In order to improve the quality of flue-cured tobacco,to provide a scientific basis for flue-cured tobacco plant disease biologi-cal control.The application of research was conducted to study effects of DMP+Bacillus megaterium on the production of flue-cured to-bacco in Yunnan Shizong county.The result shows that the application of DMP+Bacillus megaterium at flue-cured tobacco seedling stage can better improve the main agronomic characters than that of only DMP ,and the application of 0.2 g per plant can significantly improve the emergence rate,seedling and the optimum.By tracking survey on flue-cured field phase,the treatment can promote the growth of tobacco plants,among which applying DMP +Bacillus megaterium (0.2 g/plant)at the seedling stage and applying DMP (0.5 g/plant)at the flue-cured period were highly enhanced the five agronomic traits index:plant height,stem diameter,leaf number, maximum leaf length and maximum leaf width and performed best on TMV,tobacco blank shank and tobacco brown spot,with 64.17%,58.38% and 62.72% effect respectively compared with that of blank control.
