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?
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.
