| Abstract/Contents: | "Seashore paspalum (Paspalum vaginatum) is a perennial warm season turfgrass native to the tropical and subtropical regions of North and South America. It has been around for thousands of years, but has only been used commercially for the past decade. The plant spreads by rhizomes and stolons that root at the nodes to form a deep fibrous root system. The texture is slightly coarser than bermudagrass unless mowed at less than an inch. Seashore paspalum thrives in moist soils and has a high tolerance to salinity. Experiments were conducted under greenhouse condition at the University of Florida, Milton Campus during the summer of 2003. In the first study, eight weeds were tested for salinity tolerance: torpedograss, dollarweed, Virginia buttonweed, large crabgrass, common bermudagrass, purple nutsedge, goosegrass, and Florida pusley. The weeds were transplanted into six-inch pots and placed in the greenhouse. Each weed species was treated with five saltwater treatments which were as follows: 34,000 ppm (1x), 25,500 ppm (3/4x), 17,000 ppm (1/2x), 8,500 ppm (1/4x), and untreated (0x). In the second study, Seashore paspalum plugs were transplanted into six-inch pots, and watered with five saltwater treatments (same concentrations as for the weed tolerance study). Eighteen different herbicides were then applied to each saltwater treatment. Visual ratings and dry weights were collected for the weeds. Weeds that showed injury levels of greater than 70% were: Purple nutsedge and bermudagrass (1x), crabgrass and dollarweed (3/4x and 1x), goosegrass (1/2x, 3/4x, and 1x), Virginia buttonweed and Florida pusley (all rates). Torpedograss showed injury less than 20% at the highest rate. Although visual injury was noted for many of the weeds, no significant dry weight loss was found except for crabgrass at the 1x rate. Visual ratings based on the untreated check were taken for the herbicide/saltwater treatments on the Seashore paspalum. There was a significant effect of herbicide and salt concentration but no salt by herbicide interaction. All herbicides showed significant difference compared to the untreated control, with atrazine, bromoxynil, metribuzin, Trimec Southern, imazaquin, and bentazon showing greater than 80% reduction in turf quality. Salt concentrations greater than 0.75X resulted in significant loss of quality when averaged for all herbicide treatments." |
