TURF TYPE TALL FESCUE
PROGRASS SC Herbicide is a suspension concentrate containing 4 lbs. active ingredient per U.S. gallon for use on established perennial ryegrass, Kentucky bluegrass, creeping bentgrass, turf-type tall fescue, St. Augustinegrass, and dormant bermudagrass for the control and/or suppression of specific annual grasses and broadleaf weeds. It may also be used, as directed, after overseeding specific grasses.
PROGRASS SC is intended for professional use only on the ornamental turf of sites such as golf courses, sod farms, parks, cemeteries, lawns of commercial establishments and homeowner lawns (see Use Precautions below).
PROGRASS SC has both preemergent and early (two-leaf stage) postemergent activity; it is used most effectively in programs emphasizing both approaches.
- PROGRASS SC should be used only for recommended purposes and at the recommended rates (DO NOT OVERAPPLY).
- Avoid spray overlap or turf injury may occur.
- Use of a spray colorant or indicator in the spray tank is recommended so that spray pattern overlapping can be avoided.
- Do not apply with flood jet nozzles and hand-held sprayers, since treatments may not be uniform.
- Do not apply this product through any type of irrigation system.
- PROGRASS SC application is most effective on healthy, vigorously growing turf.
- PROGRASS SC may be applied to homeowner lawns by licensed or certified applicators. PROGRASS SC is not intended for use by home-owners.
- Overseeding is recommended in conjunction with PROGRASS SC applications to achieve conversion to desired turfgrass species and to avoid stand thinning due to annual bluegrass loss.
- When overseeding, use the rate of PROGRASS SC recommended for the overseeded species. In mixed stands of established turfgrasses, use the rate recommended for the least tolerant species.
- Do not apply PROGRASS SC within 8 weeks following the application of a Plant Growth Regulator. A PROGRASS SC program may be initiated on creeping bentgrass 3 weeks after a single application of PRIMO has been applied.
- PROGRASS SC application is recommended for golf course fairways, roughs, and tees but at fairway-height only. Do not apply to putting greens.
- Do not apply PROGRASS SC to zoysiagrass and hard or fine fescue; serious injury may result.
SPRAY EQUIPMENT, APPLICATION, AND PRECAUTIONS
Apply PROGRASS SC Herbicide using standard, low pressure (20 to 50 psi) spray equipment. Spray equipment should be carefully calibrated before use and checked frequently during application. Addition of a spray indicator may improve treatment uniformity. The tank and line should be cleaned and rinsed before and after using PROGRASS SC. Do not allow spray mixture to stand in tank overnight. Store unused spray mixture in tightly-sealed containers and protect from frost.
The following turfgrass cultivars have shown tolerance to PROGRASS SC Herbicide; however, all species and varieties have not been tested. PROGRASS SC has been used safely on the following turfgrass cultivars, but its use is not strictly limited to these. Before large scale use of PROGRASS SC on other cultivars, a tolerance test on a small area is recommended.
PERENNIAL RYEGRASS—Acclaim, Blazer, Dasker, Derby, Elka, Fiesta, Goalie, Hunter, Linn, Loretta, Manhattan II, Palmer, Pennfine, Regal, Yorktown
KENTUCKY BLUEGRASS—Adelphi, American, Aspen, Asset, Challenger, Classic, Emundi, Huntsville, Georgetown, Glade, Haga, Julic, Liberty, Merit, Midnight, Monopoly, Mystic, Parade, Rugby, Sydsport, Touchdown.
DO NOT APPLY to the following cultivars: Northstar, Explorer, Limousine, RAN I and Total Eclipse.
CREEPING BENTGRASS—Carmen, Cobra, Highland, Lopez, Mariner, National, Penncross, Providence, Putter, Southshore, SR1020, and Viper have shown good to excellent tolerance to PROGRASS SC Herbicide. Injury has been noted on Emerald, Penneagle, and Pennlinks occasionally. PROGRASS SC may cause serious injury to Cohansey, Colonial, South German varieties, Egmont, Bardot, Tracenta, Allure, Astoria, and SR 7100.
TURF-TYPE TALL FESCUE—America, Arid, Mustang
ST. AUGUSTINEGRASS—Raleigh DORMANT BERMUDAGRASS—Tifgreen, Tidwarf. Common bermudagrass is more susceptible to PROGRASS injury than hybrid bermudagrass.
Fall applications to turfgrass sites to control annual bluegrass are most effective if application is initiated during the period of maximum weed germination and ended as close to the first killing freeze as possible. Spring applications may be made during the period of maximum weed germination. Consult the university extension service or weed science specialist for these dates in your locality. Spring applications are most effective following fall applications.

TURF TYPE TALL FESCUE
Apply PROGRASS SC Herbicide to turf-type tall fescue in the fall. If overseeding with turf-type tall fescue, PROGRASS SC application and the seeding may be simultaneous.
Recommended rates and timing: Refer to label text for further instructions regarding each grass species.
Application Rate: Apply recommended rate of PROGRASS SC in 20 to 60 gallons of water per acre or 1 to 3 gallons of water per 1000 Ft2.
Overseeding Safety Interval: Interval applies to overseeding specific grass on same type of grass after last PROGRASS SC treatment.
Application Safety Interval: Refers to interval in which PROGRASS SC may be safely applied to specific grass following seed emergence.
Number of Applications: 2-3
Application Interval: 21 – 28 days
Application Safety Interval (Weeks After Emergence): 2-3
