If you are seeing some wider bladed grasses at this time of year, it is not crabgrass. Crabgrass is an annual grass. It dies in the fall and comes up from seed in the late spring. It usually is not visible until the end of June. So what you are seeing now is definitely not crabgrass.
Quack grass is another wide bladed grass. It however is a perennial grass and will be starting to grow this early.
Crabgrass is normally treated by putting on products that reduce its germination from seed.
Because quack grass is already alive and growing, putting on something to reduce germination rarely of benefit.
