Product Overview

SpeedZone Lawn Weed Killer Concentrate contains the same active ingredients as the larger SpeedZone EW Broadleaf Herbicide for Turf in gallon and 2.5 gallon sizes.

Speedzone is an excellent selective post-emergent herbicide with superior cool-weather performance and can be used on established cool and warm-season grasses for common and troublesome weeds in turf-grass such as spurge, pennywort, dandelion, and white clover. Evidence of injury can be seen within hours of application, and plants can die in 7 to 14 days. Safe to apply on Kentucky bluegrass, annual bluegrass, perennial ryegrass, tall fescue, red or fineleaf fescue, creeping and colonial bentgrass (excluding golf greens), and mixtures of cool-season species in noncropland (Kentucky bluegrass, tall fescue, smooth bromegrass, and orchardgrass). Uses include institutional, ornamental, and residential sites, sod production, and noncropland (rights-of-way, roadsides, medians, airports, and military installations). Spray solution must be above pH 5 and below pH 8.

Note: Due to New California State restrictions, this Can Not be Sold in California.

    Clovers and Creeping Charlie - gone

    By C. on 07/26/2011

    I have tried just about everything to knock out Creeping Charlie in my lawn. Speedzone did it with ease. The results were noticed within days of the first application. It is an amazing product.

    Well worth the money!

    By Travis on 05/06/2011

    Used and most of the weeds in my lawn were dead the next evening. It took just a couple days on the clover, but it's dead too!!!! Much better than round up and other brands I've used in the past that had little or not effect. I would highly recommend this to anyone wanting to get rid of weeds!!

    Speedzone Lawn Weed Killer

    By Steve on 04/02/2012

    Verified Purchase

    This is the only product I have ever used that is effective in low temperatures. It gives me the ability to kill weeds when they first appear in the Spring instead of having to wait for warm weather to be effective

    Good product

    By Grey on 05/23/2012

    Great product for treating majority of broadleaf weeds and great amount of product if you don't need 1 gallon size. I blanket sprayed at 1.6 oz per 1000 sq. ft. I could see results next day. On the 4th day black medic, clover, speedwell, dandelion are all curled up and brown. Will see the end result and if there are any survivors in 2 weeks.

Questions & Answers

Sort Questions
Does SpeedZone contain a surfactant?

I plan to use SpeedZone for spot treatment of Ground Ivy. Addition of a non-ionic surfactant is typically recommended for liquid herbicide application to broadleaf weeds. I do not see this recommendation on the label, nor do I recognize a surfactant on the ingredient list.


SpeedZone Lawn Weed Killer Concentrate does contain a surfactant and additional one is not required for use with it. The SpeedZone Red which is very similar to the Lawn Weed Killer does state on the product label that adding one may reduce the selectivity on the turfgrass so it could harm your lawn in adding one.
