None of the treatments caused any visual crop injury. Downy brome control ranged from 79-91% on the 5/8/07 rating. All of the treatments with the exception of Olympus by itself controlled tarweed 63-93%. The addition of MCPA to the treatments generally increased control of tarweed 10-15%. The addition of Cleanwave and MCPA did not affect downy brome control. Plots were harvested 7/20/07 with a 'Hege' small plot combine.The harvested grain was further cleaned with an 'Almaco' air cleaner. The grain was thenweighed, test weight determined and yield calculated as bu/A using a standard 60 lb/bu testweight. There were no significant differences in test weights between any of the treatments.The untreated control plots had the lowest yield at 56 bu/A, followed by Olympus by itselfat 78 bu/A. The other treatments averaged 88-96 bu/A.
