Conclusion: The control efficiency after 1 day of the 800~1000times of 10 billion spores/ml empedobacter brevis GXW15-4 pesticide is between 77.35% to 82.83%;the control efficiency after 3 days is between 90.40% to 93.29%; the control efficiency after 7 days is between 77.49% to 80.58%. The control efficiency after 3 days is the highest.The statistical analysis showed that the control efficiency of 3 diluted concentrations is no significant difference.we recommend to use 800~1000 times of empedobacter brevis GXW15-4 pesticide,that is per hectare using 750 ~937.5ml. Pay attention to spary on opposite of the leaves . Whether sparying equably is the key to affect the control efficiency.
