Brief Summary of Minutes of Annual Meeting

The annual meeting of WERA-97 was held in conjunction with NCERA-184 Fargo, North Dakota from June 12-14 at the Holiday Inn. The WERA-97 business meeting was held on Monday June 12 and consisted of State reports and a discussion future meeting sites. State reports were presented for California, Idaho, Kansas, Minnesota, Montana, Nebraska, North Dakota, Ohio, Oregon, South Dakota, and Washington. Discussion of powdery mildew, loose smut, aerial versus ground application of fungicides, and use of reduced fungicide rates followed the state reports. A social was held in the evening at the home of Marcia McMullen. The joint general meeting was held during the morning of June 13 and consisted of presentations by Sam Markell on Stripe Rust, Yue Jin on UG99, the new race of Black stem rust, Tika Adhikari on wheat leaf diseases, Tom Allen on Karnal bunt, Alan Dyer on wheat root rots, Stephen Neate on Speckled leaf blotch of barley, Bill Bockus provided an update on the status of the APS Wheat Disease compendium revision, and Erick DeWolf discussed a proposal for a National Wheat Disease Information Network. A field tour of area research plots at the Prosper research farm and local farmer Bill Hejl's Bonanza farm was held in the afternoon. A joint social with the APS Central Division was held in the evening at the Holiday Inn. The NCERA-184 Business meeting was held in the morning of June 14 to discuss future meeting sites and special topics for discussion in 2007. An invitation was extended by WERA-97 Administrative Advisor Tim Murray for NCERA-184 to meet jointly with WERA-97 in Idaho Falls in 2007 and accepted by Jeff Stein, Chair. The meeting was adjourned at 8:00 am. There were a total of 32 participants at the meeting representing 15 states. Of these, 29 are from the public sector and 3 are from the private sector. Letters of invitation sent to individuals filling positions on small grain pathology in the western region following the 2005 meeting resulted in three new participants from Idaho, Nebraska, and South Dakota with interest expressed by a newly hired individual in Utah.

Joint meeting. Although discussed for several years, this year's meeting represents the first formal joint meeting of the western and eastern multi-state research and extension committees for the control of diseases of small cereal grains. As such, communication among scientists in different geographic regions of the country was improved, as well as between established individuals and those in the early stages of their careers. As a result of broad representation present at this meeting, discussion of potential projects to establish a method for distribution of information about small grain diseases nationally were begun. 2007 Meeting Site Selection. As a result of the successful interaction at this meeting, participants decided to meet jointly again in 2007 in Idaho Falls, Idaho. This venue will provide the opportunity to visit the USDA Small Grains Collection in Aberdeen, ID and interact with USDA personnel associated with this collection. Discussion of another joint meeting in 2009 in the eastern US also took place, but a decision was postponed until next year. Revision of the Compendium of Wheat Diseases. A team of five wheat pathologists (most of who belong to WERA-97 or WERA-184) and one entomologist was assembled in 2005 to coordinate revision of the Compendium of Wheat Diseases published by APS Press. To date about 148 of the 160 revised chapters have been submitted and are in the process of being edited. The entire manuscript will be submitted to APS by November. In addition, the List of Common Names of Wheat Diseases is being revised in conjunction with this project. This collaborative effort between NCERA-184 and WERA-97 is a significant accomplishment since it has been 18 years since the last edition was published. Summary. This group continues to fulfill the objectives of communicating and coordinating research activities among its members, which is largely composed of public sector scientists but also includes regular participation by members of the private sector. Discussions at this annual meeting help inform its participants of potential new problems, and new approaches to the control of long-established problems.
