How warm does it have to be to apply Q4 Plus Turf Herbicide?


The product label for Q4 Plus Turf Herbicide states that you should not apply the product above 90 degrees. Although it does not give a specific temperature for being too cold, most herbicides should be applied between 65 degrees and 85 degrees, when the target weeds are actively growing.
