Purpose: The present study evaluates the antifungal activity of essential oils Curcuma longa and Eucalyptus globulus on strains Lasiodiplodia theobromae Pseudocercospora fijiensis in Kisangani region (DR Congo).
 Methods: were obtained after extraction by hydro distillation method. isolation L. was made from fragments mesocarp taken diseased cocoa, previously cut with a Scarpel then disinf...

ABSTRACT DNA fingerprinting has been used extensively to characterize populations of Mycosphaerella graminicola, the Septoria tritici blotch pathogen of wheat. The highly polymorphic DNA fingerprints of Mycosphaerella graminicola were assumed to reflect the action of transposable elements. However, there was no direct evidence to support that conclusion. To test the transposable element hypothe...

Species of Eucalyptus are widely planted as exotics in the tropics and Southern Hemisphere and to some extent in southern Europe, for timber and fibre production. Species of Mycosphaerella are commonly associated with leaves and twigs of Eucalyptus and can result in defoliation, dieback, and even tree death. In the present study, numerous isolates of Mycosphaerella species were collected from l...

Mycosphaerella punctiformis, the type species of the genus Mycosphaerella, is epitypified by material collected on Quercus robur in The Netherlands. The teleomorph is described in planta, and the Ramularia anamorph, for which the new name R. endophylla is proposed, and the Asteromella spermatial state are characterized in vitro. Sequence data of the nuclear ribosomal DNA are presented and analy...

Species of Mycosphaerella and their related anamorphs represent potentially serious foliar pathogens of Eucalyptus. The fungi treated in the present study were isolated from symptomatic Eucalyptus leaves collected in Thailand during June-October 2007. Species were initially identified based on morphological and cultural characteristics. Identifications were confirmed using comparisons of DNA se...
