Velocity Herbicide for Poa annua Control in Winter Turf

摘要

Sequential applications of 45 gm AI/A tended to show more Poa annua suppression than 30 + 30 gm AI/A or 60 + 30 gm AI/A. Velocity applied twice at a 1 week interval showed slightly greater Poa annua suppression than when applications were made 2 or 3 weeks apart. Poa annua control was marginally acceptable at one of two sites when sequential applications were made at a 1 week interval.
