[Scpg] Can Anyone Help: I have Curly Leaf Disease on my Tangerine Tree

[Owen Dell]

You may have citrus leafminer, which has been very widespread the past  
few years. It's an insect, so fungicides wouldn't be effective against  
it. There is a good article on IPM for citrus leafminer at the UC  
Davis IPM website: http://www.ipm.ucdavis.edu/PMG/PESTNOTES/ 
pn74137.html. Have a look at the photo there and see if it looks like  
your problem. If it's leafminer you'll see hollowed-out areas inside  
of the leaves and they will sometimes be completely emptied of tissue,  
leaving only the semi-transparent cutin layer on the top and bottom.

Good luck!
Owen
