New eucalypt pests and diseases: what is the risk and how should we respond?
By Ian Hood & Lindsay Bulman, Scion, December 2018.
Eucalypts have been grown in plantations in New Zealand since the late 1800s. Throughout this period they have been subject to incursions of exotic insect pests and fungal pathogens. A number of these organisms have impacted severely on eucalypt health and productivity leading to the elimination of some species from plantation forestry. Further introductions will undoubtedly occur, and an up to date assessment of the biosecurity risk to eucalypts is needed in order to minimise uncertainty and aid decision-making when a new insect or pathogen incursion occurs.
