- Worldwide distribution. On sugarcane, banana, pineapple, cocoa, coconut, sweetpotato, and others. Important as a wound fungus.
- A disease of sugarcane setts.
- Fungus enters cut ends, turning tissues red and then black with a pineapple smell. Buds and roots fail, plants dieback or are stunted with low sugar content.
- Spread by spores in wind, by insects, and by run-off water.
- Cultural control: use healthy setts from mature plants, at least 3-nodes long; drainage; use varieties that sprout rapidly; treat setts with hot water (51°C for 30 mins.); collect and burn trash after harvest.
- Chemical control: treat setts with carbendazim, if economic.
