“…Recently, the resistance mechanism in glyphosate-resistant horseweed was attributed to the rapid vacuolar sequestration of glyphosate via a tonoplast transporter [71]. Other researchers studying glyphosate-resistant horseweed imply the involvement of transporter genes and suggest that non-chemical control methods might be utilized to manage the spread of resistance of this problematic weed [72]. AV is a bioherbicide that has potential for the non-chemical management of some herbicide-resistant weeds such as C. canadensis.…”

The effects of the bioherbicidal activity of the fungal phytopathogen, Albifimbria verrucaria (AV), formerly Myrothecium verrucaria, on glyphosate-resistant and –susceptible Conyza canadensis (horseweed) were examined in greenhouse and field studies. Spray applications of mycelial formulations of AV infected both glyphosate-resistant and -susceptible C. canadensis plants at various growth stages. Young plants in the rosette leaf stage of growth were controlled more efficaciously than were older plants that had bolted or that were in the inflorescence stage; nevertheless, severe injury and mortality also occurred in mature plants. The results indicate that this bioherbicidal fungus can infect and control C. canadensis, thereby demonstrating the potential of this fungus as a bioherbicidal agent against this troublesome weed, which has become resistant to various herbicides.
