Relating to or caused by Fusarium, a genus of fungi that commonly infects plants.
From 'Fusarium' (a fungal genus name from Latin 'fusus' meaning spindle, due to the spindle-shaped spores) plus the adjective suffix '-al.'
Fusarial infections have destroyed entire crop seasons—they're one reason farmers rotate crops, because these fungi can hide in soil for years waiting to attack again.
