SedgeHammer Herbicide should not be used on pastures or grazing areas, and you should not treat around hay that will be used for animal feed. The SedgeHammer should not affect Timothy grass that may be contacted by the herbicide, although the product label does not specify information about this plant, so we would recommend spot treating a small area first before applying over a large area with this plant. The 1.33 oz bottle of SedgeHammer will yield about 40 gallons of finished solution. You should add 2 teaspoons of a non-ionic surfactant per gallon of water when diluting SedgeHammer from the larger bottle. The smaller packets already have a surfactant mixed in with the product.
SedgeHammer Herbicide should not be applied within 2 days before or 2 days after mowing.
Per the manufacturer, you may need to wait a few months in order to plant as you may need to do multiple treatments of SedgeHammer Herbicide. If you do make multiple treatments, you can plant new perennials and annuals at least 4-6 weeks after your last application.
SedgeHammer Herbicide is labled to control only the broadleaf weeds listed on the label. However, since flowers are considered a broadleaf plant species as well, you would want to not spray over the top of the desireable plants. Try to limit sprays to only the weeds you wish to eliminate and be cautious of any drift of the product to nearby flowers.
If you have SedgeHammer Herbicide in the packets, you do not need to measure anything as the packets are pre-measured. If you have SedgeHammer in the 1.33 oz. bottle and have lost the spoon, we can contact the manufacturer to see if we can have a new spoon sent to you. Without the spoon you likely would need a scale that can measure in grams. If you would like us to try and send you the spoon just email us back with your address, or you can contact the manufacturer directly at 800-883-1844.
We recommend that you apply quinclorac separately from the small Sedgehammer packets since the Sedgehammer packet already contains a surfactant. Since quinclorac products generally require a more aggressive methylated seed oil surfactant, mixing these would cause extra stress on your desirable grass and may be too harsh.
We would not recommend tank mixing SedgeHammer Herbicide with something like Trimec as the Sedgehammer requires a surfactant to use and Trimec does not. Using one with Trimec could cause injury to your lawn since it already contains one and does not need any additional.
Sedgehammer should not be applied to any areas where there are desired ornamentals, flowers, shrubs etc. It should only be applied to turfgrass for nutsedge control.
SedgeHammer Herbicide is not labeled to be used in food plots and is not labeled to control clover. We currently do not have a product labeled to be used in food plots for clover. Most of the time you have to spot treat where the sedge is coming up with a glyphosate based product like the Glyphosel Pro being careful to spray as little of the clover as possible.
SedgeHammer Herbicide is only labeled for turf and ornamental applications. It cannot be used in a pasture with horses.
The Sedgehammer herbicide kills nutsedge without injury to listed established turfgrass. It should not be used around desirable ornamentals, shrubs, and/or trees or around or on any edible plants. Certain products are not labeled for use around edibles as it could cause harm to the plant either through absorbing it into the food you are going to eat, or by killing the plant. Unless it has an agricultural label you can not use it around edibles or near the drip line. If you want more details on how using SedgeHammer to close to edibles can affect them, you can contact the manufacturer Gowan at (800) 883-1844.
Because sedges are so hard to control there aren't many pre emergents on the market that will work on nutgrass/sedge at all. Freehand is one that works well and can be used in a variety of bedding and turf areas.
You can either spot treat with roundup or sedge control product like Sedgehammer for post emergent control over the nutgrass.
Sedgehammer Herbicide in the 13.5 gram pack is ideal for treating areas of 1,000 sq ft. or less. At this time we are only able to ship within the U.S.
Sedgehammer as well as any other product on the market needs to be used within 24-48 hours of mixing it up in your tank. Try to only mix up what you need at a time or see if there are other areas you can treat with the product for weed control to use all of what was mixed.
SedgeHammer Herbicide would be a good choice to control nutsedge in your lawn. Just be careful to apply outside of the drip lines of any fruit or nut trees.
The SedgeHammer Herbicide packs contain a surfactant to increase the effectiveness of the product. It is not necessary to apply it with another product for faster results. Please refer to the product label for complete mixing and application instructions.
SedgeHammer Herbicide is a post emergent herbicide which should only be used to control listed weeds during a time when they are actively growing. Most weeds are in an actively growing state when soil temperatures (not air) are a minimum of 65 degrees or higher consistently for a week or more.
