Abstract : Treatment with hexaconazole, a systemic fungicide, reduced the Colonization Frequency percentage (CF %) of foliar fungal endophytes of Mangifera indica L. The CF % of the endophytes in treated leaves was low during the treatment; it gradually rose to reach near-control level during the post spray period. Although the species diversity of the endophyte assemblage of control and treated leaves did not vary significantly, the composition of the assemblage varied. A correspondence analysis showed that the fungicide treated leaves were colonized by a few endophytes that were absent in untreated leaves.
