Quackgrass is also commonly known as which of the following?

• A. Crouchgrass
• B. Goosegrass
• C. Bermuda Grass
• D. St. Augustine

Answer: (A)

Quackgrass is most commonly known as couch grass, a name turf professionals use for this persistent perennial weed that spreads via creeping underground rhizomes. This term fits because couch grass captures the plant’s growth habit and its long-lived, mat-forming spread, which is a key trait managers watch for in cool-season lawns. The other grasses listed are different species: goosegrass is a separate weed, Bermuda grass is a warm-season turf grass, and St. Augustine is another warm-season turf grass. So the best match for quackgrass’s common name is couch grass, with couchgrass often appearing as the variant spelling in some references.
