| Abstract/Contents: | "Several golf courses are beginning to use native grass species for deep roughs and ornamental beds. Many of these native grass species are not as competitive as the weeds that are present. Broomsedge (Andropogon virginicus) and lovegrass (Eragrostis spp.) are two of these native grass species. Smooth crabgrass (Digitaria ischaemum) and ragweed (Ambrosia spp.) are two weeds that are problems in these plantings. In an effort to control these weeds and give the native grass species an advantage, herbicides need to be tested for efficacy and tolerance. Field trials were conducted in 2001 evaluating different rates of Plateau (imazapic) and single rates of Confont (triclopyr + clopyralid), Trimec Classic (2,4-D + MCPP + dicamba), and Image (imazaquin). Plateau and Image treatments had a nonionic surfactant (X77) added at a rate of 0.25%v/v. Broomsedge was treated with Plateau (2 to 12 oz/a), Confront (1 pt/a), Trimec Classic (3.5 pt/a), and Image (0.5 lb ai/a). Lovegrass was treated with Plateau (2 to 6 oz/a), Confront (1 pt/a), Trimec Classic (3.5 pt/a), and Image (0.5 lb ai/a). Neither broomsedge nor lovegrass showed a significant reduction in quality when comparing the treatments to the nontreated. Smooth crabgrass and ragweed were treated with Plateau (2 to 12 oz/a), Confront (1 pt/a), Trimec Classic (3.5 pt/a), and Image (0.5 lb ai/a). At 11 weeks after treatment, Plateau at 6, 8, 10, and 12 oz/a provided greater than 85% control of smooth crabgrass. At 11 weeks after treatment, Plateau at 10 and 12 oz/a, Confront and Trimec Classic provided greater than 90% control of ragweed." |
