Production and optimization of bioherbicide with improved phytotoxicity by regenerated fusant strain of <i>Fusarium oxysporum</i> and <i>Fusarium incarnatum-equiseti</i>

Abstract

(65%) when compared to parent strains (58-65%, 32 -38% and 45.5-48.5%), respectively. Highest phytotoxic activities of the metabolites were recorded at 14 days of fermentation, and pH 6.0 and 6.5 for parent and fusant strains, respectively. The study revealed the significance of the protoplast fusion technique in improving the efficacy of bioherbicides from fungal strains for effective management of weeds.
