A ‘new’ disease identified in Australia by Dr Thomas in the early 1900’s. Not commonly found however an infected plant rarely survives. This example was photographed over 40 years ago.


Thought to be a complex of viruses it is said to be spread by insects such as Aphids. Other thoughts relate to chemical use. Unfortunately few cases are ever seen so hard to have tested to find out more.

Symptoms vary from stunted growth through to curling of the leaves. Affected leaves seem brittle and will fall from the plant with slightest touch. Occurs mostly on the new growth which appears in spring.
