Key Points

The study aims to optimize fermentation conditions and identify active substances for controlling Rhizoctonia solani in potatoes.
Investigated fermentation conditions for Bacillus velezensis HZ33
Identified active substances with biocontrol potential
Assessed the effectiveness of marihysin B against pathogens.
Marihysin B was identified as the most active constituent of B. velezensis HZ33
Demonstrated strong biocontrol potential against Rhizoctonia solani
