PoaCure (methiozoline) is an experimental use permit herbicide that has high activity against annual bluegrass (Poa annua) on greens. Several tests are being conducted on creeping bentgrass greens at both low and high elevation locations in Arizona. The research objective is to determine if repeat fall applications differ from repeat spring applications for the elimination of annual bluegrass. Initial testing shows good creeping bentgrass tolerance and that perhaps a fall application program is more effective in annual bluegrass removal than a spring program.
