CONSERVATION FARMING
UPDATE - December 1995 Northwest Jointed Goatgrass Conferences in February 1996
Growers
and Ag support personnel in Idaho, Oregon and Washington are encouraged
to attend one of three conferences on jointed goatgrass scheduled across
the Northwest in February 1996. The conferences have been developed
as part of a cooperative research and education effort on jointed goatgrass
control in the western U.S.
This winter annual grass weed has spread rapidly over the past 20 years and now infests approximately 7.5 million acres of winter wheat cropland in the western U.S. It can cause serious economic impacts. Populations of 5 plants per square foot can reduce wheat yield by 25% and yield losses over 50% are common in infested fields. It also reduces net grain weight and milling quality, increases dockage costs and prevents marketing of wheat as certified seed. The one-day conferences will provide in-depth information on the extent and management of the jointed goatgrass problem. The programs will be region-specific, addressing the jointed goatgrass problem under the major winter wheat production systems in the region surrounding each conference location. Conference registration begins at 8:30 AM with the program from 9:00 to 3:45 PM. Program topics at each conference location will generally include: overview of the problem, grain marketing policies, biology, genetics, population dynamics, removing jointed goatgrass seed from wheat, competitiveness of wheat cultivars, mechanical and chemical controls, integrated management strategies, current research and a producer panel. Continuing education credits for Certified Crop Advisers are being requested. Pesticide applicator recertification credits will also be available in . Preregistration fee is $15, including lunch. On-site registration will be approximately $25. The conference locations, dates and contacts for information and registration forms are as follows:
