Q

I want to eliminate nutsedge. Can SedgeHammer Herbicide be applied to a new, Empire Zoysia sodded lawn?

Sedgehammer is great for the nutsedge, but it is not recommended to be used on a brand new lawn. The real question would be how "new" is your lawn? Sedgehammer should only be used once your "new" grass is established, usually after 2-3 months so the roots have time to…

Sedgehammer is great for the nutsedge, but it is not recommended to be used on a brand new lawn. The real question would be how "new" is your lawn? Sedgehammer should only be used once your "new" grass is established, usually after 2-3 months so the roots have time to really take root. If this is the case and your lawn is established, then SedgeHammer would be great to use. It is recommended that you use a surfactant with the SedgeHammer to help it stick to the nutsedge and be more effective. We recommend Dynamic to use with the Sedgehammer.

Sedgehammer is one of the most “gentle- to- turf” products around. It has proven to be safe to most commonly used grasses of North America and has been successfully used for many years. Many other products are safe to only warm season or certain kinds of turfgrass. Turf should be well established with a good root system prior to application. We recommend contacting your local cooperative extension office to enquire about specific plants when using SedgeHammer to be sure it will not cause damage.

Q

After I mix 2 gallons of Sedgehammer, how long will it remain effective?
I have my nutsedge down to a small area with only a dozen colonies so I mix 2 gallons and fill a one quart spray bottle for convenience. How long will the remaining liquid product remain effective?

A

Typically it is not recommended to leave any pesticide solution in a sprayer for more than two weeks at a time. You should only mix what you plan on using. If you want to leave the product in the sprayer for longer you should at least shake and agitate the sprayer every few days to keep …

Q

Can I use SedgeHammer to kill nutsedge right before sodding with St. Augustine?
I have bare soil (with nutsedge) right now and am planning to sod in the next 7-10 days. Or do I need to place the sod and then wait 4-6 weeks and go over it with the SedgeHammer?

A

Per the label on Sedgehammer, you are not supposed to reseed or sod within 3 to 4 weeks of using Sedgehammer. Therefore you have only a couple of options. One, is to treat the sedgehammer and stun it with a glyphosate (round up) type product which allows you to reseed within 7 days with …

Or, you can treat with Sedgehammer and wait 3 to 4 weeks before re sodding. If you must sod in 7 to 10 days, then you should treat the nutsedge with a glyphosate product and then you can treat with sedgehammer later if any new nutsedge makes it through the sod you are applying.

Q

I also have bare soil (with nutsedge) throughout. I plan to plant a lawn in about 8 months to a year.
Because I have no plants, I thought about using vegetation killer, but do not want to damage the soil. What are my options? This stuff is spreading fast!

A

If you only have bare soil with sedge growing from it, then you should just use a glyphosate product which will kill anything it touches basically. Sedgehammer is great for sedge, but is meant for use when nutsedge is in grass that you don't want to kill. A professional glyphosate will k…

If you only have bare soil with sedge growing from it, then you should just use a glyphosate product which will kill anything it touches basically. Sedgehammer is great for sedge, but is meant for use when nutsedge is in grass that you don't want to kill. A professional glyphosate will kill the nutsedge much quicker. Also it does not stay in the soil that long, so you can re-seed just weeks after application. Vegetation killers and soil sterilants are meant to not let anything grow in that area for a long time. So if you plan on seeding eventually then you should not use a vegetation killer product.

Q

What surfactant should I use with the Sedgehammer Herbicide?
Is there a preference as to which type? I noticed there are varying types, Non-Ionic, DyneAmic. Please advise as I plan to purchase ASAP. Thanks

A

All the surfactants on our website are non-ionic which is the type of surfactant the manufacturer of SedgeHammer herbicide recommends for use with their product in the bottle size (1.33 oz). The 13.5 gram pack of SedgeHammer already includes a built-in surfactant.

Q

I have a large lawn - about 50,000 square feet. Can SedgeHammer Herbicide be used on a hose end sprayer and, if so, how?

A

A hose end sprayer would not be the best applicator for a water dispersible granule like Sedgehammer. It is important to make sure the correct amount of product goes over a specific area and hose end sprayers are not known to be very accurate. You will need to mix 0.9 gram of Sedgehammer (using the …

A hose end sprayer would not be the best applicator for a water dispersible granule like Sedgehammer. It is important to make sure the correct amount of product goes over a specific area and hose end sprayers are not known to be very accurate. You will need to mix 0.9 gram of Sedgehammer (using the measuring scoop provided) in one or two gallons of water to treat 1000 square feet. Add 2 teaspoons (1/3 fluid ounce) of nonionic surfactant per gallon of water. Ensure the product is measured as a level scoop and not rounded.

Q

What product would you recommend to spray the infield of a baseball field located in the upstate of SC?
We had soil hauled in from the lower part of SC and placed in the infield. Since that time we have had problems with a grass that some people call nutsedge. We have tried Roundup but it keeps coming back.

A

For nutsedge, the best product by far is Sedgehammer herbicide. Sedgehammer is a selective herbicide that will only kill the nutsedge.

Q

Is SedgeHammer post emergent only? Is it effective as a pre emergent for nutsedge?

A

Sedgehammer is a post emergent nutsedge product only. It will not prevent nutsedge from germinating. Unfortunately pre-emergents do not control summer weeds like nutsedge.
