Hello everyone,

I have noticed for some time now a white powder/saltish like deposit under pretty much all leaves, except young ones. Do you have any idea?
Thank you in advance,
Pierre.

They look like little spores or eggs to me.

I'd consider that you could simply wipe these all clean with a cloth if there aren't too many.
I can't imagine they would be good for your tree and I can't imagine a tragic end to simply cleaning them off.

If there is too many i'd try just hosing them all off maybe?

Thank you Boics,
All leaves are like that...? Doesn't seem to bother the tree the slightest but it does bother me!
It does rub off very easily indeed.
Will keep you updated.
Cheers

Looks like a pest to me. I'ld be getting rid of it asap
