| Abstract/Contents: | "Two experiments were conducted on Mississippi highway rights-of-way to evaluate tolerance of common bermudagrass [Cynodon dactylon (L.) Pers.] to Roundup(R) (glyphosate), Campaign(R) (glyphosate + 2, 4-D), Oust(R) (sulfometuron), Dacamine(R) (2, 4-D amine), Daconate(R) (MSMA) + Dacamine(R), and Roundup(R), and Roundup(R) + Escort(R) (metsulfuron). One experiment was designed as a factorial using location (Oktibbeha, Grenada, and Noxubee Counties), application time [5% (March) and 50% (April) growth resumption following dormancy], and herbicides as factors. Treatments were: Campaign(R) (32, 48, 64, or 128 oz product/A), Oust(R) (0.25, 0.5, 1.0, or 2.0 oz product/A), and Dacamine(R) (32 or 64 oz product/A). Bermudagrass density was evaluated at 2, 4, 6, and 8 wk after 50% resumption of growth. When averaged across locations (2 wk after 50% resumption of growth), greater than or equal to 1.0 oz/A Oust(R) applied in March resulted in less density compared to applications of the same rates in April. April applications of 32, 48, or 128 oz/A of Campaign(R) resulted in less density compared to applications of the same rates applied in March. At 4 wk after 50% resumption of growth, all rates of Oust(R) caused a reduction in bermudagrass density when applied in April at Grenada County. Bermudagrass density was reduced with greater than or equal to 0.5 oz/A Oust(R) applied in April when rated 4 wk after 50% resumption of growth. Applying 32 and 128 oz/A of Campaign(R) in April at the Noxubee County location resulted in less density when rated 4 wk after 50% resumption of growth. The second experiment was conducted in Winston and Grenada Counties. Roundup(R) (16 or 24 oz product/A), Campaign(R) (32 or 48 oz/A), Roundup(R) + Escort(R) (16 + 0.5 oz product/A), Daconate(R) (43 or 64 oz product/A), Dacamine(R) (32 or 64 oz/A), and Daconate(R) + Dacamine(R) (43 + 32 oz/A or 64 + 32 oz/A) were applied at 100% resumption of bermudagrass growth following dormancy (July). The design was a split plot with locations as the main plots and herbicides as the sub-plots. At Winston County, significant bermudagrass injury was observed following all treatments containing Roundup(R) or Campaign(R) through 4 wk after treatment (WAT). With 16 or 24 oz/A Roundup(R) or 16 + 0.5 oz/A Roundup(R) + Escort(R), injury was observed at 4 and 8 WAT (greater than or equal to 30% and greater than or equal to 10%, respectively). At Grenada County, 16 or 24 oz/A Roundup(R) or 16 + 0.5 oz/A Roundup(R) + Escort(R) , resulted in injury through 6 WAT. Both rates of Campaign(R) resulted in injury 2 WAT." |
