Clarelle PGR (1 gallon)

Clarelle Plant Growth Regulator slows grass growth and suppresses Poa. The active ingredient in Clarelle, Paclobutrazol, suppresses Poa annua and is a proven plant growth regulator for managing top growth of turfgrasses. Use it on established hybrid bermudagrass, bentgrass, bluegrass and perennial ryegrass fairways, tees, and roughs. For growth suppression on established bermudagrass and St. Augustine, it can be used when the grass is green, actively growing and has recovered from dormancy.
