This project has drawn together a team of experienced plant scientists and a network of industry agronomists to update and consolidate research information on the threat of abnormal vertical growth (AVG) in the macadamia industry.


It has been looking at the current impact of AVG and potential causes of the disorder – including the role of biotic agents in its development and spread – and will provide recommendations for future research required for management, predictors and diagnostics.
