Problem: Dallisgrass (Lawns)
Paspalum dilatatum This warm-season grassy weed is one of the most troublesome in the southern United States. It begins growth in very early spring and prefers warm, moist areas and high-cut lawns. It forms distinct clumps. Once established in low-cut lawns, however, it spreads rapidly. It is a deep-rooted perennial plant that reproduces by seeds and underground stems.
After treated weeds have died, reseed the dead areas.
