Atrazine will kill grass and weeds. If you use it be careful because it will leach very easily during periods of rain. Any low spots will get a good dose of spray resulting in lots of dead grass or at the very least very yellow grass.
Where does some "guy in the neighborhood" get a RESTRICTED USE pesticide? And what does he know about safe application? Forget atrazine unless you are really up on your pesticide licensing and education.
Just got a bottle of Atrazine.Home Depot has like a hundred of them there they are still available and they are still getting more.Can`t wait for it after the my St.Aug gets a wiff of it.It should be the best on the block after I spray it.
