Gordons Ornamec 170 Grass Herbicide is a grass killer and will harm Kentucky Bluegrass if sprayed. When applied to grasses it can only be on Tall Fescue and Zoyiagrass. Using a pre-emergent like Dimension before the brome germinates would be a better option for control. If you need to control it post emergent, spot treating with a glyphosate based product and reseeding the KGB would be best.
