  • Asked by Therese from Boise, Id
    06/15/2018
    Q
    I have applied Killzall 3 times in 1 week and the weeds don't seem to be dying. What should I do?
    A

    Killzall Weed and Grass Killer - 41% Glyphosate can take up to 2 weeks to completely kill weeds and applying it more often or higher than the labeled rate does not make it work faster or better.  In fact, this can actually stress the weeds, making them less likely to absorb the product and die from it.  It does only kill the weeds it is directly sprayed onto and does not prevent anything new from growing in the area.  The rate used sound to be way to much for such a small area, the highest rate you should use is 2 ½ oz per gallon of water to treat 300 sqft per the product label.  At this time we would advise to wait at least 2 weeks from last application and try reapplying ad the labeled rate.  Be sure weeds are actively growing and healthy and are not heat or drought stressed for best results.

    05/21/2012
    Q
    Does Killzall Weed and Grass Killer kill ragwort? Is Killzall safe to use around kids, ducks and horses?
    A
    Killzall Weed and Grass killer is labeled for ragwort and should do a great job helping to eliminate this weed. Keep pets and children away from the area while you are doing the treatment and they can return after the application has had a chance to dry. Do not treat any areas where the horse is known to graze or in areas that you will harvest the plants for feed. You should note that Killzall is a non selective herbicide which means that it can kill just about any plant that is sprayed. Please read the Killzall product label for complete usage instructions.

  • Asked by Jill from Texas
    07/23/2015
    Q
    How 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.

  • Asked by Katie from Round Lake, Il
    05/02/2015
    Q
    How 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.
