Evaluation of Bacillus velezensis Biocontrol Potential against Fusarium Fungi on Winter Wheat

Fungi of the genus Fusarium are economically significant pathogens in most wheat-growing regions worldwide. The biocontrol agents Bacillus velezensis BZR 336 g and 517 were tested for growth inhibition F. graminearum 4. results demonstrated that strains capable deforming destroying hyphae. modified bioautography technique showed produce iturin A surfactin, which probably explains mechanism pathogen inhibition. Furthermore, lipopeptides detected identified two samples by HPLC-HRMS. Compounds such as surfactin their isomers homologues found both samples. An experiment on an artificial infectious background a climatic chamber established biological effectiveness is close to chemical references. Cultivation plants with B. likely reduce stress load. efficacy up 45.0% was determined bioagents field trials, while yield 7.9 t/ha. use provides environmentally friendly approach control rots wheat, reduction pesticide load, hence quality harvest.
