The degradation of soil microbial diversity driven by agricultural intensification underscores the urgent need for sustainable alternatives. Bacillaceae strains associated with the wheat rhizosphere, identified as Bacillus velezensis ZAV-W70 and Priestia megaterium ZAV-W64, have been genetically and phenotypically characterized as possessing beneficial traits, including antimicrobial compound biosynthesis pathways and plant growth-promoting properties. To explore alternatives to chemical fungicides, we evaluated the effects of B. velezensis ZAV-W70 and P. megaterium ZAV-W64 in wheat field trials. ZAV-W70 alone achieved yields comparable to those obtained with chemical fungicide co-application and increased yield by 11.7% relative to the water-treated control. Seed treatment with P. megaterium ZAV-W64 combined with fungicide not only increased yield by 7% but also improved bread-making quality, evidenced by significant increases in total gluten content (10%) and alveograph W parameter (15%) compared to fungicide treatment alone.These findings support the potential of beneficial rhizobacteria to contribute to more sustainable wheat production systems.
