BIOSECURITY ALERT – MYRTLE RUST – Austropuccinia psidii

WHAT’S AT RISK, WHERE DO I LOOK?
Myrtle rust only effects plants from the Myrtacae plant family. This includes some of New Zealand’s most iconic indigenous plants – rata, pohutukawa, manuka, kanuka and ramarama – as well as exotic myrtles like feijoa, guava and eucalypts. It attacks new leaves on many plants and mature leaves on others. It can suppress flowering and seed development on some host plants. Repeated infections can kill the plant.
