“…Native C 3 grasses, such as Stipa capillata and S. eriocaulis, from dry alpine grassland in the Austrian Alps (Larcher et al 1989) and Agropyron dasystachum from the Canadian prairie (Kowalenko & Romo 1998) were resistant to -36°C. C 4 grasses (e.g., Cynodon dactylon, Papasalum dilatatum, Setraria sphacelata) were readily killed by frosts of -3°C to -4°C in the New Zealand winter (Davies & Forde 1991). However, perennating structures of Canadian C 4 grasses were resistant to temperatures as low as -35°C in Distichlis stricta and Boutelia gracilis, -29°C in Spartina gracilis, and -27°C in Andropogon scoparius (Schwarz & Reaney 1989).…”

The frost resistance of tillers of Chionochloa rigida was measured at various dates and locations from late winter (August 2004) to early summer (December 2004). Frost resistance changed in accord with season, geographic location, and position on the tiller and was strongly related to estimated minimum temperatures at the date and site of collection. Foliar frost resistance was -21°C in late winter and -10°C in summer; leaf sheaths and bases were less frost resistance than laminas. The strong dependence on temperature suggests that the frost resistance of C. rigida would adjust to prevailing temperatures during a period of global warming, although it might render C. rigida more susceptible to episodic frosts. On a global scale, C. rigida is less frost resistant than many temperate pasture grasses and cereals and shows some affinity with tropical alpine vegetation.

“…Furthermore, dallisgrass exhibits tolerance of close mowing and can persist at mowing heights typical of golf course fairways (1.3 cm) and roughs (7.6 cm) (Henry et al 2007). Finally, dallisgrass continues active growth later into fall months than other warm-season perennial grasses (Davies and Forde 1991), further complicating its control.…”

Dallisgrass response to various MSMA and foramsulfuron herbicide combinations was evaluated from 2004 through 2006 in North Carolina. Dallisgrass control declined with herbicide rates; therefore, only the highest rates (foramsulfuron, 0.15 kg ai/ha; MSMA, 2.5 kg ai/ha) are discussed. Foramsulfuron followed by (fb) foramsulfuron 1 wk after initial treatment (WAIT) provided 60% control of dallisgrass 1 mo after initial treatment (MAIT), but control declined to 40% 3 MAIT. MSMA (2.5 kg ai/ha) applied three times provided 89% dallisgrass control 1 MAIT, but control declined to 71% 3 MAIT. Among 22 MSMA and foramsulfuron sequential application programs, MSMA fb foramsulfuron 2 WAIT fb MSMA 3 WAIT provided the highest control (94%) of dallisgrass 1 MAIT, and control levels remained high (93%) 3 MAIT. This herbicide program provided 85% control 1 yr after initial treatment (YAIT), whereas no other treatment provided greater than 37% control 1 YAIT. Timing of foramsulfuron application following the initial MSMA application affected the control of dallisgrass. Waiting 2 WAIT, rather than 1 WAIT, before applying foramsulfuron increased control of dallisgrass by 20% 1 MAIT and 19% 3 MAIT. However, the increase in control 1 YAIT was only 5% regardless of herbicide rate. The addition of a second application of MSMA following the application of foramsulfuron 2 WAIT of MSMA further increased control by 10% 1 MAIT, 37% 3 MAIT, and 48% 1 YAIT. Results from this study suggest dallisgrass may be controlled with applications of MSMA fb foramsulfuron 2 WAIT fb MSMA 3 WAIT applied during early to midsummer. The use of MSMA was required to achieve dallisgrass control, however, the relatively high level of control achieved 1 YAIT with a program including sequential applications of MSMA and foramsulfuron may help reduce the total amount of arsenical herbicides used to control dallisgrass infestations over time.

“…It responds well to fertilization with N up to 134 kg/ha, and optimally to P and K based on soil test. Furthermore, dallisgrass tolerates frequent defoliation better and maintains its forage quality longer into the growing season than many other commonly utilized perennial C 4 grasses [5,6].…”

Dallisgrass (Paspalum dilatatum) is well adapted to the Black Belt region of the southeastern US, and information on its productivity and nutritive quality as influenced by fertility is needed. In each yr of a 2-yr study, an existing dallisgrass pasture that had been subdivided into 48 plots of 9.3 m 2 each was fertilized with the equivalent of 34 (34N), 67 (67N), 101 (101N) or 134 (134N) kg N/ha from poultry litter (PL) or commercial fertilizer (CF; NH 4 NO 3). In both years, primarygrowth and vegetative regrowth forage was harvested in mid-August and late September, respectively, and forage from each harvest was clipped to either a 5-or 10-cm stubble height. Forage cut to a 5-cm height yielded 71% more (P < 0.001) DM than forage cut to a 10-cm height, but forage dry matter (DM) yields were not different between CF and PL treatments across years and fertilization rates. Concentration of crude protein (CP) was greater (P = 0.002) for CF than PL forage and increased for both fertilizer sources with increasing rates of N application. Forage concentrations of cell-wall constituents were not different between CF and PL treatments. Forage amended with CF had a higher concentration of Ca, Mg and Mn than PL-amended forage; however, forage amended with PL had a higher concentration of P and K than CF-amended forage. There was no effect of fertilizer source on forage concentration of Al, Cu or Zn. Results indicate that PL and CF were comparable for supporting productivity and nutritive quality of dallisgrass on Black Belt soils.
