| Abstract/Contents: | "The efficacy of glyphosate in controlling bermudagrass (BG) (Cynodon dactylon L.), Guineagrass (GG) Panicum maximum Jacq.) and purple nutsedge (PN) (Cyperus rotundus L.) was determined when the herbicide was used alone or with adjuvants: Frigate, LI-700, or VPG in a volume of 378 liters of water/ha. No loss of BG control was noted as the glyphosate level was lowered from 4.5 to 2.25 kg.ha-1 with Frigate added, but control decreased with VPG or no adjuvant addition (LI-700 was not used). No reduction in control of PN was observed when Glyphosate amount was lowered from 3.4 to 1.7 kg.ha-1, provided LI-700 was present in the spray solution. With Frigate, VPG, or no adjuvant, however, the degree of PN control was less at 1.7 than 3.4 kg.ha-1. Frigate, LI-700, and VPG were equally effective in improving glyphosate efficacy on GG when the herbicide was used at 3.4 kg.ha-1, but the adjuvants had no effect at the herbicide level of 1.7 kg.ha-1." |
