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.

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).

Is TZone SE Broadleaf Herbicide for Tough Weeds safe to use with young spring grass just now coming up?

What I understand this won't hurt my current lawn it is Fescue, is this true? Will it hurt grass that is coming up now from seed?


TZONE SE Broadleaf Herbicide for Tough Weeds should not be used on warm-season grasses during Spring green-up or in the Fall when the grass is transitioning into dormancy. This would be applied to warm-season grass only, such as Bermuda and Zoysia. TZone is safe to use on established tall, red, or fine leaf Fescues. If you have just put down new seed, then you should delay using TZone until after the new grass is established (after the 2nd or 3rd mowing). Treated areas may be reseeded 3 weeks after application. Please refer to the product label for complete application instructions and precautions.
