My mature avocado tree is dropping all it's leaves

[Or1on]

Another disease to be on the alert for.

The Hawaii Dept of Ag confirmed that my friend's tree is infested with the relatively new Avocado Lace Bug Disease.  You may not see the bug but the colony of eggs (tiny black specks) on the underside of the leaves is visible.  Leaves begin to brown on the edges and start dropping off.

After looking at this thread and this post by taropatch I am noticing almost every avocado tree in the Puna area being attacked by these lace bugs.  Just look under the leaves and you can see evidence of them.
