Dallisgrass Treatment

Dallisgrass (Paspalum dilatatum) is a perennial, warm season grass that readily invades turf grass areas throughout Texas and the Southeastern states. Dallisgrass is native to South America and was introduced into the U.S. for its value as a forage plant. The grass was named for A.T. Dallis of LaGrange, Georgia, who was an enthusiastic proponent of the plant around 1900.


Dallisgrass grows in clumps, or bunches. Leaves are produced near the base of the plant on shoots that arise from a knotty base of very short rhizomes. Relative to turf grasses, especially Bermuda grass, the leaves of Dallisgrass are much coarser textured. Dallisgrass also produces unsightly seed stalks several feet above the turf. After mowing, Dallisgrass leaves elongate much faster than Bermuda grass turf and significantly increases the mowing needs for Bermuda grass turf areas.
