Pectobacterium chrysanthemi specific sequence and application thereof in detecting soft rot of konjak

The invention relates to the technical field of gene kit detection, and discloses a pectobacterium chrysanthemi specific sequence and application thereof in detection of amorphophallus konjac soft rot. Aiming at the characteristic that the amorphophallus soft rot pathogenic bacteria in Hubei province are mainly pectobacterium chrysanthemi (P.ch), a PCR (Polymerase Chain Reaction) specific primer of the pathogenic bacteria is designed, the specific detection kit is prepared, and the kit can be used for rapidly and effectively detecting whether the soil and the seed amorphophallus carry the pathogenic bacteria or not, and can be used for rapidly and effectively detecting whether the soil and the seed amorphophallus carry the pathogenic bacteria or not. And an effective and rapid means can be provided for monitoring, prevention and control of the soft rot disease of the konjak in Hubei province and detection of seed konjak.
