| Abstract/Contents: | "Dallisgrass (Paspalum dilatatum) and bahiagrass (Paspalum notatum) are rhizomatous, perennial grass species that readily invade golf course fairways and roughs. These species are widely distributed throughout the state of North Carolina due to their tolerance of both droughty, sandy soils and moist, clayey soils. Currently, few post-emergent herbicide options exist for the effective, economical control of these weeds. Examination of their spatial distribution and population ecology may provide clues to improving management tactics. To date, studies of weed species distribution on golf courses have been limited by species identifications and low GPS resolution. The distribution of these species was evaluated in both golf course fairways and roughs. Golf courses were selected based on the presence of both weed species. Individual plants were mapped in the fairway and rough of several holes using a high precision (RTK) GPS unit. The RTK unit was also used to delineate between the rough and fairway height of cut as well as the elevation characteristics of each particular hole. Volumetric soil moisture content (theta probe) and soil penetration resistance (penetrometer) readings were taken on a 9-m grid. Characteristics used for initial correlation analysis consisted of mowing height, elevation, volumetric soil water content, and soil penetration resistance. Preliminary results indicate that dense patches of bahiagrass predominantly occur in the rough, while dallisgrass occurs at both mowing heights. Compaction data suggest that bahiagrass may be more tolerant to compacted soil than dallisgrass. The effect of volumetric soil moisture content is unclear at this time. Elevation is unlikely a factor affecting Paspalum distribution." |
