Can I use Katana Turf Herbicide on kentucky bluegrass to kill poa?

Answer:

Katana Turf Herbicide states that cool season grasses such as Kentucky are sensative to this product. If you lawn is already senstive, it is best to not apply.  Since poa annua and cool season grasses are so closely related, there are no real products to remove it that would not also harm the desirable cool season turfgrass.  Your only real  option would be to spot-treat with a Roundup-type product and then reseed with the desirable grass type in those areas. You can use a pre-emergent like Dimension 2EW in the spring, or Pendulum 2G in the fall if you are not overseeding to help prevent the poa from emerging.
