Cool-Season Turfgrass Reseeding Intervals for Sulfosulfuron
D. W. Lycan and S. E. Hart
Turf managers may wish to reseed turfgrass species into areas where weeds have been eliminated by sulfosulfuron treatments. Field studies were conducted in 2002 and 2003 in New Jersey to determine when creeping bentgrass, Kentucky bluegrass, and perennial ryegrass can be safely reseeded after a sulfosulfuron application. The study suggests that perennial ryegrass can be safely reseeded two weeks after a sulfosulfuron application, whereas creeping bentgrass and Kentucky bluegrass may require two to four weeks before reseeding can occur.
