I have to spray around my poultry house. I have tried several different versions of Roundup and also several other products. By far the best that I have found is Pramitol. It is made to spray under new asphalt as far as I can tell. All that I know is that I only spray it once a year and that it works. Everything else that I have used, required me to spray 2-4 times a years.
