Nathan from Ma writes
Roundup QuikPRO - 5 x 1.5 oz. packs is a non-selective herbicide, so it will kill any grass or weeds it is applied to including poa annua. If you are targeting poa annua in a lawn you may want to go with a selective herbicide labeled for its control in warm season grass lawn types, or if you have a cool season grass lawn such as fescue or bluegrass you will need to carefully spot treat with a product like this.
