Just got word from my rep today that Tenacity now has residential approval, at least for Kentucky. Not sure about other states. This is great news for anyone with nimble will problems. Anyone know how it affects common bermuda?

Syngenta Tenacity® Herbicide Approved for use on Residential Lawns
04.01.11
Greensboro, N.C., USA, April 1, 2011
Syngenta Tenacity® Herbicide:
A New Tool for Lawn Care Operators
· Tenacity® herbicide is now approved by U.S. Environmental Protection Agency (EPA) for use on residential lawns.
· Tenacity can be used at seeding, including bare-ground renovation seeding, or selective overseeding. It keeps weeds from germinating and allows new grass to flourish.
· Lawn care operators now have a new tool for pre- and post-emergence weed control on cool-season turfgrasses such as tall fescue, perennial ryegrass and Kentucky bluegrass.
· The active ingredient mesotrione controls more than 40 broadleaf weeds and undesired grasses and sedge, including nimblewill, crabgrass, bentgrass and nutsedge.
· Tenacity is now packaged in 8 oz bottles, making it cost effective and convenient for use by lawn care operators
Syngenta announced that Tenacity® herbicide received registration from the U.S. Environmental Protection Agency (EPA) for use on residential lawns. The selective pre- and post-emergence herbicide controls 46 broadleaf weeds and undesired grasses in most cool-season turf types. In addition to weed control in established turf, Tenacity can be applied at seeding to reduce weed competition for improved seedling development.
“Tenacity provides a unique tool for professional lawn care operators,” said Pat Willenbrock brand manager for Syngenta. “Not only does it deliver pre- and post-emergence control of tough broadleaf and grassy weeds, but it can also be used at seeding to ensure new lawns flourish instead of competing with weeds. This ability for selective renovation provides an outstanding up-sell opportunity overglyphosate or sod options and helps reduce profit-robbing customer call-backs. There simply is no other herbicide available today that does all that.”
Tenacity was granted Reduced Risk status by the EPA due to its active ingredient, mesotrione, which has favorable ecotoxicity and human health profiles, compared to many registered herbicides, reducing the herbicide load on the environment. Its mode of action is novel among turf herbicides, and it fits well into IPM and resistance-management strategies. As Tenacity is not yet registered for use in all states, lawn care operators should check with their state or local extension service prior to buying or using this product.
Mesotrione is based on a compound produced by the bottlebrush plant (Callistemon citrinus). Discovered and developed by Syngenta, mesotrione provides systemic pre- and post-emergence control of numerous weeds including nimblewill, chickweed, clover and yellow nutsedge. Additionally, it is the only herbicide available that offers control of crabgrass both pre- and post-emergence (up to the fourth tiller).
Tenacity has been tested and proven acceptable for use on many turf species including: Kentucky bluegrass, centipedegrass, tall fescue, perennial ryegrass and fine fescue.
As with all pesticides, it is important to read and follow label instructions when using Tenacity. More information can be found at:

i am curious about price as well. we have avoided spraying weeds etc during renovations and of course like to spray them but it seems we would have to charge an extra fee due to high cost of specialty herbicices like this usually have associated with them. but, may be such a low use rate it is not bad. i have never even looked at this product due to knowing it was not for residential use

Isn't this the same as imprelis
It is very close to imprelis but tenacity is labeled for nimblewill whereas imprelis is not, but imprelis may affect nimblewill the same, I not been able to find any test results for imprelis on nimblewill. The price I was quoted for tenacity is $700 ish/gallon. I was wanting to control or damage common bermuda with tenacity. Anyone with some experience?
Interesting with the release date of April fools...
I recently purchased Imprelis but I would like to hear other applicator's Imprelis VS. Tenacity and why you chose one product over the other, or for your particular application (ie at the time of seeding etc)

Good point, is the 8 oz going to be RTU homeowner stuff??
46 States have approved Tenacity for residential use. Florida is one of the four state that didn't approve it. But Tenacity is only labealed for St Augustine sod farms on the New Label.

A couple things from the label...
-No low volume application directions. All directions state to use at least 30gal water/Acre.
-Precautions for fine fescues and ryegrass. This is real folks, it won't necessarily take them out but they will look pretty ugly for awhile. Managing customer expectations is necessary with this, being ahead and explaining what things can look like for a period after application.
IMO, Tenacity is much more of a renovation herbicide for the LCO, compared to Imprelis finding more general use audience. If you're looking at a renovation where there is some decent turf, where killing it all seems a little drastic, Tenacity would be a great fit. It likely will do a little better than Imprelis on Crabgrass and other grassy weeds along with broadleaf control, but I believe Imprelis to be a better option as a 3-way broadleaf replacement.

now that i think about it some more i dont think we can compare this product to imprelis, its label covers grassy weeds and nutsedge
so i will need to do a cost comparison to Q4 plus or solitaire
q4 plus 2.5 gal=$249.90 / low use rate 2.6 oz/k = $2.03/k covers 2.82 acres/jug
tenacity 1 gal = $710.50 / low use rate 5 oz/acre = $.64/k covers 25.6 acres/jug

SquareOne herbicide is another new option recently launched by FMC Professional Solutions. It's labeled for use in most warm and cool-season turf (including bermudagrass) and features a dual combination of active ingredients designed to control crabgrass and many small broadleaf weeds. It can be applied 1 day before seeding or as soon as 7 days after emergence. It's more cost effective than other products, works in a single application, and it won't turn your turf white. You can watch a short 2-minute video or visit www.fmcprosolutions.com for full details.

interesting for sure. thing is, with all these seedling safe herbicides and such, it make it actually more difficult in some ways cuz they arent for use on every lawn so you will have to carry,mix and store more chemicals. sounds like a pain to me
