I want to use to kill creeping butter cups on perennial ryegrass lawn in Seattle area in October. Will this be effective and not harm perennial ryegrass? If so, what mixture is recommended per gallon of water?
Crossbow Herbicide is not labeled for use on home lawns so we cannot recommend it. We would recommend using Dismiss Turf instead which is labeled for use on perennial ryegrass to control/suppress buttercups.
