| Abstract/Contents: | "Several field observations and limited research have confirmed that sulfonylurea herbicides commonly used in warm-season turf can laterally relocate via turf equipment and injure neighboring cool-season grasses. This phenomenon is referred to as 'tracking' among turf managers and often occurs when mowers traverse treated areas and adjacent creeping bentgrass putting greens, fairways, and tee boxes while foliage is wet with dew. Tracked flazasulfuron and metsulfuron at 9 and 42 g/ha, respectively, caused little injury to creeping bentgrass. Flazasulfuron at 26 and 53 g/ha, and foramsulfuron at 28 g ai/ha tracked while dew was present 20 h after treatment (HAT) resulted in the most noticeable creeping bentgrass injury when tracked. Flazasulfuron at higher rates and foramsulfuron tracked 20 HAT on dew-covered turf reduced turf color compared to nontracked turf. When the mower traversed dry turf at 6 HAT and wet turf at 68 HAT, turf color was reduced less than wet turf tracked 20 HAT. Length of track and creeping bentgrass injury decreased with flazasulfuron rate. When using flazasulfuron at rates between 9 and 53 g/ha, a 1.5- and 4.5-m border, respectively, around creeping bentgrass would eliminate most injury from tracked herbicide." |
