Brief Summary of Minutes of Annual Meeting

The annual meeting of NC-227 was held at the Hacienda Hotel, Puerto Vallarta, Mexico on 19-21 March 2002. This meeting site and date were selected to facilitate interaction with scientists from INIFAP as well as to allow tours of sorghum ergot research plots by several member scientists. NC-227 Administrative Advisor Dale Vanderholm discussed status of funding and organizations impacting NC 227 activities. He discussed the NC 227 termination date of 30 September 2004 and a need to plan for continuation or direction change at the next annual meeting. There was discussion and general agreement that industry representatives should be invited to become full members of the committee. The inclusion of INIFAP as part of NC-227 meetings was considered to be very positive and should continue. The next NC-227 meeting was tentatively scheduled to be held in association with the Grain Sorghum Research & Utilization Conference (NGSP/SICNA) on February 16-19, 2003 in Albuquerque, NM to discuss the future of this regional committee.

Research progress reports were given by scientists from Kansas State, Nebraska, Texas A&M, and INIFAP.

The committee ratified the appointment of Jeff Pedersen to become Chair of NC-227 for the next year. Charlie Rush of the Texas Agricultural Experiment Station Texas A&M University was elected NC-227 secretary for 2002-03.

The meeting was adjourned at 1:30 PM on 20 March 2002 and attendees embarked on the field tour of breeding nurseries and commercial seed production fields.

Accomplishments

Scientists from the U.S. and Mexico presented research progress in diverse areas including pathogen biology and survival, host:pathogen:environment interactions, development of host plant resistance, predictive modeling of ergot occurrence, chemical control, and the development of field and other techniques to facilitate research in these areas. The information exchange between Mexican and U.S. scientists and representatives of the sorghum industry was especially productive in providing a comprehensive knowledge about sorghum ergot which now commonly occurs in both countries. Continued international sharing of ergot research progress among all components of the sorghum industry will promote development of appropriate control methods and adoption of the most rational governmental regulations concerning sorghum ergot and seed movement within and between countries. This is especially relevant to countries in the western hemisphere already affected by sorghum ergot but dissemination of this information through publication and other means may also prevent or at least delay introduction of C. africana into other countries where not currently present.
