ABSTRACTTeratosphaeria stem canker is one of the most important diseases to have emerged on non-native plantation-grown Eucalyptustrees cultivated globally. The study assessed the pathogenicity of two Teratosphaeriaspecies associated with Teratosphaeria stem canker and the susceptibility of Eucalyptus grandisand six commonly grown Eucalyptushybrids to these fungal species in Uganda. The inoculation trials indicated that Eucalyptusspecies and hybrids were susceptible to fungal pathogens used. A comparison of Eucalyptusspecies and hybrids for each fungal species showed that GC 540 and GC 796/2 are the most susceptible hybrids to T. zuluensisand T. gauchensisrespectively while hybrid clone GU 8 had a higher tolerance to both fungal species. GC 540 was also tolerant to T. gauchensiswhile F2 and GC 550 were tolerant to T. zuluensis. Eucalyptus grandissourced from Australia (F2) showed a higher tolerance than Eucalyptus grandisfrom South Africa (F1). The results further revealed that both Teratosphaeria zuluensisand Teratosphaeria gauchensisare pathogenic to Eucalyptusspecies and hybrids. The generated information indicates that there is an opportunity to sustainably manage Teratosphaeriastem canker disease if tolerant species are grown in areas with high disease impact. |
