Unfortunately, Japanese stiltgrass is not only extremely difficult to control with most chemicals, but it is also similar in plant structure to bermudagrass. This means if a product controls the stiltgrass, then it has the potential to damage, suppress or kill the bermudagrass that its sprayed on as well. This is the case with Acclaim Extra Selective Herbicide.
