چکیده
• j ermudagrass is a popular turfgrass used on athletic fields • due to its aggressive summer growth habit, fine leaf texhue, and dark green color. However, if mowed infre• quently, excessive scalping and dipping production combine to decrease its aesthetic quality. Plant growth fl:'gulalors (PGRs) were introduced into the turf industry in the 1950's and since have been used in part to reduce mowing requirements and enhance color of bermudagrass. PGRs are classified as Type I or Type 11 based on their mode of action. Type I PGRs, maleic hydrazide, mef1uidide, and umidochlcr, for example, inhibit cell division. Since being introduced, their use has become limited due to high potential for phytotoxicity and reductions
