    4 of 5 Stars  Killzall
    By Gerald in Prescott, AZ on June 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 water. Will kill everything.

    By Frank in Lancaster PA on May 6, 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.

    5 of 5 Stars  Killzall Weed and Grass Killer
    By John in Baytown, TX on March 7, 2012

    I've been using this product now for several years. If you want to kill something green, this is the product. Just follow the directions and be very careful that you only put it on what you are trying to kill. It has helped me in removing vines/ivy that had been growing for over 15 years; from my home as well as choking 4 of my Oak trees. Since it is not available at any local stores, I was fortunate in finding DoMyOwnPestControl.com. A great company with super prices and fast shipping. And no, I'm not an employee. I do feel that good companies and products should get the cudos they deserve. Both apply here.

    By James in Espanola, NM on August 12, 2015

    I have found that Killzall works better than the higher priced weed killers we have all heard of and paid dearly for. Killzall saves me money and does the job well. I have been using it for approx. 2 years now. DoMyOwnPestControl has great prices, fast shipping, and great products. I always order it from these guys.

    By Tom in New York on June 10, 2015

  • 5 of 5 Stars  Good Stuff
    By Marsh in Pueblo West, CO on June 9, 2015

    Have used Roundup for years. Moved, massive rains, lots and lots of weeds. First round worked pretty well. I would recommend using a NEW spraying unit. My old one wasn't thrilled with the new liquid. I used words you shouldn't use outside enjoying nature. After the right combination of attachments (all new parts) it worked really well. It took 7 days on one patch, and 10 days on the other patch to see really dead weeds. That is with 5 inches of rain rolling over it. Need to order more.

    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.

April 28, 2011 Joel asked:

QCan I use Killzall Weed and Grass Killer around azaleas and flowers?

AKillzall Weed and Grass Killer contains glyphosate which is a non-selective herbicide. Non-selective herbicides will kill just about any type of plant you spray with the product. We recommend Over The Top II for your needs. Over The Top II can be used around azaleas and many other plants to rid your garden of annual and perennial grasses.

May 12, 2011 Randy asked:

QDoes Killzall loose any of its potency after it has been in sub-freezing temperatures for the winter?

AIt is not recommended to leave any type of chemical in areas where they could freeze or over heat because of the potential for the chemical to break down. According to the manufacturer, as long as the Killzall Weed and Grass Killer was only exposed to sub freezing temperatures for a short period of time and the product looks exactly the same as before it was exposed, it should be fine.

June 20, 2013 George from Huntersville, Nc asked:

QIf I mix more Killzall than I use, what is best way to store it?
My Stihl backpack sprayer sepcifically says to empty it after spraying, rinse it, and let it dry. I destroyed another, less expensive sprayer by leaving mixed Killzall in it. Would a plastic gas can withstand the prolonged exposure. I can't always predict how much mixed Killzall I'll need, and I don't want to just waste it.

AThe recommendation for not leaving mixed solution in your sprayer is not only because it can damage your sprayer, but the solution is not good if left mixed more than 48 hours. Any time you spray you should only be mixing what you will use for that treatment and no more. Anything left over should be disposed of in the proper manner for that product, so if you have to, mix up less than you think you will need to avoid waste.

July 23, 2015 Jill from Texas asked:

QWill overspray Of KillzAll hurt heirloom specialty day lilies when using high concentrate to kill horse nettle?
I have horse nettle, Solanum Carolinense, growing rampant taking over flowerbeds with heirloom specialty day lilies (mostly) and other flowers. I've tried killing it over and over again with various products. It won't die. lol. I found a website which suggested 'I have had the best luck by waiting until they have grown fairly large in July and then painting all the leaves with a 50-50 mixture of glyphosate and water. By late August smaller Horse nettle plants will root-sprout, that is when I give them another treatment. After a few years most of these nettles have disappeared.' They are so thick that I would rather spray with a hand sprayer but am very concerned about the possible effects on the lilies, especially at the 50-50 mixture which is apparently necessary to kill this evil plant (what we called it for the last 12+ years before Google helped to identify it). I've looked at a bunch of websites and none of them list lily as being killed by Glyphosate, but how do I know it's an inclusive list?

A

KillzAll Weed and Grass Killer is labeled to control Horsenettle but should not be used any stronger than as directed on the product label. Use 2.5 oz. Killzall per gallon of water. It will pretty much kill anything it is applied to, and any drift or overspray could harm other plants that are contacted. Glyphosate is a non-selective herbicide, so any product containing this active ingredient will affect any plants that are sprayed with it.

QHow should I apply Killzall Weed and Grass Killer - 41% Glyphosate to old, large poison ivy vines growing up trees with leaves in the tree's canopy?
I see where you told Brad from Los Lunas, New Mexico to be sure that you do not spray the bark directly and avoid any exposed roots on trees. I have old, large poison ivy vines growing up trees. Do you have any recommendations? All I can think of is a paintbrush to 'paint' the poison ivy vine, but I don't want to risk damaging trees. Most of the foliage is up in the tree's canopy so I don't have a chance of applying Killzall to them. Will 'painting' the vine kill the poison ivy?

A

When using Killzall Weed and Grass Killer, it is not recommended that you use the product on a desirable plant or tree. You can spot treat the ivy in areas where they are, but the safest way will be to cut the ivy that is on the tree and spray the areas where ivy is elsewhere.

May 2, 2015 Katie from Round Lake, Il asked:

QHow safe is Killzall Weed and Grass Killer for the garden?
If I spray it, will it go to the root to kill it? Will it deep intot the soil and spread to other plants even if I don't spray those plants directly? Also how far from water life can you spray this? We have a pond further behind our house, but it is a good 30 feet or so from the edge of the garden I think.

A Killzall Weed and Grass Killer is a non-selective post-emergent weed killer that will kill any weeds or grasses sprayed directly. It will not penetrate deep into the soil and does not have any residual soil activity. It will be safe as long as you are careful to avoid spraying the desirable plants. It should NOT be applied where runoff could occur or around any acquatic life or bodies of water.  However, we do carry a glyphosate product that is made specifically for use around bodies of water.  It is called Rodeo and you should use a surfactant with it for better results.  You would wait 48 hours after application before using the water. It is recommended that you wait 1-2 weeks before replanting in an area that has been treated with a glyphosate product such as Killzall Weed and Grass Killer.
