Armillaria root rot of citrus trees


Armillaria root rot is caused by various species of the fungal pathogen Armillaria, predominantly Armillaria luteobubalina.

The disease is most common in coastal NSW citrus orchards, where clearing of native eucalypt forests has left infected roots, but has been known to occur occasionally in inland orchards.

All commonly grown citrus cultivars are susceptible.
