How does myrtle rust spread?
The myrtle rust fungus produces thousands of spores which are highly mobile. These spores spread rapidly through wind, human activity and animals. Common ways include:
- movement of infected or contaminated plant material
- animals such as bees, birds, bats and possums
- contaminated plant waste, timber and wood packaging
- contaminated equipment and tools used on or around plants
- contaminated clothing and shoes.
Rust pustules can mature to release spores in as little as 10 to 12 days. Spores can survive for up to three months in the environment.
