It should be applied when bees are not foraging and away from bodies of water (areas of drift also). You should NOT apply through irrigation systems as well. It should be used for spot treatments in lawn, mulch beds, flower beds, around patios, walkways, fence lines and driveways.

BurnOut Weed & Grass Killer Concentrate is a non-selective herbicide, so it would kill just about anything it is sprayed on, including centipede grass. You may want to consider a product like Blindside instead, which is labeled for crabgrass and clover and would be safe to use on centipede grass.
