First report of black rot of Colocasia esculenta caused by Ceratocystis fimbriata in Brazil
Fitopatologia Brasileira 30 (1), 88-89
Abstract: Ceratocystis fimbriata was found sporulating in gray to black discolored areas on edible corms of Colocasia esculenta found in supermarkets in the states of São Paulo, Rio de Janeiro, Bahia, Rondônia and the Distrito Federal. In most cases the corms were grown in the state of São Paulo. The black rot appeared to occur post-harvest. Sequences of rDNA indicated that the Colocasia sp. isolates belong to the Latin American clade of the C. fimbriata complex, but the isolates were more aggressive than isolates from Ficus carica and Mangifera indica, in pseudopetioles of C. esculenta.
