Common Tree Diseases in Australia

Myrtle Rust

A serious fungal disease affecting plants in the Myrtaceae family (eucalypts, lilly pilly, bottlebrush). Symptoms include bright yellow spores on young leaves and shoots, deformation of new growth, dieback and in severe cases, tree death.

Phytophthora Dieback (Root Rot)

Caused by soil-borne pathogens, dieback affects roots, preventing trees from taking up water and nutrients. It impacts hundreds of native species, particularly jarrah, banksia and grass trees, and can rapidly kill large stands of vegetation.

Anthracnose

This fungal disease attacks leaves, flowers, and fruit, causing dark lesions, dieback and premature leaf drop. It commonly affects shade trees and ornamental species.

Powdery Mildew

Powdery mildew is a common fungal issue in gardens and landscapes, appearing as a white powdery growth on leaves and stems. It weakens trees and shrubs by reducing photosynthesis.

Canker Diseases

Fungal cankers cause sunken, discoloured areas on bark, eventually girdling branches or trunks. These infections often occur after storm damage or stress.

Leaf Spot Diseases

Various fungi cause brown or black spots on leaves, which can spread quickly in warm, wet conditions. Severe outbreaks may defoliate trees.

  • Targeted Solutions – We use proven fungicides, soil treatments, pruning, and cultural practices tailored to each disease.
