the sigatoka disease complex of banana involves three related ascomycetous fungi viz., mycosphaerella fijiensis, m. musicola, and m. eumusae. due to rather similar symptoms on banana, similar teleomorph morphology and problems associated with growth and sporulation in culture, species identification based on classical methods is troublesome. the exact distribution of these three species and the...

Black leaf streak disease (BLSD) caused by Mycosphaerella fijiensisa an ascomycete fungus is the most important foliar ofbananas (Musa sp.). Losses due to this pathogen can exceed 50% in case of no resistant cultivars and effective treatments. This study aimed evaluate efficacy four biopesticides on severity fijiensis. It was conducted under natural infestation conditions industrial dessert ban...

Black Sigatoka Disease, also called Leaf Streak Disease (BLSD), is caused by the fungus Mycosphaerella fijiensis and arguably one of most important pathogens affecting banana plantain industries. Theoretical results on its dynamics are rare, even though theoretical descriptions epidemics plant diseases valuable steps toward their efficient management. In this paper, we propose a mathematical mo...

Yellow and black Sigatoka, caused by Mycosphaerella fijiensis M. musicola, respectively, are the most important worldwide foliar diseases of bananas. Disease control is heavily dependent on intensive fungicide sprays, which increase selection pressure for resistance in pathogen populations. The primary objective this study was to assess level spread quinone-outside inhibitors (QoI—strobilurin) ...

Black Leaf Streak Disease (BLSD) is the most restricting leaf disease to banana tree cultivation around world. In order control this disease, synthetic fungicides are extensively used. However, these products pose a real danger environmental pollution and health of applicators consumers. Faced with situation, alternative solutions must be considered overcome their systematic use. This study was...

High polyphenol and polysaccharide levels in plant tissues such as banana fruit and leaves constitute a significant challenge to the extraction of sufficient amounts of high-quality RNA required for cDNA library synthesis and molecular analysis. To determine their comparative effectiveness at eliminating polyphenols, polysaccharides and proteins, three protocols for RNA extraction from in vitro...

Landscape genetics, which combines population genetics, landscape ecology and spatial statistics, has emerged recently as a new discipline that can be used to assess how landscape features or environmental variables can influence gene flow and spatial genetic variation. We applied this approach to the invasive plant pathogenic fungus Mycosphaerella fijiensis, which causes black leaf streak dise...

The chemical management of the black leaf streak disease in banana caused by Mycosphaerella fijiensis (Morelet) requires numerous applications of fungicides per year. However this has led to fungicide resistance in the field. The present study evaluated the activities of six fungicides against the mycelial growth by determination of EC50 values of strains collected from fields with different fu...
