Abstract: Weeds are responsible for significant losses in agriculture. Synthetic herbicides have adverse environmental effects. The utilization of fungal phytotoxins as an alternative to weed control is still limited. This study evaluated the herbicidal potential of CFCF and culture extracts of Aspergillus isolate against Parthenium. Formulation of culture extracts with adjuvants was also assessed for herbicidal potential by bioassays. CFCF of Czapek-Dox medium supplemented with casein was observed to be more phytotoxic in comparison to CFCF of Czapek-Dox medium. Formulation of culture extract of Cz with adjuvant tween 80 exhibited maximum phytotoxicity, while maximum phytotoxicity of culture extract of Cz+C was observed when it was formulated with mustard oil.
