The use of a methylated seed oil, such as Duo Stick Select is recommended to greatly enhance the effectiveness of the product.

The Quinclorac 75 DF Select is a herbicide that is used for cool season turfgrasses. It can be used for both residential and non-residential areas in a wide range of turf species. This herbicide is great to use for post emergence control of barnyardgrass, crabgrass, blackmedic, clover, dandelion, annual foxtail, common slander and thymeleaf speedwell.

For use in California: Biotypes of large and smooth crabgrass in California have shown varied response to this product. If control failure occurs following a full or split application, DO NOT reapply this product. Change to a herbicide with a different mode of action.

Quinclorac Select 75 DF Herbicide may be applied post emergence to residential and nonresidential turfgrasses (refer to Table 1) for the control of many broadleaf and grass weeds. Examples of such sites include, but are not limited to: grounds or lawns around residential and commercial establishments, multi-family dwellings, military and other institutions, parks, airports, roadsides, schools, picnic grounds, athletic fields, houses of worship, cemeteries, golf courses and sod farms.

Quinclorac Select 75 DF Herbicide is absorbed by foliage and roots and translocated throughout the plant. The control symptoms exhibited by broadleaf weeds include leaf and stem curl or twisting, and chlorosis. Susceptible grasses demonstrate stunting, chlorosis, and gradual reddening followed by necrosis and death. Refer to Tables 1, 2 and 3 for turfgrass tolerance and susceptible weed species.

APPLICATION:

  • Approximate use rate: 1 pound per acre.
  • Spot spraying: 1 tablespoon of Quinclorac plus 1 tablespoon Duo Stick Select in enough water to cover 1000 square feet.
  • The label recommends the use of a Seed Oil. We offer Duo Stick Select in quarts and gallons; normal use rate is approximately 32 ounces per 100 gallons water.

Note: Please see Product Label for complete list of Application Rates and Mixing Instructions.

    This Product Works

    By Patricia on 03/19/2021

    I use this later in the crabgrass growing season if I missed some with the pre-emergent. Takes care of it with no problem.

    Knocks out post emergent crab grass

    By Mark on 08/19/2022

    Does an amazing job for spot treatment of post emergent crab grass. Better to avoid this issue with pre-emergent treatment, but when all else fails Quinclorac takes care of the problem, with crab grass dying within 1-2 weeks of application.

    Works great

    By Dave on 06/03/2022

    Started out using this for crabgrass but have since been using it for spot treating weeds. It works great on both. I fought crabgrass for a long time until finding Quinclorac and now the rest of the weeds get the pleasure of meeting it too.

Q
Regulated in NYS?

I need a professional strength post emergent herbicide as the commercially available herbicides at lowes and home depot wont kill foxtail. Professional sevices are price gouging us here in NY. I will buy this product asap if it is non regulated in NY. Thanks Robert

A
Select Source Quinclorac 75 DF Select Herbicide is restricted to NY. Acclaim will treat for Foxtail and can nbe shipped to NY. Be sure to review the product label that the turf grass you have is tolerant to it.

Q
If I mix Quinclorac with Tzone, should I add methylated seed oil to the mix?
A
We do not recommend mixing Prime Source Quinclorac 75 DF Select Herbicide with a product such as TZone herbicide. Quinclorac requires the addition of an MSO surfactant, however you should not add a surfactant like that to TZone as this would likely damage your desirable turfgrass. 

We recommend applying a quinclorac product with the MSO surfactant as a separate application. Otherwise, you may consider using Q4 Plus Herbicide which has quinclorac plus some of the same active ingredients as TZone.
