Yes, SedgeHammer Herbicide is mixed at 1 pack (13.5 gram) per gallon of water per 1,000 sq ft on established turf species listed on the product label with any hand pump or backpack sprayer.
No, SedgeHammer Herbicide will not kill Bahiagrass in St. Augustine. It can safely be applied to both turf types. You could use a product like Image Kills Nutsedge Concentrate. It can be used in established St. Augustine turf to kill Bahiagrass.
Per the product label, you need to allow 4 weeks between an application of SedgeHammer Herbicide and seeding. Treated areas may be overseeded with annual or perennial ryegrass or bermudagrass 2 weeks after application.
Best results are obtained with no rainfall or irrigation for at least 4 hours after an application of SedgeHammer Herbicide, but we recommend waiting at least 24 hours.
SedgeHammer Herbicide is a great choice for purple nutsedge, yellow nutsedge and kyllinga. Please refer to the product label to be sure it is safe to apply to your turfgrass.
We always recommend doing a sample tank mix first when mixing with other products to make sure that everything mixes well. SedgeHammer Herbicide is mixed at the rate of 0.5 to 1.0 oz (1-2 packets) per gallon of water as directed on the product label.
Yes, Sedgehammer Herbicide works systemically slowly through the plant and all the way down to the nutlets in nutsedge.
Yes, fertilizer can be applied at the same time as SedgeHammer Herbicide. There is no wait time.
Tenacity is labeled to control yellow nutsedge only, so it could be you are treating purple nutsedge, or kyllinga, which is in the same family and looks similar to sedges. If you have applied the Tenacity to the sedge with a surfactant and it has not died out completely and is only white after 5 weeks we would suggest to go ahead and try the Sedgehammer on any new growth. Sedge control products are supposed to be very slow killing so that it can try to move through the whole plant and roots as much as possible. Sedgehammer can take at least 3-5 weeks to kill down to the root and can be reapplied after 6 weeks if a second application is needed.
SedgeHammer Herbicide is only labeled to control kylinga, yellow, purple nutsedge and a small number of other weeds but it’s not labeled for clover.
SedgeHammer Herbicide is mixed at 13.5 grams in 1 gallon of water to cover 1000 sq. ft. No additional watering is required.
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.
For better results, we advise that you apply SedgeHammer Herbicide to a dry lawn at least 24 hours before you are expecting any rain.
Yes, per the label instructions you will mix 1 gallon of water with each 13.5 gram packet of SedgeHammer Herbicide.
SedgeHammer Herbicide is only labeled for turf and ornamental applications. It cannot be used in a pasture.Unfortunately, we apologize but do not have a product that would kill the sedge and also be safe for pasture areas. We would recommend contacting your local agricultural department for a recommendation.
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.
Once SedgeHammer has been mixed with water, it should be used or discarded within 24 hours of dilution.
Sedgehammer is labeled to kill nutsedge without injury to listed established turfgrasses. You should not apply over-the-top of desirable ornamentals, shrubs, and/or trees. We are not sure how the product would effect prairie so we recommend calling the manufacturer who is the expert on their own product. The manufacturer is Gowan Company and they can be reached at (928) 783-8844.
