Abstract: Weeds are the major menace to agriculture, which greatly impact crop growth and development, resulting in economic yield loss or crop failures. Therefore, it is indispensable to take up appropriate weed management practices to prevent the effects of weeds on crops. Chemical herbicides have immense potential for effective control of weeds, but, in the long run, the persistent nature of herbicides adversely affects the soil microbes and also that terrestrial and aquatic ecosystems. Bioherbicides are products derived from plant extracts, allelochemicals or microbes and their secondary metabolites with weed-suppressing abilities. Most microbial bioherbicides are based on fungi and its active ingredients, which successfully control weeds with different mode of actions. Moreover, the toxins or secondary metabolites the fungi produce also possess herbicidal properties. So, exploring the fungal pathogens and their toxins for managing weeds seems to be a feasible and eco-friendly way for the management of weeds. There is a wider scope for utilizing fungi and their secondary metabolites as mycoherbicides, which have the potential to replace hazardous chemical herbicides in the near future. This review article mainly emphasizes the scope of mycoherbicides and explores the fungal secondary metabolites for eco-friendly weed control.
