If you over-apply Mec Amine D 3-Way Broadleaf Herbicide or any similar post-emergent herbicide, then you risk damaging your desirable turf. You may need to fertilize to help turf recover, or if there is irreparable damage, then you may need to reseed those areas the next season. We encourage you always to read and follow the product label instructions for any herbicides.
