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.
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.
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.
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.
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 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 is a great product labeled to treat Purple Nutsedge, Yellow Nutsedge, Kyllinga in most warm and cool season turfgrasses. Please see product label for complete list of tolerent turfgrasses.
Products that contain the active ingredient, Halosulfuron, are labeled for established turf species only. Dichondra is a ground cover that is not listed on any of the product labels as tolerable.
SedgeHammer Herbicide will kill yellow and purple nutsedge but not globe sedge. To control all 3 you would need to use something like the Dismiss Turf.
After treating with SedgeHammer+ Herbicide it will take time to completely kill the treated sedge but because the dead sedge will eventually decompose, there is no need to pull out the dead weeds.
The shelf life of SedgeHammer Herbicide is about 5-7 years. We recommend to keep it stored in a cool, dry place, out of extreme temperatures.
SedgeHammer Herbicide should not be applied as an over the top spray to desirable around groundcovers, ornamentals, vegetables, shrubs, trees, or flowers. Our best recommendation is to spot treat with a glyphosate product like Roundup QuikPro, taking care to not spray desirables.
