Phylogeny, Morphology, Distribution, and Pathogenicity of Seven Calonectria Species from Leaf-Blighted Eucalyptus in HaiNan Island, China

Plant Disease, 2023
Leaf blight caused by Calonectria species constrains Eucalyptus trees in China. Calonectria leaf disease on Eucalyptus in China was first reported in HaiNan Island in 1985. No systematic investigation of Calonectria species associated with diseased Eucalyptus in HaiNan has been performed.

Pathogenic variation in Cylindrocladium quinqueseptatum causing leaf blight of Eucalyptus¹

European Journal of Forest Pathology, 1991
AbstractA wide range of pathogenic variation was observed among the five isolates of Cylindrocladium quinqueseptatum leaf blight (CLB) which could be distinguished as different physiologic strains on 11 differential provenances of Eucalyptus. Susceptibility ranking of different provenances to five isolates also differed significantly indicating ...

Calonectria eucalyptorum sp. nov., a new leaf blight pathogen of Eucalyptus from India

International Microbiology
In this study, Calonectria eucalyptorum sp. nov. is described from the blighted leaves of Eucalyptus in India using morphological and multi-locus phylogenetic analyses. The new species belongs to the Calonectria cylindrospora species complex, and its unique microscopic features and DNA sequence information enable clear separation from the 12 currently ...

Two Newly Reported Leaf Pathogens ofEucalyptus grandisin South Africa

South African Forestry Journal, 1991
Pilidium acerinum and Ceuthospora lauri are newly reported pathogens from Eucalyptus grandis leaves in South Africa. Symptoms occurred on leaves of lower branches towards the end of winter. Although occurring together on the same lesion, both fungi were individually patlogenic, Inoculation studies showed that P. acerinum was the more virulent pathogen.

LAMP Assay to Detect Elsinoë necatrix, an Important Eucalyptus Shoot and Leaf Pathogen

Plant Disease
Eucalyptus scab and shoot malformation caused by Elsinoë necatrix is an emerging disease and a serious threat to the global commercial forestry industry. The disease was first discovered in North Sumatra, Indonesia, and now requires a simple and effective method for early pathogen detection.

Sporothrix eucalypti (sp. nov.), a shoot and leaf pathogen ofEucalyptus in South Africa

Mycopathologia, 1993
A species of Sporothrix was consistently isolated from leaf spots and serious shoot infections on a clone of Eucalyptus grandis in Northern Natal, South Africa. The fungus was morphologically distinct from other species in the genus and is consequently described as a new taxon, S. eucalypti.

Eucalyptus citriodora leaf extract‐mediated biosynthesis of silver nanoparticles: broad antimicrobial spectrum and mechanisms of action against hospital‐acquired pathogens

APMIS, 2019
Pathogen resistance to conventional antibiotics has become a serious clinical and public health problem, making the development of an alternative mean a very urgent issue. Recently, biosynthesis of silver nanoparticles (Ag NP s) was successfully accomplished in the presence of
