Antagonistic Strain <i>Bacillus amyloliquefaciens</i> XZ34-1 for Controlling <i>Bipolaris sorokiniana</i> and Promoting Growth in Wheat

Common root rot, caused by <i>Bipolaris sorokiniana</i>, is one of the most prevalent diseases of wheat and has led to major declines in wheat yield and quality worldwide. Here, strain XZ34-1 was isolated from soil and identified as <i>Bacillus amyloliquefaciens</i> based on...
