Erasing the Past: A New Identity for the Damoclean Pathogen Causing South American Leaf Blight of Rubber

BACKGROUND South American leaf blight (SALB) of rubber has been the main constraint to production in its neotropical centre of origin since commercial plantations were first established. The fungal causal agent was identified and described more than a century ago but its precise placement within the Ascomycota still remains uncertain. Indeed, such is the ambiguity surrounding the pathogen that ...

Genetic parameter estimations of three traits used to evaluate South American leaf blight (SALB) in rubber tree

Attack severity, sporulation intensity and stromata density are three symptoms of South American Leaf Blight caused by Microcyclus ulei (P. Henn.) v. Arx. evaluated in the field on one to three year-old rubber tree [Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell.-Arg.]. This genetic study under epidemiologic conditions of the Michelin plantation, Itiquira, State of Mato Grosso Brazil, used ...

Neofusicoccum ribis Associated with Leaf Blight on Rubber (Hevea brasiliensis) in Peninsular Malaysia

Hevea brasiliensis is a natural source of rubber and an important plantation tree species in Malaysia. Leaf blight disease caused by Fusicoccum substantially reduces the growth and performance of H. brasiliensis. The aim of this study was to use a combination of both morphological characteristics and molecular data to clarify the taxonomic position of the fungus associated with leaf blight dise...

Integrated control of garlic leaf blight caused by Stemphylium solani in China Garlic leaf blight control

Leaf blight caused by Stemphylium solani is a major fungal disease of garlic (Allium sativum) in central China where it has caused severe crop losses during the winter growing season from the end of autumn to the middle of spring. Epidemiology, cultivar resistance, and chemical controls were investigated during the 2006 to 2008 growing seasons in Dangyang County to improve disease control metho...
