Biocontrol potential and mechanism of an endophytic Bacillus subtilis strain KS1 against fire blight.

Key Points

• The aim is to evaluate the biocontrol potential of an endophytic Bacillus subtilis strain KS1 against fire blight.
• Evaluated the impact of Bacillus subtilis strain KS1 on fire blight in pear crops
• Assessed mechanisms of biocontrol through laboratory and field tests
• Bacillus subtilis strain KS1 significantly reduced fire blight incidence (p<0.05)
• Positive effects on plant growth and health observed in treated crops
