Initial discussion focused on a review of the Jointed Goatgrass Initiative and it‘s effectiveness for the various groups. Those in the wheat industry generally felt there was a lot of information generated not just on jointed goatgrass, but also on wheat production, genetics, herbicide resistance, and other topics. Also, it was noted that outreach and extension efforts could be improved or intensified. Researchers found the initiative to be useful in securing funding for research on weed or crop ecology, which has been difficult to obtain. Researchers also felt initiative funding was not sufficient to support the research conducted without supplemental funding. However, all present agreed that the Jointed Goatgrass Initiative was extremely successful and there was a need to continue funding initiatives that focus on one or a few species of weeds in wheat production systems. The effectiveness of the Jointed Goatgrass Initiative Steering Committee was mentioned as key to its development and success.
A long discussion ensued with the participants listing current production problems that are obstacles to keeping wheat production systems sustainable. The discussion focused on management of diseases, insects, and weeds. Several different weed species including jointed goatgrass, feral rye, Italian ryegrass, Bromus sp., wild oats, Setaria sp. were discussed. It was decided that jointed goatgrass would not be listed as a justification for a new initiative, but research and extension efforts dealing with that species need not be excluded from a new initiative. Throughout the session it became apparent that it was important to keep the topics within a new initiative fairly broad. It was of an opinion that the steering committee format of the Jointed Goatgrass Initiative was an important reason for that program‘s success. The steering committee was able to provide solid decisions on funding and set direction in which to take research and extension programs. Rather than devote discussion time to specifics, it became apparent that the group should take a "broad brush" approach. The afternoon session of October 24 concluded with the agreement that a new initiative would be developed that would be titled, "Managing Invasive Weeds in Wheat." The group adjourned until the following morning.
Joe Yenish called the group to order on the morning of October 25. Discussion continued on which species to list in the proposed initiative. After a lengthy discussion and a poll of those present to determine which winter annual grass species were problems in the attendees states, it was decided that the Managing Invasive Weeds in Wheat Initiative should focus on, but not be limited to feral rye and Italian ryegrass. Again, it was pointed out that the success of the initiative would depend on a strong steering committee. It was felt that the new initiative should focus primarily on the Southern Great Plains, Northern Great Plains, Inter-mountain West, and Pacific Northwest Wheat production areas. Decisions to fund research or extension efforts outside of those geographic areas would rest with the steering committee. It was also noted that with the current Jointed Goatgrass Initiative ending in fiscal year 2005, a proposal to the National Association of Wheat Growers needed to be made at that organization‘s 2003 meeting in order to ensure no lapse period between initiatives. Arrangements were made to ensure the successful presentation of the Managing Invasive Weeds in Wheat Initiative to the National Association of Wheat Growers meeting in 2003.
It was decided that the next meeting of the WCC-077 project would be in Denver in 2003 as some time during the meeting of the American Society of Agronomy in that city. Phil Westra was elected chair of the WCC-077 project for 2003, Joe Yenish will take the position of Secretary.
