Hi-Yield Triclopyr Ester is a unique herbicide in that it kills many broadleaf weeds and suppresses Bermudagrass in a cool season lawn (tall/turf fescue, Kentucky bluegrass, and ryegrass). This is a great tool to stay ahead of Bermuda as it creeps into your fescue. Triclopyr Ester also controls actively growing annual and perennial broadleaf weeds including wild violet, clover, ground ivy, oxalis, and field bindweed. Not for use on warm-season lawns (zoysia, bermuda, and buffalo grass). Mix 3/8 to 3/4 fluid ounces of Hi-Yield Triclopyr Ester per 1000 square feet in enough water to provide uniform coverage of the target area. Apply at any time broadleaf weeds are susceptible. Always read and follow label instructions. 8 fl. oz. concentrate.
