| Abstract/Contents: | "Celsius (dicamba + thiencarbazone-methyl + iodosulfuron) was evaluated in 2009 to determine its' effectiveness for controlling dallisgrass (Paspalum dilitatum), dichondra (Dichondra carolinensis), slender aster (Aster subulatus), and sprawling horseweed (Calyptocarpus vialis). All are common weeds in central Texas turf grass. When Celsius was applied POST to dallisgrass at 4, 5.33, and 6.0 oz./A on 4-6 inch perennial plants, initial activity (26 DAT) ranged from 38 to 70 % control, but dissipated to 7 to 25% by the 55 DAT rating date. When applied POST to dichondra at rates of 4 and 5.33 oz./A, control at the 35 DAT rating ranged from 92 to 95%. This activity diminished by 71 DAT to 68 to 88% control, however, sequential applications applied at the 71 DAT evaluation date elevated control back to greater than 99% by late season. Celsius provided excellent season-long control of slender aster when treated at rates ranging from 2.46 to 5.33 oz./A. Applications were made when the slender aster was 2-3 in. and in the leafy stage of growth. At 14 DAT, control ranged from 75 to 87%, but increased to 99 to 100% by the 42 DAT rating date and was maintained at this level throughout the season (> 90 DAT). Celsius provided good-excellent (72 to 88%) control of sprawling horseweed when applied to 1-3 in. plants at rates ranging from 4 to 6 oz./A and evaluated 26 DAT. By 55 DAT, control had increased to greater than 93% from all treatments. In a separate study conducted on sprawling horseweed, Celsius efficacy was evaluated when applied alone at 3.97 and 4.92 oz./A ,with 0.5% or 1.0% (v/v) of MSO, or 0.25% (v/v) of NIS. Control of this specie ranged from 25 to 40% at 12 DAT up to 75 to 89% at 56 DAT. No significant differences in efficacy were seen between any of the treatments, suggesting no positive benefit from the surfactants when Celsius was applied at these rates on this species. In all of these experiments, weed infestations were severe enough to make turf tolerance assessments non-feasible." |
