Unfortunately, we are not aware of a product which is labeled to control actively growing grass burrs or sand burrs that is also safe to be applied to bahia. What we typically recommend is that you spot treat as much as much as possible with a nonselective product (such as Roundup QuikPro) and then replant with the bahia in those areas in a couple of weeks when the grass/sandburrs are gone. To prevent any future growth of these weeds, you can apply a pre-emergent (such as Dimension 2EW) in the fall and spring.
