No, this is a selective herbicide designed specifically to target over 250 types of broadleaf weeds like dandelions, clover, and thistle. It will not kill your desirable lawn grasses when applied according to the label directions.

You will need to dilute the concentrate with water and apply it using a standard spray tank. Be sure to follow the dilution ratios provided on the label to ensure you are applying the correct concentration for your lawn size.
