SedgeHammer + Turf Herbicide (13.5 gram pack ) Nutsedge Killer – Halosulfuron 5%

SedgeHammer Turf  Herbicide 13.5 gram pack ( 1 pack )
0.5 oz. (13.5 grams) in 1 to 2 gallons of water per 1,000 sq. ft.
Sedgehammer in the 13.5 gram pack already contains surfactant.
Halosulfuron-methyl – 5%
Controls yellow and purple nutsedge and certain tough broadleaf weeds like horsetail.
Also suppresses green kyllinga.
Low use rate (1 1/3 oz/Acre or less) or .9 grams per 1000 square feet.
Controls nutsedge by moving through the plant and affecting the underground growing points (rhizomes and tubers).
It controls nutsedge after emergence in cool and warm season
turfgrass (including St. Augustinegrass, Bermudagrass, Kentucky
bluegrass, tall and fine fescue, and perennial ryegrass)
Considered as one of the more “gentle to turfgrass” products.
Pets and people can return to treated area once spray dries.
How To Use NEW Sedgehammer+ Formula
Open packet and pour into 1 gallon of water.
Swirl or mix the solution thoroughly. One packet will cover 1,000 sq ft.
DO NOT add any non-ionic surfactant – it is already included in the packet for easy mixing.
While spraying, periodically swirl or shake the mixture to keep the product evenly distributed in the water.
Do not store the mixed solution as it will degrade and become ineffective.
For optimum results it is best to apply SedgeHammer to young, actively
growing nutsedge plants (plants that have emerged within the last 6
weeks). SedgeHammer works by killing the foliage and underground tubers.
However, nutsedge plants that survive longer than 6 weeks can produce
new nutlets. There may also be nutsedge that has emerged and sprouted
above ground since the time of your application. SedgeHammer
applications must be made consistently to ensure eventual eradication.
Read the label for specific directions regarding maximum number of
applications and rates.
Sedgehammer is absorbed into the leaf tissue within 24-48 hours and
enters the vascular system. It travels to the base of the leaves where
the growing point is located. Critical amino acid production within the
plant is then halted. Yellowing and browning of leaves usually occurs
within 10-14 days. It may take an additional 2 weeks before the nutsedge
dies. If the nutsedge is not actively growing or is stressed in any
way, this process may be delayed or interrupted.
How SedgeHammer Herbicide Works
SedgeHammer is a water-soluble granule formulation that is mixed with water and applied to target plants with a sprayer. SedgeHammer is a member of the sulfonylurea family, an ALS (acetolactate) enzyme inhibiting herbicide. The active ingredient is absorbed into leaf tissue as quickly as 24 to 48 hours after application, then translocated through the plant’s vascular system. The herbicide quickly inhibits amino acids, halting cell division and plant growth in both roots and shoots, causing eventual death in target plants.
A nonionic surfactant is an additive that aids the penetration of SedgeHammer into the plant tissue.
Surfactants are not only used in horticulture but are commonly used in many cleaning products. Their properties enable the herbicide to “sheet” or spread across the surface of a plant or weed. It is always recommended that a surfactant be used to help SedgeHammer penetrate the waxy layer of the nutsedge leaf. The surfactant also aids in dispersing the water droplets evenly across the leaf tissues and facilitates adsorption into the vascular system of the plant.

Target Uses of SedgeHammer
SedgeHammer Herbicide is a selective, post-emergent herbicide concentrate designed specifically to kill nutsedge and other broadleaf weeds without injury to turfgrasses, established ornamentals, shrubs, or trees. SedgeHammer can be used in both warm-season and cool-season turfgrasses, landscaped areas, and other non-crop areas.
SedgeHammer will not prevent germination of most labeled target weeds. Rather, it should be applied to actively growing weeds. If turfgrass or nutsedge is under stress, poor control may result. Also, desirable turfgrass, ornamentals, and trees should be well established before application. Do not apply to edible plants or gardens.
*Note that weeds can develop resistance to herbicides.
To minimize the potential for resistance development and/or to control resistant weed biotypes, use a variety of cultural, mechanical, and chemical weed control tactics. Rotate with herbicides having other modes of action.
ACTIVE INGREDIENT:
13.5 g package – Halosulfuron-methyl 5%
SedgeHammer Application Instructions
SedgeHammer is a powder concentrate to be diluted with water and applied with a pump sprayer. SedgeHammer should not be applied with hose-end sprayers since they are far less accurate than hand pump sprayers. When applying, spray the weeds thoroughly and wet the entire leaf surface of the undesirable plants. For best results, spray nutsedge after it has reached the 3 to 8 leaf stage of growth.
SedgeHammer often works with one application, but depending on the size and age of the nutsedge a second treatment may be required 6 to 10 weeks after the initial treatment. See “Other Tips” below for more information.
For best results, add a surfactant that is specifically made for horticultural purposes and labeled for use with an herbicide. Use only surfactants that contain at least 80 percent active material. Do not exceed the recommended amount of surfactant due to potential turf injury at higher rates.
*While spraying, periodically swirl or shake the mixture to keep the product evenly distributed in the water.
*Do not store the mixed solution as it will degrade and become ineffective.
The 13.5 gram packets already contain a surfactant, so you only need to mix the contents of the packet itself with a gallon of water. See below for further details. Always read the product label completely before use.
Each 13.5 g packet makes 1 gallon of finished solution and already contains a surfactant. Each gallon of finished solution covers approximately 1,000 square feet.
Standard Application Dilution rates / Mixing Ratios for SedgeHammer:
*13.5 g packet – Entire contents of 1 packet (0.5 oz.) per gallon of water – Ideal for spot treatments

Extra Tips for Using SedgeHammer
For best results, do not mow turf for 2 days before or 2 days after application.
SedgeHammer is effective if no rainfall occurs within 3 hours, but best results are obtained with no rainfall or irrigation for at least 4 hours.
Use only in established turfgrass:
allow turf to develop a good root system and uniform stand before application.
Results may take 5-7 days to begin to appear.
Do not apply when turfgrass or nutsedge is under stress.
Do not apply when temperatures exceed 85 degrees F.
Do not apply to golf course putting greens.
For transplanted woody ornamentals, allow 3 months after transplanting before applying this product.
When using in fallow areas, allow 4 weeks between application and transplanting of woody ornamentals or seeding or sodding of turfgrass.
SedgeHammer may remain active in the soil up to 3 years after application.
Store concentrate under cool, dry conditions.
