Abstract/Contents:"Field trials were conducted in 2009 and 2010 to investigate the effects of metsulfuron-containing herbicides on tall fescue (Lolium arundinacea Shreb.) growth, seedhead production, and yield. Each year, various rates of metsulfuron, metsulfuron plus aminopyralid, metsulfuron plus 2,4-D plus dicamba, metsulfuron plus chlorsulfuron, and 2,4-D plus picloram were applied to a weed-free tall fescue hay field in the early spring vegetative stage, late spring boot stage, and in a late summer dormant stage of growth. In response to these herbicide treatments and application timings, tall fescue was harvested in early-June and mid-September of each year, according to a typical tall fescue hay harvest schedule followed in Missouri. Tall fescue height and seedhead production in response to each treatment and application timing were also determined prior to the summer hay harvest. When applied at the early spring vegetative timing, all metsulfuron-containing herbicides reduced tall fescue height by 13 to 41%, tall fescue seedhead production by 14 to 61%, and tall fescue summer forage yields by 18 to 72%. When applied at the late spring boot stage application timing, all metsulfuron-containing herbicides reduced tall fescue height by 24 to 50%, tall fescue seedhead production by 52 to 87%, and tall fescue summer forage yields by 8 to 40%. However, by the time of the fall harvests in both years, tall fescue had recovered from either spring application timing of metsulfuron-containing herbicides and yields were similar to the untreated control. Late summer applications of metsulfuron-containing herbicides also did not reduce yields of tall fescue compared to the untreated control by the fall harvest in either year. Results of this research indicate that early spring vegetative stage applications of metsulfuron-containing herbicides are likely to cause lower reductions in tall fescue seedheads but higher reductions in tall fescue yield than late spring boot stage applications, and that late summer applications of these herbicides do not reduce yields of tall fescue in the fall."
