RESUMO

ABSTRACT: The fungus Fusarium sacchari (E.J. Butler & Hafiz Kahn) W. Gams, was consistently isolated from infected malformed shoots and panicles of mango in the Cerrado Region of Central Brazil, from 1998 to 2000. Pathogenicity tests of the F. sacchari isolates were carried out on potted six month-old Tommy Atkins seedlings by introducting a PDA disk with fungal mycelium and conidia in a vertical slit at the tip. F. sacchari is almost completely restricted to shoot tissues in malformed trees. The levels of colonization are highest in malformed vegetative and floral shoots and are much lower in asymptomatic shoots. Treatment of mango malformation with fungicides is ineffective. The only viable control option is the removal and burning of the affected shoot tissue.
