Glyphosate for Torpedograss and Bermudagrass Control1

  1. E. O. Beard

Abstract

Abstract

Ten experiments were conducted for control of torpedograss (Panicurn repens L.) and nine experiments were conducted for control of bermudagrass (Cynodon × magenissii Hurcombe) over a 5-year period. A single application of glyphosate (N-(phosphonomethyl) glycine) at the rate of 2.24 kg/ha controlled these two perennial weeds well. Rototilling within 4 days following the application reduced the effectiveness of the herbicide in controlling torpedograss. No reduction in phytotoxicity occurred when the interval was 7 or more days. Residual phytotoxicity of glyphosate at 4.48 kg/ha dissipated to permit normal germination and growth of perennial ryegrass (Lolium perenne L.) on a well-irrigated sandy soil when the interval between application and seeding was 10 or more days. Results from these experiments demonstrate the effectiveness of glyphosate for control of certain hard-to-kill rhizomatous weeds prior to establishing turf.
