Annual bluegrass has shown susceptibility to currently available preemergence herbicides such as oryzalin, pendimethalin, dithiopyr, prodiamine, or oxadiazon (Smith et al., 1986 Webster et al., 1986 Higgins et al., 1991 Lewis, 1991 McCarty, 1991 Coats, 1992 Lewis, 1994 Murphy and Johnson, 1995). However, these herbicides do not provide broadleaf control equal to the triazines. Although annual bluegrass control is often very good with these herbicides, there are usually some broadleaf weeds that are not controlled, such as lawn burweed and purple cudweed (Murphy and Johnson, 1995).
