Quinclorac 1.5L is a liquid post-emergent herbicide that gives you unparalleled control over crabgrass and other related broadleaf weeds and grasses. Applicable in both residential and non-residential turfgrass, golf courses, and parks, the product's liquid formulation provides higher quality results when compared to dry formulations. Make sure to apply other herbicides to your property to control for weeds that the product does not cover.
The use of a methylated seed oil, such as Duo Stick Select is recommended to greatly enhance the effectiveness of the product.
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.

Apply QUINCLORAC 1.5 L to actively growing weeds as post-emergence broadcast or spot sprays using the turf species, rate and growth stages.
For best results, weeds should not be under stress from lack of water, excessive water, low fertility, mowing shock, excessive hot or cold temperatures, or injury from other herbicide applications. To achieve consistent weed control, use methylated seed oil. Refer to Tables 2 and 3 for rates.
Adding adjuvants may cause slight leaf burn, but new growth is normal, and turf vigor is not reduced. The potential for leaf burn is increased when relative humidity and temperature are high. Additional stress from low mowing heights may also increase the possibility of turf injury. Chelated iron or sprayable soluble nitrogen fertilizer will reduce a slight yellowing that may occur on some turf-grass species. Not all chelated iron or sprayable nitrogen fertilizers are compatible with QUINCLORAC 1.5 L. Always perform a compatibility test to ensure proper mixing. See Compatibility Test For Mix Components section of label for directions.
Spot Applications:
Post-emergence spot applications may be made to susceptible weeds in turf-grass that is tolerant to QUINCLORAC 1.5 L (see Tables 1 and 2). Apply 1.45 fluid ounces of QUINCLORAC 1.5 L per 1000 square feet (0.75 lb ae/A) of treated area. Spray coverage should be uniform and complete. See Table 5 for spot spray mix instructions.
For use in New York State by spot treatment only.
Works on Torpedograss

Control of existing torpedo grass/Northern Florida
By Michael on 07/31/2020
Tried for 3-4 years to kill torpedo grass in a zoysiagrass lawn. Used commercial spraying multiple times - at first sign/after growth/post emergence - with pretty much no results. Used this product as directed, and after 5-7 days torpedo grass had yellowed significantly. Reapplied 16 days later, as directed, and it stopped noticeable growth and basically killed off torpedo grass in the lawn.

Waste of time and money

Prime Source Duo Stick is the MSO type surfactant we would recommend for use with Quincorac 1.5L as well as any other quinclorac specific crabgrass control product.
