Symptoms of M. palmivorus on salacca fruit would be obvious (Lestari 2005; Sukewijaya et al. 2009). Early infection is characterised by the appearance of white or pink mycelium growing over the surface of developing fruit bunches (Pinitpaitoon 2003). As the infection progresses, the fruit skin becomes black and soft, followed by brown wet rot on the flesh that is clearly defined from the healthy tissue (Pinitpaitoon 2003)
