Loved it for taking out nimblewill and patches of bent grass in my KBG lawn. Didn't even have to reseed or sod. White is annoying.
Turned a clients yard white before a renovation. Thankfully we warned client and they didn't freak out.
Supposed to work on Poa. Like someone said be ready to make many, timely apps!
Good specialty product but not for general, blanket apps.
