| Abstract/Contents: | "There are approximately 15 million acres of improved pastureland in Texas where broad-spectrum weed control is an important component of bermudagrass (Cynodon dactylon) hay production. Although many broadleaf herbicides are available, annual and perennial grass control has been a recurring problem. In 2002, BASF Corp. developed Oasis herbicide which contains the active ingredients imazapic and 2-4,D. It provides broadleaf weed and annual grass control, however, bermudagrass injury from Oasis has been a problem that requires remediation. Research was conducted during 2001 and 2002 to evaluate the effects of Oasis on three popular Texas bermudagrass varieties at two locations. These included Coastal, Jiggs, and Tift on 85 bermudagrasses. Plot size was 8 ft. x 20 ft. and treatments were replicated four times and arranged in a RCB design. Treatments were applied with a CO2 backpack sprayer calibrated to deliver 20 GPA. Two herbicide application timings were evaluated at crop heights of 2-3 in. (stubble) and 6-8 in. (regrowth) within both varieties. Water or urea ammonium nitrate (UAN 32-0-0) were evaluated as herbicide carriers, and Oasis was applied at 2, 4, 6, and 8 oz./A. Dry Nitrogen fertilizer (70 lbs./A) was applied in the water carrier treatments to compensate for the 32% UAN applications in the other treatments. Three harvests were collected during the season, however, harvest intervals varied in the two years of the study due to variable weather conditions. All rates of Oasis consistently decreased crop yields in the first harvest, regardless of application timing, carrier or variety. Seasonal yields of Coastal bermudagrass were reduced from all rates examined. Similar results were shown with Tifton 85 and Jiggs bermudagrass. When Oasis was applied using water as the carrier, significant yield increases were shown, though numerically small. Carrier had no consistent effect in the Jiggs and Tifton 85 studies. Herbicide application timing was not a factor in any variety when Oasis was applied to crop stubble or 6-8 in. regrowth." |
