Recognising myrtle rust
Myrtle rust produces bright orange to yellow clumps of powdery spores or pustules. The appearance of these spores or pustules on foliage or twigs varies slightly, depending on the species of host plant, so expert identification is needed.
Anyone who finds what they suspect is myrtle rust should ring the Pest and Disease Information Service (PaDIS) on Freecall: 1800 084 881 to report the location. If possible take a photograph and email it to firstname.lastname@example.org.
Symptoms can also be reported through the MyPestGuide reporter app or by making an online report.
Do not take a sample to post to the Pest and Disease Information Service, because snipping off a piece of diseased plant could dislodge the spores and accelerate the local spread of myrtle rust.
