Mixing with water:

Add one-half the required amount of water to the spray tank, then add TZone SE slowly with agitation, and complete filling the tank with water. Mix thoroughly and continue agitation while spraying. When product is left standing for extended periods of time, re-agitate to ensure uniformity of the spray mixture.

Do not use tank additives that alter the pH of the spray solution below pH 5 or above pH 8. Buffer the spray solution to alter pH range as appropriate.

Mixing with liquid fertilizers:

Use suitable sources and rates of fertilizer based upon recommendations of your fertilizer supplier or State Extension Service Specialist.

Verify physical compatibility with a jar test. It can be conducted by mixing all components in a small container in proportionate quantities. If the mixture separates after standing and can be mixed readily by shaking, then the mixture can be used and applied with spray equipment providing continuous agitation.

Adjuvants and spray additives:

Adjuvants (such as surfactants, spreaders, spreader-stickers, spray thickeners, foaming agents, activators, detergents and drift reducing agents) combined with this product can damage the leaf tissue of turfgrass. If any discoloration or cosmetic effects are objectionable or would be unacceptable, then adjuvants combined with TZone SE would not be recommended. Do not use adjuvants and spray additive tank-mix combinations, unless your experience indicates that the tank mixture will not result in turf injury.

    Excellent selective herbicide on cool weather turf grasses

    By Ron on 06/11/2019

    Very satisfied with this product. Mixes easily and stays in solution. Destroys one of the toughest lawn weeds - wild violet - when applied as directed. Lesser lawn weeds stand little chance. While it "suppresses" yellow nutsedge as stated, it does NOT knock it out, use SedgeHammer for that purpose. Doesn't bleach-out desirable turf like Tenacity can and overall is more effective than One-Time. Spot application with a backpack sprayer + correct fertilization and watering = lawn envy.

    Lessons learned after 1 season of experience using TZone SE.

    By Raymond on 12/10/2020

    -It is exceptionally effective and noticably faster than any 3 way or 4 way turfgrass herbicide that doesn't have either sulfentrazone or carefentrazone type ingredients. I've used a 2,4-d 3 way in early spring and saw near zero damage to the weed and TZone killed it without appearing to slow down. Ive sprayed common broad lead weeds in summer when they are not showing signs of active growth and the TZone had almost no effect. Added a soluable nitrogen (ammonium sulfate) and it killed many weeds that aren't actively growing and a common 3 way with nitrogen did nothing. The big shock for me was I really tried to get rid of creeping charlie for 2 seasons and last season Tzone was applied twice in spring and a few days after 2nd app the lawn cut shorter, de thatch raked manually and top dressed the front lawn with 3 cubic yards of very good compost 1/4 inch average depth. The charlie DID NOT COME BACK. I tried really hard to bury it before... applied way to much 3 way my first year that the grass turned pee yellow and died. I hadn't discovered these forums yet. I went a little crazy hand pulling 15+ a day often over an hour with a gardening shovel until I could see zero Roots of rhizomes. Nothing worked and it was spreading to over 1/3 of my front lawn. Say 900 sq ft or charlie with 500 sq ft packed tightly with creeping charlie... .So you can understand that to this day, it blows my mind how easy it All disappeared. Its 6-7 months later and no ground ivy is on my lawn. I saw a few tiny baby creeping charlie after scalping the back yard during a call renovation baby ground ivy is very vulnerable until t Its established. The only mistake I had to make was you need to mix it well. Its a thick milk color and adding water won't mix it like a 3 way. I did a half hearted tank shake and I killed the grass from the bottom part of my tank where it was super concentrated. I did the same error with Tenacity which requires even more energy to mix. I suggest a cordless drill with a long mixing bit. Finally the main con is the price. I bought the largest jug because it's what was available and spent nearly $300. So I never keep it in the heat or cold extremes to add shelf life. everything S

    Creeping Charlie gone

    By David on 10/15/2021

    I am a user of Tenacity but used this TZone SE to target Creeping Charlie with greater efficacy. Worked perfectly.

    Kills Wood Sorrel in Fescue

    By Jpwinston on 05/22/2020

    This seems to be very effective on woods sorrel that was taking over our fescue yard. We also have a problem with wild violets and it has suppressed those but will likely take another spot treatment for those in the fall as the label recommends. There is some browning of the fescue where I spot treated, but it's not severe. I am very pleased so far.

    Great against wild violet

    By Ed on 10/15/2021

    My yard was full of wild violet and nothing purchased at the box stores worked. I saw Videos on TZone and tried it. It works like a dream. Also wiped out some creeping charlie. Definitely worth the money!

What does "dry conditions" mean on the application for TZone? Does this mean that I have to water the lawn 24 hours before and 24 hours after application?

I plan on using this product late June in the Northeast.


If you are in very dry conditions, then you should irrigate the lawn 24 hrs prior to treating with TZone SE Herbicide. It should be applied when you are not expecting rainfall within 24 hours following the application (do not use irrigation/sprinklers etc).
