Abstract: Soft rot disease occurred frequently has become the bottleneck for restricting the development of konjac planting industry. The research progress of the identification, the infection pathways, the prevention and control of soft rot pathogens was summarized. We can screen and create the resource for konjac of the high quality and disease resistance (tolerance), so we can obtain resistance materials of soft rot disease. We can mine new bioactive substances or new genes against pathogen of the soft rot by the metagenomic library constructed of the rhizosphere soil microbial of konjac, so we can obtain the new resources and strategies for ecological prevention the soft rot disease. We can study the change of soil microbial community for konjac rhizosphere by the theory of the rhizosphere microecological balance, so we can reduce or eliminate the soft rot disease of konjac by the modified for the soil biological activity.
