    Q
    Will Certainty Herbicide kill oxalis and dandelion in dwarf mondo grass?
    A

    Certainty Herbicide is safe for mondo grass, but it is not labeled for oxalis. We would recommend a product like Monterey Weed Whacker, which is labeled for both oxalis and dandelion, and is safe to apply to established mondo grass.

    Q
    Can I apply Atrazine while the zoysia / centipede grass is dormant?
    I am considering Atrazine to kill or at least control the poa annua. I have a zoysia lawn, however, I have had some centipede creep in over the years mixing with the zoysia. Once it is out of dormancy, can it be applied then as well? I have tried the expensive pre-emergents but they seem to be a waste of time and money.
    A

    We cannot recommend that you use any Atrazine product on your zoysiagrass since it will not be labeled as safe to use on this type of grass. A better choice woud be something like Certainty Herbicide which is labeled for post-emergent control of poa annua in both zoysia and centipede grasses. If you are having trouble with pre-emergent control of this weed, then you may need to adjust the timing of your application and/or consider rotating the active ingredient you are using.

    Q
    I am looking for the herbicide for dandelions, chickweed, and clover. I have tall fescue.
    A
    Certainty is not labeled for use on Fescue.  It actually will kill the fescue. 

    Our most popular general weed control product that is selective, meaning it will not harm your turf grass but it will kill your weeds, is End Run.  

    End Run is labeled for just about any weed you could have including clover, dandelions, and chickweed and will not harm your grass.  Best of all, it comes with a surfactant already mixed in the product so you do not have to purchase and mix a surfactant separately like you do with most of the other herbicides that we sell.

    Here is a link to the End Run:  http://www.domyownpestcontrol.com/endrun-herbicide-with-trimec-p-1501.html

    Please let me know if you have any further questions.

    Q
    Will Certainty kill Chamberbitter without harming St. Augustine?
    I live in East Texas. These things look like miniature Mimosa trees, and they are very prolific. They are apparently quite hardy, Sedge Hammer won't kill them.
    A
    We recently started carrying herbicides due to customer request, but they are not yet our specialty.  We would like to refer you to the manufacturer since they are the experts on their Certainty product.  The manufacturer is Monsanto and you can reach them at (800) 332-3111. You can also contact your local cooperative extension office and request advice from the local master gardener who is well versed on the plant life in your region.

    Q
    Will Certainty Herbicide also kill spurge in a Bermuda lawn?
    Will it kill splurge and how long do I have to spray before overseeding my bermuda lawn with perennial rye?
    A

    Unfortunately, Certainty Herbicide is not labeled for spurge. We would recommend a product like Monterey Spurge Power, as it is labeled to be used in a Bermuda lawn. You would not want to do any seeding any sooner than 3-4 weeks after application of this product.

  • Asked by Shaun from Braselton, Ga
    02/24/2019
    Q
    How long before noticing any symptoms on weeds especially poa annua when using Certainty?
    A

    You may notice signs of the poa dying (discoloration-yellowing or browning) within 2-3 weeks after you have applied Certainty but it is normal not to see anything for at least a month. Per the product label, you can make an additional application 4 or more weeks after the initial application as needed. Best results are obtained when target weeds are actively growing & not disturbed by mowing for at least 2 days before and 2 days after application. Warm, moist conditions following application will accelerate activity; cold, dry conditions will delay activity. Drought stressed weeds are less susceptible.

  • Asked by Jason from Atlanta, Ga
    03/10/2018
    Q
    Is anyone know the easy way to apply Certainty Herbicide using a hose end sprayer?
    I got 14,000 square feet to spray.
    A

    Certainty Herbicide like most other herbicides should not be applied in hose end applicatiors. This type of sprayer sometimes is not very accurate, so you can wind up dispensing more/less product than needed in a given area, which can lead to less than desirable results.

    3 - 5 small scoops or 1 - 2 large scoops per gallon of water per 1,000 sq. ft. 
    * Use a Surfactant to Increase Effectiveness 
    * See label for complete application instructions
