Hi-Yield Triclopyr Ester should be used only on well-established turfgrasses. This is usually after at least 4 weeks or the second mowing, whichever is longer. Per the product label: While established grasses are tolerant to this product, newly seeded grasses may be injured until well established (as indicated by vigorous growth, tillering and the development of a secondary root system). Do not reseed treated areas for a minimum of three weeks after treatment.
