state reporting by NCERA221 and Amundsen shared a report template for WERA11.

Representatives introduced their programs, summarized their undergraduate and graduate programs, and discussed regional and collaborative research projects. More details are available in the 2022 WERA11 and NCERA221 annual reports.

Prior to the meeting Gardner requested to share information on an ongoing organic crabgrass control trial with a plan to receive research data at the end of this season followed by analysis and preparation for journal article submission, planned for Crop, Forage, and Turfgrass Management.  He will send cooperators information in September requesting their data. This led to further discussion on failures in pre-emergence crabgrass control, and subsequent discussion on developing growing degree day models or other prediction tools to optimize herbicide application timing in the region.

Another study that received attention was the use of biocontrols for pest control in turf. Dave Smitley (Michigan State) electronically shared research on the use of biocontrols for Japanese beetle with the committee. Zhiqiang Cheng (Hawaii) described his research on the use of biocontrols and potential applications in the region.

Adjourned at 11 am.

Collaborative projects initiated to optimize best management practices, establishment, and cultivar selection for growing turfgrasses subjected to winter stress.

Regional research supported by more than $16 million, contributing to enhanced turfgrass management.

Turfgrass breeding lines were advanced with a goal to develop regionally adapted germplasm and cultivars

Use of biological and chemical control of turfgrass pests were tested throughout the region informing turfgrass managers about pest control strategies

Several water deficit and salt stress studies were done to identify new germplasm sources or management practices to optimize turfgrass systems water management in arid parts of the western region

Multi-year carbon sequestration project was continued to test the ability of turfgrasses to sequester soil carbon
