CAUTION: DO NOT attempt the glyphosate treatment described above on lawns or pastures. It isn't intended for high maintenance turf-sites of any type, and certainly NOT for St. Augustine or centipede grass - which are very susceptable to glyphosate. Common bermudagrass is the most tolerant specie, and then, only in "rough maintenance" areas.

FYI: there is a product called PRIMO which may be used on maintained turf to reduce growth and mowing frequency. PRIMO is a true plant growth-regulator (PGR) which shortens the internodes on most turfgrass species - producing a shorter, more compact growth profile while reducing the amount of clippings from mowings. It has a very low use-rate: .25 oz per 1,000 sq. ft.
