I bought a bottle of Roundup from WM. I coulkdnt mget the directions to seperate and so called them. They said take a cap full of concentrate for gallon. Im not sure that is right. Whats your thoughts? Also, Im wondering, since he had to look through more than the listing on the back ob bottles there as they didnt have it listed on their grasses that it kills, would it hurt anything to mix gas or Diesel in with the water when I spray it on?? Its in a garden thats being taken 1/2 over so far. Its a drouth yr here and so im not expecting much out of the garden anyhow, which makesa it a good year to kill this stuff. Also, do goats like poison ivy?
