Product Overview

Quinclorac 75 DF is a water-soluble selective post-emergent herbicide that kills broadleaf weeds and grasses in tolerant turf species. Used as a post-emergent, this crabgrass killer herbicide controls many broad-leaf and grass weeds in turf-grasses on commercial and residential grounds or lawns for homes, airports, athletic fields, golf courses, military and other institutions, parks, roadsides, schools, sod farms.

The weed foliage and roots absorb the Quinclorac 75 DF and translocate it throughout the weed. Treated weeds will show signs of leaf and stem curling or twisting, stunting, change of color from green to white, then to red, before finally dying.

The use of a methylated seed oil surfactant, 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.

    Worked well as suggested

    By Devin on 08/17/2017

    My neighbor doesn't much take care of their lawn except to mow it every month or so, and so their crabgrass was continually growing into my lawn and pulling it up only seemed to spread the seeds throughout my lawn. I mixed according to the instructions, put it down 2 days after mowing and it has killed off probably 80% of what I sprayed. It will probably need another application, but frankly, they were growing a hardy lawn of crabgrass. All the store bought stuff wasn't doing anything so I'm very happy with the results.

    Quniclorac

    By Dave on 07/18/2017

    I have clover and crabgrass so this is my last resort. Applied with Prime Source Duo Stick as instructed. Followed directions to a "T." I'm giving it five stars because the clover and few dandelions I had are dying. Crabgrass appears to be turning yellow. I may have to give another application, and here's why. Weather. It was supposed to be nice with a 20% chance of showers for the few days after my application. Well, the weather people changed their minds the evening of the day I applied and we got 3.13 inches of rain the day after. I'm thinking it didn't stand much of a chance. I think had this not happened it would have been fine. I will say that it already has beaten the usual consumer spreader weed and feeds I have tried in the past. My opinion is positive considering we had our 11th wettest day on record. This is not my first purchase from Domyown Pest Control and I will purchase from them again. They are excellent.

    Great Stuff

    By Patrick on 06/03/2018

    Quinclorac does exactly what is supposed to do but the main reason I love it is because it doesn’t damage your lawn just kills the target weeds that is supposed to Kill I had a bunch of crabgrass and my lawn and is slowly killing it So if you looking for something that will kill crabgrass overnight this product might not be for you but it will kill it while your lawn thrives around it slowly disappearing

Questions & Answers

Have a question about this product?
  
Q
What is the mix rate of Quinclorac 75 DF on a mixture of KBG and fescue?

One part of the label under spot applications says .367oz per 1000 sq ft. In the table it says 1 tbsp per 1 gal. These do not match up in measurements.

A

Quinclorac 75 DF is used at the rate of 0.367 oz per 1000 sqft when applied as a broadcast or spot treatment in a minimum of 0.5 gallons of water.  If you are spot treating with a specific amount of water, ie 1 gallon you would use the 1 tbsp per gallon.

Q
How long does it take to see results on Crabgrass with Quinclorac 75 DF and how long until you can reapply?
A

When using Quinclorac 75 DF the kill time on weeds like crabgrass can vary on mix rate used and the maturity and growth stages of the weed. On average if you are using it with a surfactant it can take at least 14 days after application to see dead or dying weeds. Since summer is not the best time of year to treat for crabgrass and its much harder to control during this time, you may find that the results take longer or may have to do reapplications to get full control. You can retreat after 14-21 days.

Q
Will Quinclorac 75 DF hurt my Bermuda or zoyzia grass if applied when day time temperatures are 90 degrees or higher?

Trying to kill crab grass and some broad leaf weeds

A

It is not recommended to apply Quinclorac 75 DF or any other herbicide when temperatures above 90 degrees Fahrenheit as this could burn turfgrass.  Be sure to apply in the early morning or late evening so that the product has had time to dry before temperatures exceed 85 degrees.

Is Quinclorac 75 DF harmful to animals?

Can this be sprayed if I have dogs? How long do I need to wait to let them on the grass?

A
