“The bacteria is fatal to citrus trees and has decimated citrus groves in Florida and Texas. Now, California growers are holding the line to keep producing the vital crops. As temperatures rise, that gets more difficult.”
EDIT: the tail-end of Wikipedia’s entry points to a Citrus Grower article – seems that cover crops and healthy soil biology seem to help citrus trees weather the disease a lot better
Is this disease a problem in the EU and northern Africa as well?
from Wikipedia, it’s already extant in Middle East, North Africa, and Portugal – but the African strain is heat sensitive (won’t tolerate temperatures over 25°C)
