Overview

Laboratory tests show Bacillus subtilis and Bacillus velezensis decrease root rot symptoms in strawberry, indicating effective biocontrol agents.

Key Points

  • This research aims to evaluate the biocontrol efficacy of Bacillus strains against strawberry root rot.
  • Screened antagonistic bacterial strains from healthy strawberry plants and soils.
  • Performed morphological and biochemical identification alongside 16S rDNA analysis.
  • Evaluated antifungal activity of cell-free culture filtrates and volatile organic compounds against pathogens.
  • Inhibition of N. clavispora hyphal growth by Bacillus strains ranged from 63% to 73%.
  • Broad-spectrum inhibition of other phytopathogenic fungi was observed with rates between 50% and 79%.
  • Significant increase in superoxide dismutase and peroxidase levels in strawberry leaves was noted.
