Will this kill off Perennial Rye grass in a mostly Kentucky Bluegrass (KBG) lawn without damaging the KBG? Cool Season Zone 6b. If not, is there anything that will? My front lawn is less than 2k sqft and don't want to burn it all down because there's still good KBG. I overseeded Rye into my lawn in Fall 2022 and hate how it looks.
Grass Out Max is a non selective grass killer, meaning it will kill your KGB as well. Unfortunately there is not a selective product that will remove one cool season lawn from another. The only approach will be to spot treat the rye grass with a non-selective such as Roundup QuikPRO - 5 x 1.5 oz. packs
