Since 1949, summed up the experience of the masses and years of experiments, summed up a comprehensive approach to prevention and control, which has played a good role in the protection of high-yield tobacco. In order to fully understand the occurrence and prevalence of black shank and the relationship between environmental conditions, the pathogen, host, rainfall and relative humidity and temperature were interrelated, and the results showed that temperature, rainfall, age and pathogens The quantity and the change of mycology are closely related to the occurrence and prevalence of tobacco black shank disease.
