Brosnan 1 , Gregory K. Breeden 2 , John M. Zobel 3 , Aaron J. Patton 4 and Quincy D. Law 5 Continued reliance on chemical methods for annual bluegrass control has resulted in many populations evolving resistance to PRE and POST herbicides, particularly in warm-season turfgrass species such as zoysiagrass. Soil seedbank management is critically important when managing herbicide-resistant weeds. Fraise mowing (also spelled fraze, frase, fraize) is a new turfgrass cultivation practice designed to remove aboveground biomass while allowing turf to re- grow vegetatively. We hypothesized that this process would remove annual bluegrass seed and 1 Professor, Dept. of Plant Sciences.
