Title: What desease is this?
Post by: vitormesquita on June 01, 2015, 12:58 PM
Hi guys,
A couple weeks ago, my bonsai (cherry) started to have yellow spots in its leaves (see picture).

Do you know what that is about?  Is there any treatment?

Many thanks!

Best regards,

Vitor

Is there any insect damage on the tree?  How's the underside of those leaves look?

No damage at the tree structure, only the eaves - under the leave is full of yellow spots.

Only th leaves seems to be affected by it  :-[

One of the sucking insects.  No disease.

To me it looks like it might be rust or some other leaf spot disease.  But just a guess.
