    Q
    How much QuinKill Max Crabgrass and Weed Killer do you mix with a gallon of water?
    A
    The label states to use 1.45 oz QuinKill Max Crabgrass and Weed Killer per 1000 square feet. You also must know that when using an herbicide such as QuinKill Max Crabgrass and Weed Killer is that the exact amount of water you dilute it with is not important. It is only important to make sure you are using the correct amount of product per 1,000 sq ft of lawn. Use too much and you risk damaging your lawn, use too little and you will not get adequate results. You will need to use 1.45 oz per 1,000 sq ft . To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with WATER ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix 1.45 oz of product with for each 1,000 sq ft area that needs to be treated.

    Q
    How do I kill crabgrass in Bermuda grass?
    I used a pre emergent but have tons of crabgrass in my lawn. Should I use a post emergent to kill them? If so,which brand do you recommend that will not kill my bermuda?
    A

    You could use a post-emergent to control it or you could even use a pre-emergent product called Dimension which also has very early post emergent crabgrass control.  For post emergent, QuinKill Max would be a good choice to use.

    Q
    How soon can I apply a second dose of QuinKill Max Crabgrass and Weed Killer to the crabgrass that appears to not be affected by the first dose?
    I applied QuinKill Max Crabgrass and Weed Killer along with Speedzone and a sticky agent. Most weeds are dead or dying, but some didn't seem to be affected. It was morning with dew on the grass, so I feel I need to reapply in the evening. How soon can I do that? Is spot treatment OK in that case? Having lawn plugged and seeded in a couple of weeks, so am in a hurry.
    A

    QuinKill Max Crabgrass and Weed Killer can be reapplied 2-3 weeks after first treatment. It is normal not to see a burn down just yet. This can tak at least 2 weeks to occur.

    Q
    Is QuinKill Max safe for southern lawns? specifically st augustine grass?
    A
    QuinKill Max Crabgrass and Weed Killer cannot be used on St Augustine grass, Bahiagrass, carpetgrass or dichondra. Unfortunately there really isn't a post-emergent crabgrass killer that can be used on St Augustine grasses available unless you are willing to go to a higher price point. We do carry Echelon 4SC and it is labeled for use on St Augustine. Still the product label does warn "Application of Echelon 4SC to St. Augustinegrass may cause temporary discoloration to exposed leaf surfaces of St. Augustinegrass. Treated turfgrass will
    recover with new growth and discolored leaf tissue will be removed with mowing."

    RE: QUINCLORAC
    Please provide information on the above application for Torpedo grass.
    A

    According to table 3 on page 14 of the QuinKill Max Crabgrass Label:

    For broadcast applications mix 64 fl ozs of product per acre.

    For Spot applications, mix 1.45 fl ozs per 1000 sq ft. The amount of water is determined on how much it takes to cover a 1,000 sq ft area.

    One Quart controls over 20,000 sq ft or 1/2 of an acre
    One Half Gallon controls over 40,000 sq ft or 1 acre
    Use 1.5 oz (3 Tbsp) per gallon for spot treatment

  • Asked by Brian from Draper
    05/01/2014
    Q
    Which product is better, QuinKill or the Bayer Advance All In One?
    QuinKill and Bayer both have the same active ingredient (Quinclorac) but at different concentrations. When both products are properly diluted, is the amount of quinclorac applied actually the same? I want to use something as effective as QuinKill for my crabgrass, but I don't need a lot, which is why I am considering the Bayer RTU product.
    A
    If you do not need a lot of product then we would definately recommend the Bayer Advanced All-In-One Lawn Weed and Crabgrass Killer’s RTU as it is less expensive, no mixing required, and works just as well as QuinKill Max.

  • Asked by Quintin
    04/06/2018
    Q
    Which is better, Quinkill or Tenacity?
    Looking for something that will kill grassy weeds & crabgrass but also can be applied when overseeding that won’t hurt new seeds.
    A

    Tenacity is typically the choice for a pre-emergent herbicide needed when seeding or overseeding a lawn, particular tall fescue or other cool-season grasses. For QuinKill Max, you will need to consult the chart on pages 15-16 of the product label for appropriate timing depending on the type of turfgrass. Some grasses are more tolerant of this herbicide than others.

    Q
    Can QuinKill be applied effectively in the fall?
    A

    Applying Quinkill later in the season will not be very effective in killing crabgrass as it is better controlled when still young and not large.  We have a great article here that can advise on the best time and treatments for elimination.

  • Asked by Billy from Sterling, Va
    06/07/2016
    Q
    What else do I need for crabgrass control?
    I've been trying to battle crabgrass forever. I've made three applications of the Hi-Yield crabgrass weed control since March 1st..and as well over-sprayed with the 2EW product. .25 oz. to 1 gallon. So far, I'm seeing little results and the crabgrass is thriving. What do I do? The temps are in the 80's now. Is there any hope at this point?
    A

    The Hi-Yield Crabgrass Weed Control and Dimension 2EW are primarly pre-emergent herbicides and will not control existing crabgrass. Dimension 2EW will have early post-emergent control of crabgrass, but only until about the second-tiller leaf stage. For better post-emergent control of crabgrass, we would suggest using Quinkill Max, which contains quinclorac. Quinclorac is the most popular post-emergent herbicide for crabgrass on cool-season turf. Be sure to use a surfactant such as Prime Source Duo Stick with QuinKill Max. This surfactant greatly helps reduce surface tension of applications to maximize absorption of the herbicide into the target plants. Post-emergents will work best on young, actively growing plants.

  • Asked by Bob from Glenbeulah, Wi
    05/14/2017
    Q
    How many ounces do I use per gallon to spot treat my crab grass with QuinKill?
    I don't want to know how much per 1000 square feet. I want to know for spot treating purposes. I've been using 1.5 oz per gallon, results non existent. Should this product kill dandelions?
    A

    As with most herbicides like QuinKill Max the exact volume of water is not very important, you just need to be sure you are getting the correct amount of product on a specific area.  Generally speaking 1 gallon covers 1000 sqft, so you can apply 1.45 fluid ounces in 1 gallon for spot treating. QuinKill can kill common dandelions but does state on the label Tank mix partner or sequential application required.  Did you use a methylated seed oil surfactant which is required for use with this product?  If you did not use a MSO with the product that could be the reason for not having success.  Also the active ingredient in QuinKill is a slow kill can take up to 6 weeks to kill sprayed weeds when used as directed.

    Q
    It says not to use QuinKill Max on Bahia or St.Augustine, but can it be used in a spot treatment manner?
    A

    QuinKill Max cannot be used on Bahia or St. Augustine grass.  If you need to spot treat, you can also always use a non-selective herbicide such as RoundUp QuikPro and then replant in those areas.
