Abstract:

The most important diseases of eucalyptus in the plantations are leaf and shoot blight caused by Cryptosporiopsis eucalypti and associated with defoliation, dieback and mortality of eucalyptus trees. Disease causes major losses in nurseries and plantations resulting in failure of planting material and reduction of biomass production or loss of germplasm. Pathogenicity test using seedlings have shown that the fungus can infect stems as well as leaves. Isolated organism was identified as Cryptosporiopsis eucalypti based on the ITS sequencing and comparing with the NCBI database with more than 98 per cent similarity. 100 clones of eucalyptus were screened in glass house condition. 13 clones showed moderately resistant reaction with disease severity index of 1. 54 clones showed susceptible reaction with disease severity index of 2 and remaining 33 clones showed highly susceptible reaction with disease severity index of 3.
