The BC sterilized dan developed by our institute was used as contact sprays and TC as seed disinfectant to control rice bacterial leaf streak. The result of net room test showed that BC sterilized dan and TC could control more than 90% of the stubble in seedling stage. In the field trials in Chenghai City, seed disinfection and seedling application could delay the onset of disease more than 7 days, the disease rate and disease index were lower than the control and field application, at the same time, the loss of about 10% of the yield can be recovered , Saving 90% of prevention and control costs, is a highly efficient, labor-saving, provincial medicine prevention and treatment methods.
