The subject invention concerns a novel bioherbicide and its use to control weeds known as nutsedges (Cyperus Spp). The novel fungus, Dactylaria higginsii (Luttrell) M.B. Ellis is pathogenic to purple nutsedge, yellow nutsedge, annual sedge, globe sedge, rice flatsedge, and Cyperus brevifolius. These sedges cause major losses in different crops and turf. Accordingly, the fungus of the subject invention is an important advance in the control of these noxious weeds.
