Sedgemaster Herbicide, manufactured by Quali-Pro, is a selective herbicide for both pre-emergent and post-emergent control and suppression of sedges and broadleaf weeds such as nutsedge in turf and other non-crop sites without injury to turfgrasses and ornamentals.

This easy to measure water dispensable granule offers flexibility, allowing users to apply it as a spot treatment to listed weeds or as a broadcast treatment to treat large scale areas such as acres. Once applied, its active ingredient halosulfuron-methyl 75% quickly eliminates weeds, resulting in stunting and eventual death within 7 to 14 days.

Although, Sedgemaster Herbicide is designed to eliminate nutsedge it can be used to effectively get rid of other broadleaf weeds in warm-seasoned turf and cool-seasoned turf, as well as landscape areas.

Tools Needed

Sedgemaster comes with a cup for convenient measuring. To apply, you will need either a handheld sprayer, backpack sprayer, hose end sprayer, or a spray rig for large volume applications.

How to Use

• Step 1: Determine how much product you will need by measuring the treatment area. Do this by measuring the length and width, and then multiplying them together (length x width = square feet). To find acreage, take your square footage and divide by 43,560. Mix rates will vary on the targeted weed and treatment area between 0.66 to 2.66 ounces of product per acre with 10 to 100 gallons of water. For spot treatments, mix 0.03 to 0.06 oz. of product with 1 to 2 gallons of water to treat 1,000 sq. ft.
• Step 2: To mix, fill your sprayer halfway with water, and the add the required amount of Sedgemaster based on your calculations. Fill your sprayer the rest of the way with water and shake to ensure and even mix.
• Step 3: Apply as either a broadcast or spot treatment over your area. Make an even application, spraying weeds to the point of wet not runoff with a low to medium pressure spray. Keep all people and pets off the treated area until dry. Follow up applications may be necessary for fully established weeds. 

Where to Use

Sedgemaster Herbicide can be used on warm and cool-season turfgrasses on established lawns, ornamental turfgrass, landscaped areas, commercial and residential turfgrass, and other non-crop sites including airports, cemeteries, fallow non-crop areas, golf courses, landscaped areas, public recreation areas, roadsides, school grounds, sod or turf seed farms, sports fields, landscaped areas with established woody ornamentals, fairgrounds, race tracks, tennis courts, campgrounds, and rights-of-way.

When to Use

For best results, apply Sedgemaster when weed are actively growing and not yet fully established. Apply on calm days when wind speeds are low to minimize drift and when rain is not in the immediate forecast for at least 4 hours.

Safety Information

Sedgemaster Herbicide is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when applying or mixing this product.

Special Considerations

A second application may need to sufficiently control of later germinated weeds when used for residual control of early post-emergent treatments.
