GENERAL INFORMATION
SEDGEHAMMER Turf Herbicide is a selective herbicide for post-emergence control of yellow nutsedge and listed broadleaf weeds in established lawns, ornamental turfgrass, landscaped areas and commercial ornamental production nurseries. SEDGEHAMMER Turf Herbicide may be applied to commercial and residential turf and on other non-crop sites including: airports, cemeteries, fallow areas, golf courses, landscaped areas, public recreation areas, residential property, roadsides, school grounds, sports fields, landscaped areas with established woody ornamentals, container and field nurseries fairgrounds, race tracks, tennis courts, campgrounds and rightsof-way.
Field sprayer application: DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE S572.1) medium classification. Boom height must be 60 cm or less above the crop or ground.
DO NOT apply by air.

Buffer zones:
Use of the following spray methods or equipment DO NOT require a buffer zone: hand-held or backpack sprayer and spot treatment.
For application to rights-of-way, buffer zones for protection of sensitive terrestrial habitats are not required; however, the best available application strategies which minimize off-site drift, including meteorological conditions (e.g., wind direction, low wind speed) and spray equipment (e.g., coarse droplet sizes, minimizing height above canopy), should be used. Applicators must, however, observe the specified buffer zones for protection of sensitive aquatic habitats.
The buffer zones specified in the table below are required between the point of direct application and the closest downwind edge of sensitive terrestrial habitats (such as grasslands, forested areas, shelter belts, woodlots, hedgerows, riparian areas and shrublands) and sensitive freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs and wetlands).

For tank mixes, consult the labels of the tank-mix partners and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture and apply using the coarsest spray (ASAE) category indicated on the labels for those tank mix partners.
The spray drift buffer zones for this product can be modified based on weather conditions and spray equipment configuration by accessing the Buffer Zone Calculator on the Pest Management Regulatory Agency web site.
As this product is not registered for the control of pests in aquatic systems, DO NOT use to control aquatic pests.
DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.

MIXING INSTRUCTIONS
Fill the spray tank to about three-fourths of the desired volume and begin agitation. Add the recommended amount of SEDGEHAMMER Turf Herbicide. Complete the filling process while maintaining agitation. Remove the hose from the mixing tank immediately after filling to avoid siphoning back into the carrier source. Add nonionic surfactant and other adjuvants as the last ingredients in the tank. Spray solutions should be applied within 24 hours after mixing.

ADJUVANTS
Unless otherwise stated, nonionic surfactants (NIS) or crop oil concentrates (COC) are the only type of surfactants recommended for SEDGEHAMMER Turf Herbicide applications. Use of SEDGEHAMMER Turf
Herbicide without an adjuvant when weeds are present may result in reduced efficacy. DO NOT use both NIS and COC in the spray mixture. Use ONLY the lowest labeled rate of nonionic-type surfactants that contain at least 80% active ingredients. Crop oil concentrates may be used with SEDGEHAMMER Herbicide instead of nonionic surfactants.
