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

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.

Great Stuff

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

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.

Quinclorac 75 DF will not harm Empire Zoysia when applied per label. We recommend to make the application in the cooler times of the day also when temps are between 65-80 degrees.

If it is recommended can you suggest the lowest cost option for a surfactant? I have been able to identify non-ionic surfactants but the ingredients vary greatly. I would be looking for the best formulation at the least cost.
Yes, when using Quinclorac 75 DF you would want to use a Non-Ionic Surfactant for hebicides like Prime Source Duo Stick.

Trying to kill crab grass and some broad leaf weeds
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.

The common product which contains Quinclorac in part does not seem effective for crabgrass in the 80-95 degree days in summer.
Quinclorac 75 DF should be applied only in temperatures below 85. You should apply in the early morening or late evening on hot temperature days. The product label does state the following regarding crabgrass: Complete control may not be achieved under certain conditions to crabgrass at 2 - 4 tiller stage. In these cases you will need to make a sequential application for control. For best results apply with methylated seed oil either before the second tiller stage or as the weed grass mataures. You should treat whenever the crabgrass has just emerged or after it has matured for best results, whenever this is in your area. You can also check with your local cooperative extension office for the best advice on timing.

New York is a very tough state for homeowners to purchase the professional grade products we carry like Quinclorac 75 DF. The states prefers that only licensed trained professionals handle the product and many others. A great alternative is the Ferti-Lome Weed Out with Crabgrass Killer: it contains the same active ingredient.

If so, what sprayer setting?
Quinclorac 75 DF is not recommended to be used in a hose end sprayer. The first thing you need to know when using an herbicide is that the exact amount of water you dilute it with is not important. It is only important to make sure you are using the correct amount of product per 1,000 sq ft of lawn. Use too much and you risk damaging your lawn, use too little and you will not get adequate results. To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with water ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix for each 1,000 sq ft area that needs to be treated. You will need to make sure treated areas are irrigated with at least 1/2 inch of water (either by rainfall or by sprinkler) following the application.

I have 2 large sycamore trees which are growing in a lawn of tall fescue. Lots of crabgrass have invaded as have many sycamore saplings.
Quinclorac 75 DF is absorbed by foliage and roots and is translocated throughout the plant. It should not harm mature trees or desirable plants when used as directed.

You should be able to safely mix the Quinclorac 75 DF with the Speedzone to get a wider range of weed and weedy grass control with no issues. As with any chemical mixture, be sure to do a tank mix test first to make sure no clumping or mixing issues occur and spot test a small area to be sure no undesirable effects occur from the mixture and use. Always follow the most restrictive label of the two for use. Per the Quinclorac 75 DF product label, only use on fine fescue if its incorporated into a fescue blend as some turf damage or discoloring could occur if its a fine fescue lawn only.

Quinclorac 75 DF are tan pellets and the Quinclorac 1.5L is a liquid. They both contain the active ingredient, quinclorac but are different formulations made by the same manufacturer. Please refer to the product label for the specific application instructions to fit your needs.
