Establishment of Centipedegrass and St. Augustine Grass with the Aid of Chemicals1
- B. J. Johnson2
The establishment of Centipedegrass (Eremochloa ophiuroides (Munro) Hack.) and St. Augustine grass (Stenotaphrum secundatum (Walt.) Kuntze) is often slow because weed competition may be severe. An experiment was conducted to determine the effects of single and repeated treatments of atrazine (2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine) and simazine (2-chloro-4,6-bis(ethylamino)-s-triazine) on the establishment of these two species. Single treatments of simazine and atrazine at 1.12 kg/ha applied immediately following sprigging satisfactorily controlled grassy weeds and increased percent ground cover. Except for atrazine on St. Augustine grass, herbicide treatments caused early growth retardation without reducing ground cover at the end of the season. The desirability in appearance of the turf was not generally affected by either chemical at the rates used.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
