| Abstract/Contents: | "Bermudagrass contamination in zoysiagrass is problematic due to the lack of selective control options available. Field experiments were conducted to evaluate the effect of nitrogen fertilizer applied alone and in combination with trinexapac-ethyl (TE) on zoysiagrass competitiveness with two bermudagrass cultivars. Three sequential applications were made at 21-day intervals and included various combinations of nitrogen and TE. 'Tifway' and common bermudagrass differed in response to experimental treatments. Trinexapac-ethyl alone was the only treatment to result in decreased 'Tifway' spread throughout the study, relative to the nontreated. 'Tifway' bermudagrass spread was greatest from the 49 kg N/ha (1.0 lb/1000 ft2) and TE plus 49 kg N/ha treatments 12 weeks after initial treatment (WAIT). All nitrogen rates evaluated in this study reduced the ability of TE to suppress 'Tifway' bermudagrass spread in zoysiagrass. Conversely, common bermudagrass spread was equivalent among all nitrogen rates and TE applied alone. Trinexapac-ethyl plus 49 kg N/ha resulted in the greatest common bermudagrass spread 12 WAIT, equivalent only to TE plus 12.3 kg N/ha (0.25 lb/1000 ft2). 'Zorro' zoysiagrass color was most ideal (dark green) for the 49 kg N/ha and TE plus 49 kg N/ha treatments throughout the study. All treatments, other than the nontreated, produced acceptable zoysiagrass turf color (ā„ 6). Results of these studies indicate that nitrogen fertilizer applied with trinexapac-ethyl may reduce bermudagrass suppression." |
