The typical spot symptoms on fruit would decrease the production and merchandise of tomato in the heavy rain of June and July; therefore, the key period for disease control is after rainy season. Quick identification on pathogen was using PCR. 1476bp band was amplified by primer P3、P4of bacterial speck. By using primer CMM5、CMM6 for bacterial canker, 614bp fragment was amplified. These PCR tests provided important foundation for pathogen identification and disease diagnoses. Using primer RST65 and RST69 for bacterial spot, expected 420bp band was not amplified.
