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

Under certain conditions, application of Quinclorac 1.5L Select made to annual grasses at 2 to 4 tiller may not provide complete control. A sequential application will be required for grass control in these situations.

What Does Quinclorac Kill?

Solutions Pest & Lawn highly recommends Quinclorac to our customers and we believe it is the ultimate crabgrass killer. Quinclorac (produced by Quali-Pro) is a selective post-emergent herbicide, which means that it targets specific weeds while sparing desirable grass which may surround the offending weed when applied. Aside from targeting crabgrass primarily, the weeds that quinclorac kills include dandelion and clover which may come up in areas where grass is stressed. Here are a few other benefits which make Quinclorac a solid option for treating controlling crabgrass:

How To Use Quinclorac to Effectively Kill Weeds


Solutions carries Quinclorac 75 DF produced by Quali-Pro. The DF stands for Dry Flowable meaning it is a dry product that should be mixed with water.  Conveniently, the product comes with a measuring device so you can get an accurate measurement of the product before mixing.


1. Measure out the amount you need depending on the size of the land you are going to be treating. The recommended amount of product is .73 oz per gallon of water per 1000 sq ft.


2. Mix up the application. We recommend using a pump sprayer as they are good for selective herbicides and spot treatments.


3. Spray along the areas where you have crabgrass and dandelion or other offending weeds.


4. When applying quinclorac, spray enough to moisten the leaf surface. After about an hour it’s rainfast meaning it will remain on the plant even if it were to rain rather than washing off.


5. About 2 to 7 days later, it is recommend to irrigate the treated plant area so it filters down into the soil to be picked up by the broad leaf plants that you are trying to get rid of. And you’re finished!


After applying Quinclorac according to these steps, give it about a week and check things out. You will notice immediate that the areas of crabgrass and weeds that you treated are dying and turning brown. Be sure to check the product label to see the level of tolerance your desired grass can take as some vegetation is more tolerant of Quinclorac than others.
