Sounds pretty dire, Sway. Have you tried the aspirin treatment? Got this tip from
@LariAnn a year or so ago. Crush 3 or 4 regular aspirin (not the coated ones or baby aspirin, the old white chalky ones 325mg.) and dissolve them in some water. It helps to heat up the water a bit, but it still takes a really long time for them to dissolve. Put the solution in a sprayer with a gallon of water and spray the plants.
I hope she chimes in on this, because I forget the details of how it works. I've been spraying my little citrus tree against greening disease, and I have hopes that it's helping.
In any case, if it's a disease that you can't do anything about why not just forge ahead regardless? Just keep the plants as healthy as possible and the strong ones will eventually survive. I know plants don't have an immune system like people do, but they can evolve different attributes that stand up to disease better, like thicker cell walls, for example. If you just throw out every plant that shows the first signs of a disease, you never advance the resistance process.
