Abstract： Ginger blast is a bacterial soil-borne disease caused by Ralstonia pseudomallei，which is a serious threat to the yield and quality of Kerry ginger， a national Geographical Indicator product. In this experiment，we explored the effect of bagging cultivation on incidence blast disease and yield of ginger in the field. The results showed that the bagging cultivation method can not only effectively reduce the incidence of ginger blast in the field，but also improve the production of ginger. The incidence of ginger blast in different growth periods of ginger was 3.75% ， 26.25% and 32.5% ，and prevention and control effect was 56.25% ， 37.76% and 59.44% ，respectively. The yield increased by 10.59% compared with the conventional cultivation method. The effect bagging cultivation with bactericides application showed that ethylicin， tetramycin and kasugamycin were relatively effective in control of ginger blast. At35d after application，the control effect could reach 80.77% ， 65.38% and 63.27% ，respectively. The results of this study provide a new program and agent selection for the green prevention and control of ginger blast.
