| Abstract/Contents: | Presents a study with the following objectives: "1. Determine the optimum rate for using Basamid to control Poa annua in a fairway renovation project. 2. Determine the optimum method for using Basamid to control Poa annua in a fairway renovation project. 3. Determine the delay after application that is needed to safely seed creeping bentgrass." Results for the May experiments include that "all May experiments at both University of Illinois and Purdue University produced poor results. We conclude that the spring appears to be a poor time to use Basamid because no treatments produced acceptable control of the established turf, nor acceptable control of Poa annua when germinated on the mist benches. We attribute this to a number of factors, primarily to the strong winds following application. Air temperatures reached 80-90°F for 3-5 days following application and were accompanied by 30-35 MPH winds. We presume that these conditions caused the Basamid to volatilize too quickly reducing its effectiveness." Results for the August experiments include that "August experiments produced much more promising results at both locations with a number of Basamid treatments providing excellent control. Basamid Rate Experiment. Basamid applied at 300 lbs/A and higher produced 95% or better cover of creeping bentgrass when rated 18 Nov at Purdue which was about 3 months after application. This compares with about 65% creeping bentgrass cover produced by the industry standard Roundup treatment. All Basamid treatments dramatically reduced the number of viable Poa annua seeds compared to Roundup, but it appears that 225 lbs/A may be the threshold rate for significant control of Poa annua seeds. Soil Preparation Experiment. Judging from the results in rate experiment, the Basamid rate used in this experiment was so effective that meaningful differences among soil preparation treatments were not observed. Regardless, it appears that there is no meaningful difference between applying Basamid prior to or after application. This is favorable because Basamid can most practically be applied only after aerification in a golf course renovation setting. As expected there appears to be a signficant difference between aerifying only 1X and aerifying 3X. The increased number of aerification holes in the 3X treatment allowed the Basamid to penetrate the soil better, plus the increased soil on the surface produced a better 'seal' holding the Basamid gas in place. In a practical sense, increased aerification will also improve the seed-soil contact resulting in improved establishment of the desirable grass. The most effective treatment for reducing viable Poa annua seed was Basamid applied after 3X aerification. It appears that it is safe to seed creeping bentgrass 5 days after Basamid application." |
