Myrtle Rust: Which Plants are NOT Affected?
Plants which are not in the Myrtaceae family and therefore not hosts of myrtle rust include:
- Citrus
- Stone fruit
- Pome fruit (eg. apples, pears)
- Nut trees
- Vegetables
- Legumes (eg. lupins, clover)
- Conifers
- Lilies
- Azaleas
- Camellias
- Roses
- Daisies
- Rhododendrons
- Orchids
- Ferns
- Grevilleas
- Wattles
- Banksias
- Crepe myrtle
- Hakeas
- Kangaroo paws
- Grasses
- Nasturtiums
- Hop bushes
However, these and other non-Myrtaceae plants may show similar symptoms due to infection by other rusts.
Myrtle rust attacks young leaves and stems and should not be confused with yellow-coloured lichens growing on tree trunks or branches. Unlike lichens, the fungal spores of a myrtle rust infection are powdery.
