Inhibitory Effect of Ectomycorrhizal Fungi on Bacteria Wilt of Eucalyptus

  • Received Date: 1998-04-13
  • Field trials including nursery experiment were established in this research to determine the efficacy of antagonism of 8 ectomycorrhizal fungal isolates of 4 species to bacterial wilt pathogen. The results showed that these ectomycorrhizal fungi were effective in controlling the occurrence and development of this disease.The disease rates of mycorrhizal seedlings were reduced by 40.00%~72.78% in a nursery and 20.0%~38.9% in the field compared to those of uninoculated ones. Furthermore,the height and basal diameters growth of trees in the trials were enhanced by 11.67% to 59.7% respectively due to the contribution of inoculated fungi used in the experiments.There is a great potential to apply the techniques of mycorrhizal fungal inoculation to preventing the occurrence and development of the bacterial wilt in Eucalyptus plantations.

Abstract: Field trials including nursery experiment were established in this research to determine the efficacy of antagonism of 8 ectomycorrhizal fungal isolates of 4 species to bacterial wilt pathogen. The results showed that these ectomycorrhizal fungi were effective in controlling the occurrence and development of this disease.The disease rates of mycorrhizal seedlings were reduced by 40.00%~72.78% in a nursery and 20.0%~38.9% in the field compared to those of uninoculated ones. Furthermore,the height and basal diameters growth of trees in the trials were enhanced by 11.67% to 59.7% respectively due to the contribution of inoculated fungi used in the experiments.There is a great potential to apply the techniques of mycorrhizal fungal inoculation to preventing the occurrence and development of the bacterial wilt in Eucalyptus plantations.
