    Q
    Is Q4 safe for a backyard where a dog would roam. If not, how long after application would be required?
    We have a family dog that likes to go in the backyard, but are worried that something this extreme may make him unable to be outside. Is it safe? Once it's dry is it safe? This came highly recommended, but the person recommending it didn't know how it might effect pets.
    A

    It will be safe for you to apply Q4 Plus Turf Herbicide and allow to completely dry prior to allowing your dog in the treated area.

    Q
    How to treat my lawn for weeds without killing my grass?
    I have fescue grass with many types of weeds I am new to treat lawns so I need help choosing a product. I have a lot of green clover and dandelion. I have sprayed amine 400(2,4-D) but it has not really done the perfect job I seen the dandelion die but clover is unaffected by this product.
    A

    Q4 Plus is highly selective on cool-season turf grasses such as fescue and works extremely well on various broadleaf weeds including clover.

  • Asked by Mj from Roswell Ga

    Q
    Sprayed my yard with Q4 but had heavy rain 4 hours later. Should I re-apply?
    I sprayed my Bermuda grass with Q4 about 11:30 am as the forecast did not call for rain till the next day. About 4:00 pm it poured rain for a good 45 minutes to an hour. I read the product is rain proof is 6 hours, but this was not quite 6 hours and the rain was very heavy. Should I re-apply or what?
    A

    Were the rain to be a light sprinkle then the 4 hours should be okay, but with a heavy rain for that length of time we would suggest reappying the Q4 to ensure you get the accurate results you are looking for from this product. Please let us know if you have any other questions.
