Will Atrazine 4L kill Bermuda grass in my Centipede lawn if so how do I apply it?
Chuck on Feb 2, 2018
BEST ANSWER: It would not kill Bermuda but it would cause injury if applied to Bermuda during the growing season. It would also affect newly seeded Bermudagrass. The best option in killing Bermuda is to spot treat it with Glyphosate making small application at a time allowing the Centipede to grow over the bald spot.
