Elm leaf beetle (pyrrhalta luteola)
The Elm Leaf Beetle (ELB) was discovered in Victoria around 1989 and is becoming increasingly more widespread. It has the potential to cause severe defoliation during the summer months which can weaken mature trees and possibly kill the tree. Elms that suffer from repeat attack are also more susceptible to other pests and disease.
Elm Beetles eat holes in the leaves while the larvae skeletonise the leaf leaving the veins and a thin film.
If you are concerned about your Elm there are ways to protect the longevity of it and prevent if from being affected. The best time for treatment is between August to October when the trees are in full leaf and we recommend treatment every 2 years.
We can provide the following:
- professional assessment
- trunk injection
