Musketeer is the first turf plant growth regulator (PGR) to incorporate three PGR technologies. Musketeer is a patented formulation combining the optimal ratios of flurprimidol, paclobutrazol and trinexapac-ethyl which results in aggressive suppression of Poa annua, more uniform growth suppression, improved turfgrass color and quality, and extended spray intervals.

Growth regulation from Musketeer results from suppression of the plant hormone, gibberellic acid (GA), responsible for cell elongation in most plants. Musketeer has multi-site activity. It inhibits GA production early and late in the GA biosynthesis pathway resulting in more efficient GA regulation. Musketeer is absorbed by plants via roots, stems and leaves providing for more effective uptake.
