Mango malformation has become the most important global disease on mango. F usarium species previously associated with this disease include F . mangiferae , F . mexicanum , F . sterilihyphosum , F . proliferatum , F . subglutinans and F . tupiense . A few strains of F . proliferatum have been reported from M alaysia, but in this study, we report the results of more extensive sampling. The recovered strains were evaluated with morphology, mating tester strain cross‐fertility, amplified fragment length polymorphisms ( AFLP s), and partial DNA sequences of the genes encoding translation elongation factor 1‐α ( tef‐1α ) and β‐tubulin ( tub‐2 ). Amongst the 43 strains evaluated, three species were identified – F . proliferatum , F . mangiferae and F . subglutinans – with F . proliferatum being the most frequent (69%). None of the F usarium species that appear to originate in the A mericas were recovered in M alaysia, which suggests special measures may be warranted to keep these species from entering the country.
