WARM-SEASON TURFGRASSES - ANNUAL BLUEGRASS (POA ANNUA) CONTROL PRIOR TO OVERSEEDING TURF WITH PERENNIAL RYEGRASS
Product Description: This product is a postemergence, systemic herbicide with limited soil residual activity. It provides postemergence control of many annual and perennial sedges, grass and broadleaf weeds on highly managed turf, sod farms and native grass sites. It is a selective herbicide that can be used over the top of many perennial warm-season turfgrasses. Refer to the appropriate sections of the label for approved turf species.
Use Sites: This product may be used for general weed control on highly managed turf, native grasses, landscaped areas and ornamental nurseries. This product may be applied to residential and commercial sites, including apartment complexes, athletic fields, cemeteries, golf course fairways, golf course roughs, golf course tees, and other golf course areas, hotel properties, nurseries, office complexes, parks, public areas, retail sites, storage facilities, school grounds, sod and turfgrass seed farms, and other highly managed turfgrass sites. This product is not for use on golf course putting greens.
When to Spray: Best results are obtained when target weeds are actively growing and not disturbed by mowing for at least 2 days before and 2 days after application.
Time to Symptoms: This product is absorbed by both the roots and the foliage of plants and rapidly inhibits the growth of susceptible weeds. Susceptible weed growth stops within 24 hours of treatment even though visual symptoms are slow to develop. Susceptible weeds usually show yellowing or browning within 2 to 3 weeks. Warm, moist conditions following application will accelerate herbicidal activity. Cold, dry conditions will delay herbicidal activity. Weeds stressed by drought are less susceptible to this product.
Rainfastness: Heavy rainfall or irrigation within 2 hours after application may wash this product off of the foliage and a repeat application may be required for adequate control.
Maximum Annual Use Rate: The combined total of all treatments must not exceed 2.66 ounces of this product per acre per year.
IMPORTANT : Avoid contact of this product with the roots or foliage of susceptible non-target vegetation as injury may occur. This includes areas where this product may be washed or moved into contact with roots of desirable vegetation.
Susceptible plants may be injured if seeded or transplanted into treated areas unless otherwise directed in the label.
