If not, what product would you recommend?
Tthe Grass Out Max is specifically designed to kill any and all grasses it is sprayed on and ONLY kill grasses. This would not be a product you would want to use over a sod lawn and instead you would want to go with a product that is selective in either a pre or post emergent form. Because poa annua and and fescue are so closely related, there are few products that will kill the poa annua without also harming the fescue. The only one we are currently aware of is called Prograss. Your other options would be to either spot-treat with a Roundup-type product and then reseed with the fescue in those areas, or you can use a preemergent like Prodiamine 65 WDG in the fall to prevent the poa from growing in the first place.
