Prime Source Quinclorac 1.5L Select Herbicide

Prime Source's Quinclorac 1.5L Herbicide is a selective, post-emergent herbicide that can be safely applied to many types of turf to control a variety of broadleaf and grassy weeds. Quinclorac 1.5L Select can be applied to both residential and non-residential turf. Quinclorac 1.5L Select can be applied from seven days prior to seeding and up to twenty eight days after selected weeds have emerged. The use of methylated seed oil, such as Duo Stick Select is recommended to greatly enhance the effectiveness of the product.

  • Up to 90 day control
  • Works on both broadleaf and grassy weeds
  • Selective control means it doesn’t harm turf
  • Controls Crabgrass
  • Use in conjunction with seeding/overseeding
  • Add Duo Stick Select to enhance efficacy

The Quinclorac 1.5L Select is an 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.

Available in 2 sizes - 7.5 oz and 64 oz. 

7.5 oz size will treat 5,000 sq feet. It is an easy to measure liquid formulation, compared to dry 75DF formulation. 




Broadleaf & Grassy Weeds Controlled:

Barnyardgrass, Bindweed (field), Clover (hop), Clover (red), Clover (white), Crabgrass (large), Crabgrass (smooth), Daisy (English), Dandelion (common), Dollarweed, Foxtail (giant), Foxtail (green), Foxtail (yellow), Geranium (Carolina), Kikuyugrass, Medic (black), Morning-glory spp., Signalgrass (broadleaf), Speedwell (common), Speedwell (slender), Speedwell (thymeleaf), Torpedograss, Violet (wild).

Quinclorac 1.5L Select herbicide may be applied post-emergence to residential and non-residential turfgrasses (refer to Table 1. Turf Tolerance Established) 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, Multifamily dwellings, Military and other institutions, Parks, Airports, Roadsides, Schools, Picnic grounds, Athletic fields, Houses of worship, Cemeteries, Golf courses, Sod farms.

Mode of Action

Quinclorac 1.5L Select is an auxin agonist and is classified as a quinoline carboxylic acid. It 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. Apply Quinclorac 1.5L Select to actively growing weeds as post-emergence broadcast or spot sprays using the turf species, rate and growth stages indicated on the lab.

The use of Quinclorac 1.5L Select before or after seeding or overseeding a turf area will not significantly interfere with the turf grass seed germination and growth of those grass types identified as tolerant or moderately tolerant on the label.

    5 of 5 stars  CrabGrass doesn't stand a chance. Saves your Gr-ass.
    By Paul in Loganville on 07/25/2017

    After failing miserably with name brand products from local retailers, I watched a DoMyOwn video on Youtube to see what to use on crabgrass. I landed on Quinclorac concentrate in an easy-to-use liquid dispenser. I ordered and paid online and was lucky enough to live 18 miles from the warehouse where the package was waiting for me when I arrived 30 minutes later. This stuff needs a surfactant to stop the water from beading up, so add that to your purchase.

QCan you use Prime Source Quinclorac 1.5L Herbicide in the summer with temperatures above 80 degrees?

A

Prime Source Quinclorac 1.5L Herbicide†should be used in temperatures below 85 and not during the heat of the day. †For higher temperature times it would be best to apply in the morning before the day gets hot and the area has time to dry.
