The yard in question is centipede grass. Heavily covered in both henbit and white clover. Following directions, I applied the 4% Atrazine. Henbit has turned brown and died. The white clover is not showing any signs of ill effect. Questions: 1. I understand Atrazine will control white clover. Correct? 2. If so, how long should it take? 3. Have been advised to try 2,4D at a reduced rate. Thoughts? 4. If Atrazine won't do in the clover and you don't recommend 2,4D then can you suggest something else? Thanks for any help.
