In Colombia, it is the most important disease attacking cocoa crops and the traditional strategies for control have generated side results as strengthening in genetic resistance of strains in some regions. Nowadays, this disease is present in almost all Latin American countries producers of cocoa beans, exhibiting high adaptation to diverse environments. gileri in the mesic forests of north-west South America.įrosty pod rot disease of cocoa plants is caused by the basiodiomycete Moniliophthora roreri. gileri is the vestigial progenitor of the frosty pod rot pathogen of cocoa, with a host range and distribution restricted to T. gileri proved to be noninfective to cocoa pods when compared with positive control strains isolated from T. In addition, in a field inoculation experiment, an isolate from T. gileri and these meiospores are interpreted to represent a much modified probasidium. roreri, meiosis is shown to occur within the dispersive and infective spore stage of var.

cacao) on the basis of spore morphology, incompatibility and nucleotide sequence data. The latter was collected on Theobroma gileri, an endemic tree of submontane forests in north-west Ecuador, and can be distinguished from Ecuadorian and Peruvian isolates from cocoa (T.

Morphological, cytological and molecular evidence is presented which confirms that the frosty pod rot pathogen of cocoa, formerly classified as the mitosporic fungus Moniliophthora roreri (Deuteromycota), belongs to the hymenomycetous genus Crinipellis (Basidiomycota) and that two varieties should now be recognized: Crinipellis roreri var.
