Evaluation of biocontrol properties of Streptomyces spp. isolates against phytopathogenic fungi Colletotrichum gloeosporioides and Microcyclus ulei [PDF]

open access: yesAfrican Journal of Microbiology Research, 2017
South American Leaf Blight (SALB) of the rubber tree, caused by Microcyclus ulei and foliar anthracnose caused by Colletotrichum gloeosporioides, are diseases that adversely affect rubber cultivation in America. Both diseases have a significant economic impact on this agricultural subsector. The aim of the present study was to evaluate the potential as

Disturbios histológicos causados por Microcyclus ulei y el complejo Colletotrichum spp. en caucho (Hevea brasiliensis) [PDF]

open access: yesSumma Phytopathologica, 2020
RESUMEN Las dos enfermedades más limitantes para el cultivo del caucho en Colombia son el Mal Suramericano de las hojas, ocasionado por Microcyclus ulei y la antracnosis, por Colletotrichum spp. Estos patógenos afectan los tejidos foliares, que bajo condiciones favorables pueden llegar a ocasionar la defoliación total de los árboles.

Physiological characteristics of Microcyclus ulei (P. Henn.) V.ARX. – a fungal pathogen of the cyanogenic host Hevea brasiliensis

open access: yesJournal of Applied Botany and Food Quality, 2012
The ascomycete Microcyclus ulei causes premature leaf shedding of the rubber tree, Hevea brasiliensis. During the development of this biotrophic fungus in the tissues of infected leaves HCN is liberated from the lesions.
