Huanglongbing (HLB) (June 2022)

Australia is increasing its biosecurity for an incurable plant disease that has crippled citrus-producing regions around the world and is posing an ever-growing threat to our local citrus industry. Huanglongbing (Chinese for yellow shoot disease), or HLB is a lethal, rapidly spreading, bacterial disease of citrus. Currently, it is not found in Australia, however HLB is endemic in many of our northern neighbours. This Nursery Paper provides information on the host range of the pathogen and describes symptoms in the leaf, fruit and whole tree in affected plants. Diagnosis, prevention, quarantine, eradication and management are also considered.
