    Q
    Is there any more information about Cool Power Selective Herbicide and its toxicity to pets?
    Please share with me any information you have about use of Cool Power and pets on the lawn.
    A

    Cool Power Selective Herbicide is safe for use on lawns when used as directed on the product label.  The general precaution with pets is that they need to be out of the area during treatment and until dry, a few hours is best.  The SDS would have information regarding toxicity.

    A
    The rates when using Cool Power Selective Herbicide will vary depending on the type of grass and weeds you are treating just like with most other herbicides. Rates range from 0.91 - 1.29 oz. per 1/2 - 5.5 gallons of water per 1,000 sq. ft. You can find all the rates by grass type on the product label.  You will also have to calibrate your sprayer if you have not done so. Please watch our video on How to Calibrate Your Sprayer.

  • Asked by Justin from Arkansas
    02/11/2026
    Q
    Can Cool Power be tank mixed with Prodiamine 65 WDG?
    A
    While tank mixing Cool Power Selective Herbicide with Prodiamine 65 WDG would likely be compatible, you should bear in mind that pre-emergents must be irrigated in after applying in order for the active ingredient to penetrate down into the soil to create a barrier in the soil to prevent weed seed germination, whereas a post-emergent would not be irrigated after applying.  Anytime you plan to tank mix various pesticides you should refer to all product labels, adhering to the most restrictive labeling instructions, and mix a small jar test first to confirm compatibility.

  • Asked by Debi from Windsor, Va
    02/12/2026
    Q
    For typical winter weeds that freezing temps don't affect, how much product mixed in 2 gal pump sprayer?
    A
    For typical winter broadleaf weeds that are not affected by freezing temperatures, Cool Power Selective Herbicide is applied based on the area being treated rather than the sprayer size. The labeled turf rate is approximately 0.91 to 1.29 fluid ounces per 1,000 square feet, mixed in enough water to provide even coverage. Most 2-gallon hand pump sprayers apply about 2,000 square feet, so you would typically mix about 2.0 to 2.6 fluid ounces of product in 2 gallons of water. If you are treating tougher winter weeds or spraying fully dormant warm-season turf, using the higher end of the range is appropriate. Apply when temperatures are above roughly 50-65 °F and weeds are actively growing, as coverage and plant activity are key to good results.
