A multiple application program using Musketeer provides: 1). Poa annua suppression and cool-season turf conversion, and 2). growth reduction of perennial turfgrass species resulting in decreased mowing frequency and turfgrass clippings. For cool-season grass, begin initial application in early spring following resumption of active growth. For warm-season grass, begin initial applications when the grass has completely recovered from winter dormancy and is growing vigorously. For both warm- and cool-season grass, discontinue applications a minimum of 4 weeks before the onset of inactive grass growth or winter dormancy.
Rates should be adjusted to fit the users targeted level of conversion, which is also based upon starting Poa annua population. Use the table below for rate recommendations on turf species.
1). Apply in early spring following resumption of active growth of the grass. Discontinue fall applications 4 weeks before the onset of inactive grass growth or winter dormancy.
2). For perennial ryegrass overseeded fairways, delay applications until perennial ryegrass is well established (4 weeks after germination).
