South American leaf blight of Hevea brasiliensis: culture of Microcyclus ulei

Transactions of the British Mycological Society, 1978
Microcyclus ulei (P. Henn.) Arx was isolated by depositing fresh conidia on plain agar and then transferring it to potato sucrose agar. Dried rubber leaf extract stimulated growth, but some brands of agar inhibited growth and sporulation. Two morphological strains occurred amongst field isolations. The free sporulating strain appeared to be associated

Cyanogenesis of Hevea brasiliensis during Infection with Microcyclus ulei¹⁾

Journal of Phytopathology, 1986
AbstractEight Hevea species have been shown to be cyanogenic.They all liberated HCN following mechanical tissue injury. Infection of Hevea leaves with conidia of the plant pathogen Microcyclus ulei leads to a large reduction of hydrocyanic acid potential, while only small amounts of HCN are set free from the leaves into the atmosphere.

Genetic mapping and QTL analysis of Microcyclus ulei resistance in rubber tree (Hevea spp.)

2006
South American Leaf Blight (SALB), due to the fungus Microcyclus ulei, is potentially the major phytosanitary threat for rubber tree (Hevea brasiliensis) cultivation all around the world. After fifty years of breeding efforts, attempts to create resistant cultivars failed, the selected resistances being each time rapidly overcome by the fungus.

SALB : study of host-parasite relations between Hevea and Microcyclus ulei

1994
A cette date, aucune méthode de lutte totalement efficace n'existe contre la maladie sud américaine des feuilles d'hévéa (SALB). Des génotypes résistants ont seulement été sélectionnés. Cette communication donne l'état des travaux conduits sur les essais génétiques en Guyane Française et au Brésil après une étude sur la variabilité du pouvoir pathogène
