Per the product label, St. Augustinegrass, Bermudagrass, Centipedegrass, and Zoysiagrass species can experience yellowing after application of Princep Liquid Herbicide under certain circumstances. The product label suggests the following reasons to help avoid turf injury: (1) Use only on turfgrass reasonably free of infestations of insects, nematodes, and diseases. (2) Do not use north of NC (except in the VA Coastal Plains) or on soils with a pH above 7.8. (3) Do not use on muck or alkaline soils. (4) Do not apply over the rooting area of trees or ornamentals not listed on this label. (5) Do not seed or overseed with desirable turfgrass within 4 months before or 6 months after treatment. (6) Do not apply this product to newly seeded grasses until they have overwintered and have a well-developed rhizome system. (7) Do not exceed 2 qt/A of Princep Liquid within 12 months of seeding grasses.
