Pythium vexans is a plant pathogen and it causes canker, damping-off and rot disease in many economically important crops including rubber trees, potato and sugar cane. It belongs to the group oomycetes which was originally classified among thefungi, due to its morphological and functional similarities. They are now classifed as protists based on modern insights on phylogentic relationship with photosynthetic organisms such as brown algae and diatoms.
