Best time to use it?
Quinclorac 75 DF should be applied when the ground is not frozen and rainfall/snow is not expected for more than 24 hrs. You want to treat when the weeds when they are actively growing for the best results. We recommend to make the application in the cooler times of the day also when temps are between 65-80 degrees.
