  • Asked by Valerie from Pequea, Pa
    04/15/2012
    Q
    How much Quick Silver do I mix per gallon of water?
    A
    As with most herbicides 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. In the case of Quicksilver you will need to use 0.021 - 0.154 fl oz per 1,000 sq ft of area. You can apply the specified amount of product in 0.5 to 4.0 gallons (plus specified amount of surfactant) per 1000 sq.ft.. Use higher spray volumes when there is a dense weed population or turfgrass canopy or where uniform coverage is difficult to obtain. For spot treating weeds, other than moss, with hand-held or backpack sprayers mix 0.030 fluid ounces (0.9 milliliters) of this product in one to two gallons of water to treat 1000 square feet. Please refer to the QuickSilver product label for complete usage instructions.

  • Asked by Karen from Grandville, Mi
    08/24/2017
    Q
    What is the use rate of Quicksilver mixed with Tenacity and a Non-Ionic Surfactant?
    How much QuickSilver do I add to 0.5 Teaspoon Tenacity per 1 gallon mix? I'm afraid my math will cause a problem. I purchased .169 fl oz package of QuickSilver. How much do I add to 1 gallon mix? Any Suggestion in how to measure such a small amount of QuickSilver from this packaging to be correct and store any remaining product?
    A

    According to the label, Tenacity Herbicide can be mixed with QuickSilver Herbicide and a non-ionic surfactant. Unfortunately, we don't carry the 0.169 fl oz pack of QuickSilver to be able to give you a recommendation of how much can be used. We recommend reading the label of the product or calling the manufacturer which is FMC, they can be reached at 1-800-321-1362.

    Q
    Will QuickSilver Herbicide kill red sorrel and Hypochaeris radicata?
    Which temperature and wind speed is ideal to apply?
    A

    QuickSilver Herbicide  is not labeled for Hyprochaeris radicata, which is also Flat weed or False Dandelion but will work for red sorrel. Fertilome Weed Free Zone is safe for many turf types and will eradicate false dandelion. We do not recommend applying when there is wind and you should apply to lawns that are not under stressed and when temperatures are above 85 degrees.

    Q
    Can I apply QuickSilver with a hose-end sprayer?

  • Asked by Nicholas from Tampa, Fl
    10/01/2016
    Q
    Is QuickSilver Herbicide the best for lasting control?
    Reviews of Quicksilver say its best at lasting control when mixed with other herbicides to get into the root systems. In addition to the usual southern broadleaf weeds I'm dealing with a seemingly untouchable and very extensive Alligator Weed infestation in a St. Augustine lawn to the point that parts will have to be plugged or sodded after I finally kill these weeds. What herbicide(s) and/or surfactant would you recommend to mix this with for maximum effect on the Alligator Weed without killing the existing grass?
    A

    Unfortunately, QuickSilber Herbicide is not labeled for alligator weed, and would not control it. Most likely in your situation the best recommendation we can make would be RoundUp for spot spraying to get rid of it. There are not other herbicides that are labeled for this except ones that control aquatic weeds.

  • Asked by Dana from Leesville, Sc
    07/16/2018
    Q
    Will QuickSilver kill the invasive prostrate knotweed, spurge that has invaded our Centipede lawn?
    We have irrigation system. We have used pre emergents, post. MSM herbicide with surfactant and no luck. This stuff has taken over our yard and about to lose all of our sod. We have a 24 gallon tank that we pull behind the lawn mover with two spray nozzles. If we have trees in our lawn will it harm them? Do I need to add any thing else to it. When to put it out and how often? Does it kill spotted spurge, creeping spurge, garden spurge, prostate spurge as well? In flower beds grass and gravel driveway.
    A

    QuickSilver Herbicide is labeled for eradicating prostrate knotweed and spotted spurge but not for the other species of spurge requested. It is labeled for applications on established Centipede lawns as they are generally tolerable but they can be sensitive and the product could cause yellowing. Hi-Yield Atrazine Weed Killer is safe for Centipede (if applied as directed) and kills spurge and knotweed.
