15 de abr. de 2013 · The fungicides effectively controlled the disease caused by the species of Mycosphaerella present in the trial (M. cryptica and M. nubilosa). Even at low levels of infection by the Mycosphaerella spp. (less than 10% leaf area affected), the unsprayed trees had significantly poorer growth, with height increment reduced by 13% and diameter increment by 4%.

1 de may. de 2006 · INTRODUCTION. Eucalyptus spp. are widely planted in the tropics and Southern Hemisphere, providing important sources of structural timber and fibre. Fungal diseases have, however, had a negative impact on their cultivation in many parts of the world (Wingfield et al. 2001).Mycosphaerella leaf blotch (MLB) was one of the first diseases to seriously damage plantations of Eucalyptus outside their ...
27 de nov. de 2008 · TAXONOMIC HISTORY. Sphaerella cryptica and S. nubilosa were originally described from diseased Eucalyptus leaves collected near Melbourne, Australia (Cooke, 1891).These two ascomycetous fungi were to become two of the most well‐recognized and important Eucalyptus leaf pathogens. Their placement in Sphaerella was incorrect and, after examination of the type material, S. cryptica and S ...
1 de ene. de 2007 · Mycosphaerella, one of the largest genera of ascomycetes, encompasses several thousand species and has anamorphs residing in more than 30 form genera. Although previous phylogenetic studies based on the ITS rDNA locus supported the monophyly of the genus, DNA sequence data derived from the LSU gene distinguish several clades and families in what has hitherto been considered to represent the ...
