  • Convenient post-emergent control of both grassy and broadleaf weeds
  • Crabgrass and foxtail control
  • Yellow nutsedge control
  • Wide window of application for broadleaf weeds
  • Protox inhibitor activity for rapid desiccation and death of broadleaf weeds
  • Fast visual response
  • Highly selective on cool-season turf grasses
  • For use on bluegrass, ryegrass, tall fescue and bermudagrass
  • Rain-fast in 6 hours
  • Suitable for applications up to 90 degrees F
  • Water-based formulation



Post Emergent Control of Grassy Weeds

Q4 Plus Turf Herbicide for Grassy & Broadleaf Weeds can provide post-emergent control and suppression of the grassy weeds listed. Apply to weeds during the growth stages. Applications under adequate soil moisture conditions are preferred. Early summer treatments are generally more effective. Applications in the summer (approximately July 15 to August 15) to older, drought stressed grassy weeds are less effective. Late summer applications (after August 15) to mature crabgrass can be very effective. Weed control is affected by the spray volume, timing and the weed growth stages.

Post Emergent Control of Broadleaf Weeds

Apply this product to broadleaf weeds that are young and actively growing for the best results. Spring and fall treatments under adequate soil moisture conditions are preferred to the summer treatments. Generally, summer broadcast applications to older, drought stressed weeds are less effective. Fall applications provide improved control for emerged winter annuals and perennials such as henbit, chickweed, clover and ground ivy.

SPOT TREATMENTS:

  • Calibration and proper application are essential when using Q4 Plus Turf. Spray coverage should be uniform and complete.
  • Over applications can result in turfgrass injury.
  • Cool-Season Turf: 2.6 to 3.0 fl. oz. with 1 gallon of water for treatment of approximately 1,000 sq. ft. of turfgrass. Apply to weeds during the growth stages.
  • Warm-Season: 1.84 to 2.57 fl. oz. with 1 gallon of water for treatment of approximately 1,000 sq. ft. of turfgrass. Apply to weeds during the growth stages.
  • See specific Bermudagrass and zoysiagrass on label.

    5 of 5 stars  Great product
    By Edward on 05/04/2013

    This worked great to kill all the weeds and crabgrass in my 1 acre yard. I used late August of 2012. Used ratio as recommended on label in a 15 gallon tow behind sprayer. I had a little left, so I watered down maybe 1 gallon of the mixture to fill my 15 gallon tank, and it still killed alot of the crabgrass in my neighbors yard. Would buy again.

    Kind of pricey, but you get what you pay for. Works great on getting rid of weeds, but don't get this stuff close to your flowers or they will be gone as well. I highly recommend this product.

    5 of 5 stars  It Works when other stuff failed
    By in Atlanta on 08/08/2013
    Verified Purchase

    I would agree with some of the other comments-there is some investment up front-but it's cheaper than hiring someone and it works. I tried other stuff from Lowes and Home Depot with no luck. Used it in hot weather but had little damage to my Bermuda grass. It killed some pretty large patches of crab grass and other weeds. Pay attention to the proper mix. Would buy again

    By in Central FL on 07/21/2013

    Q4 worked great for the broadleaf weeds and blanket crabgrass in my bermuda lawn. Didn't damage the bermuda much, even though I sprayed when the temps were hot. It didn't work well on the large-leaf crabgrass, but it completly killed the low-growing blanket crabgrass.

    2 of 5 stars  Did not get the desired result
    By Kevin in Columbus, Ohio on 07/29/2017

    I got this after reading several reviews stating it would work well for wide blade grass like weeds. I mixed according to directions, 3 Oz to a gallon. I sprayed it on a few areas and on a few broad leaf weeds. It seemed to weaken things slightly but killed nothing. I waited a little over a week and tried a second round. The surrounding grass seems to be more distressed than what I was trying to kill. Needless to say I'm very disappointed.

    By User1 in aquidneck island, RI on 06/19/2017

    2 of 5 stars  Decent but not as great as I thought
    By James in Riverside, Ca on 05/14/2017

    I was excited about purchasing this product after reading great reviews. The product works but slowly and when I mean slowly, my results took about a week to 2 weeks to start seeing weeds shrink but not completely shrink to nothing either. The weeds were still but in a diminished state albeit dieing state. On a different treatment session, if you spray too much to try to get better or faster results it WILL kill the grass too. By too much, I mean trying to put a slightly more product into the mix or spraying twice in the same area. The product also doesn't prevent near term future weeds from coming back either, just a few weeks after treatment, more weeds sprang up to take dying ones place. I was told by my gardener after treatment it was suppose to last a couple months weed free. The product was very decent and definitely better than what I'm use to using from the big box store Lowes and Home Depot but not as fast and and long lasting as expected.

    5 of 5 stars  This stuff is great!
    By Pk in Indianapolis, IN on 05/11/2017

    Our neighbors had a terrible dandelion problem...the yard was nothing but those yellow flowers. So, we had a dandelion problem. Went to DoMyOwn and after researching and calling customer service with questions, decided on this product. It works! It literally took care of every single dandelion in the yard and fast. You must make sure you do the proper portions and exactly as instructed or you may not get the correct results. We used this product last year and then purchased for this year as well. The product is great and the customer service rep was very helpful in trying to find the right product for our needs. I will only shop on this site for my pesky problems.

QIs Q4 safe for a backyard where a dog would roam. If not, how long after application would be required?
We have a family dog that likes to go in the backyard, but are worried that something this extreme may make him unable to be outside. Is it safe? Once it's dry is it safe? This came highly recommended, but the person recommending it didn't know how it might effect pets.

AIt will be safe for you to apply Q4 Plus Turf Herbicide and allow to completely dry prior to allowing your dog in the treated area.

QWill Q4 Plus Turf Herbicide kill orchard grass?
I just planted my new lawn and have orchard grass growing in it. I believe this came in the topsoil that I put down. The seed that I used was creeping red fescue, camas Kentucky bluegrass, Kentucky bluegrass and perennial ryegrass. If not what other product will take care of this problem?

A

Q4 Plus Herbicide will not kill orchard grass. Unfortunately, we do not know of any selective herbicide that will kill orchardgrass without harming your desirable turfgrass.† It is usually recommended to spot treat the orchard grass as much as possible with a non-selective product like RoundUp QuikPro, and then replant in those areas in a couple of weeks when the orchard grass is gone.†
