Approximately 16 year old lemon tree, gets ample water and ample sunlight (Scottsdale, AZ) - used to yeld amazing amount of fruit last few years. This year looks like it is shriveling up, the fruit is green and dry. Anyone that has some knowledge on this?

I hope you get an answer. I had an orange tree that did much the same thing last year...?

I have the same thing going on with my lemon...though in my case it could just be old age and light frost. There is a disease called "citrus greening" that has about wiped out the Florida citrus crops and is spreading west. I also got a notice that the city was spraying citrus in my neighborhood for some kind of physillid that was killing citrus trees, but I don't know if they are related to the greening, so I'd like to hear the answer to this myself.

The physillids do carry a disease that kills citrus.
Better call your local co-op or USDA.
They'll want to come check your tree.
They don't mess around. So far they have kept the physillids from getting a foothold in SanJoaquin valley.🕵️
👍👍
Anything i say, could be misrepresented, or wrong.

This is the best link I've found for info http://ipm.ucanr.edu/PMG/PESTN... If you want pictures there are lots of other sites...just type in Citrus Physillid
