Since 1981, I started research on comprehensive prevention and treatment of epidemic disease, and the prevention and treatment methods have achieved remarkable results in large-scale production. First, the identification of bad bacteria disease Bakana disease mainly occurs in the seedling stage to heading, grain can also be victims, the typical symptoms of leggy.
