How to treat marks on Eucalyptus leaves?

[BenB]

Hi everyone,

I hope you're all doing well.

I have a question regarding our eucalyptus tree. Over the past 4-5 months, we've noticed some unusual marks on the leaves. Can anyone help identify what disease this might be and suggest how we can treat it?

Thank you.

HI @BenB 

Have to agree with @MitchellMc. As the younger leaves look reasonable I would not be too concerned about the older leaves - they will drop as they age anyway so if it's a cultural problem (eg watering or some other similar cause) the rest of the tree will not be affected.

I'd be inclined to play the 'wait and see' game.
