This herbicide effectively controls crabgrass, Bermudagrass, quackgrass, foxtail and other weedy grasses. The product is best used when added at 1 oz. per gallon of water. Once applied, the grass will stop growing, will turn reddish then yellow and will die in 1-3 weeks time.

Can Monterey Grass Getter be used to kill/suppress bermuda grass and not harm centipede grass or oak trees?
Monterey Grass Getter Herbicide is a grass killer so it would harm or kill the centipede grass in addition to the Bermuda. It is is only meant to be used around flowers, evergreens, ornamental groundcovers, bedding plants, shrubs, trees, fruits, and vegetables. It would not harm the oak tree. We actually do not carry a product that is labeled to remove Bermuda grass from centipede. The only suggestion we can give is to kill the Bermuda with a glyphosate product and then re-seed the centipede in those areas.
Unfortunately, Bermuda grass is so closely related to St. Augustine grass that there is nothing that will remove Bermuda from St. Augustine and not hurt the Bermuda as well. In your situation it is recommended to spot treat the Bermuda with Round Up and kill it directly, and then replant St. Augustine in those areas. We do carry some professional round up products.
