By Gerald in Prescott, AZ on 06/10/2011

I have been using this product for a few years. It works slowly (4-6 days) to really see benefit but sprayed area lasts pretty well. The best thing is that you need only use 5 tablespoons to gal of wa…

Killzall weed and grass
5 of 5 stars
By Frank in Lancaster PA on 05/06/2011

A little slow in killing but most effective. Took about five days to kill all in the area that was sprayed. I did not see any affects of runoff from rain to surrounding plants or shrubs.

By Jr in Atlanta on 06/10/2014

I have bought this before and will buy it again. Roundup is 41% Glyphosate - That uis the active ingredient. Killzall Weed and Grass Killer is too. Why pay $160 for the name brand Roundup? Don't buy a…

By Linda in Chicago suburbs on 10/11/2015

First of all, trying to interpret the ratio of Killzall to use in a hose distributor bottle is so not clear. I guess they want you to buy a Killzall hose distributing bottle. I sprayed at least 7 day…

Expert Response  Expert response:

We apologize you had some issues using the Killzall. The Killzall label does have a specific mixing instructions graph that lets you know exactly how to use the product in different types of hose end sprayers (ones that you just add chemical to the small tank and the other type where you chemical and a certain amount of water to the small tank). They only list the ones they manufacturer because there are 100's of brands on the market and they all work a little differently. The hose end sprayer usually comes with instructions that explain how to use liquids in the sprayer. Is it possible your hose end sprayer was not properly calibrated? This could be the reason why you are not seeing the expected results. We would recommend using a hand pump sprayer or making sure you hose end sprayer is properly calibrated and spraying the weeds again. It is also important to note that Killzall will only work on actively growing weeds and should not be used directly after or directly before cutting or mowing as the plant will not absorb the product. You should give the product about 14 days to show results. Please let us know if we can be of further assistance. We are always happy to help!

It doesn't have expensive TV or magazine ads, nor does it come in a dozen different formulas. It does what it claims to do.

Not impressed
1 of 5 stars
By Dennis in San Diego, CA on 01/27/2015

Followed the directions, a week later weeds started to get a little yellow. Had to spray again. Still not happy. You would think with a name like Killzall, everything would die.

Expert Response  Expert response:

Any post-emergent herbicides will work best when the plants are actively growing, as this will cause the active ingredient to translocate through the plants much more quickly. Be sure to follow the label directions to use the best dose for the plants you are targeting. More mature plants or woody/vine species may require multiple applications. We are always happy to discuss your treatment over the phone at 866-581-7378 M-F 9a-5p EST.
