researchers have created a mathematical model that shows how
citrus greening is transmitted within an infected tree — an
important step toward helping scientists understand the
devastating disease. The model, published this month by the
journal Proceedings of the National Academy of Sciences,
revealed that once a tree is infected, insecticides to control
the pests that spread the disease may not be enough to halt the
disease’s progression in the tree, and instead may only slow its
spread within the tree. Removal of obviously diseased new
growth, called flush, or shoots, is not a solution either. The
model shows that even without showing symptoms, many shoots may
already be infected so that infection of other pa
