TAILIEUCHUNG - Status of Rhizome and Pseudostem wet rot diseases of banana

Rhizome rot and pseudostem rot diseases of banana are caused by bacterial pathogens mainly of Pectobacterium carotovorum or Dickeya chrysanthemi individually or together and D. paradisiaca respectively. The bacterial rot diseases are reported to cause 40-70% incidence in severely infected fields and their occurrence has been reported worldwide. Diagnosis of the disease is based on presence of the characteristic symptoms such as brown rotting in rhizome and foul odor in advance stages in case of rhizome rot while wet brown rotting on pseudostem in initial stage followed by breakage of pseudostem from the point of wet rot in later stage for pseudostem wet rot. The pathogens are characterized by morphology, gram staining, biochemical and molecular bases. Management of the diseases is focused by use of chemicals, cultural practices and beneficial microbes. | 2019 8 5 764-771 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 05 2019 Journal homepage http Review Article https Status of Rhizome and Pseudostem Wet Rot Diseases of Banana M.

Introduction Banana is the major fruit crop grown mainly in tropical and subtropical continents. The cultivation of the crop is mainly affected by biotic factors. Among the biotic factors Fusarium wilt bacterial wilt caused by Ralstonia or Xanthomonas and soft rot or rhizome rot caused by Pectobacterium or Dickeya are the major ones which affect the crop. Fusarium wilt disease is distributed worldwide including India and considerable studies on molecular characterization and management practices
