Plant Growth Regulator. The active ingredient in Trimmit ® 2SC, 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.
Suppresses Poa annua (annual bluegrass) populations in perennial turfgrasses. Additionally, Cutless is the leading turf PGR for Poa annua suppression. Cutless selectively suppresses the growth of annual bluegrass to a greater degree than desirable perennial turfgrasses, such as creeping bentgrass, shifting the competitive growth advantage away.
The Type II PGR’s paclobutrazol and flurprimidol have been shown to be the most effective in reducing annual bluegrass populations over a period of time.
