There is no cure for the disease, but the best approach to stop its spread is to simply not move citrus plants. Citrus plants should not be shipped across state lines. If plants are bought online, consumers should make sure the plant is not from an area that is quarantined for either Citrus Greening Disease or Asian Citrus Psyllids.
Many common plants can host the Asian Citrus Psyllid, such as oranges, lemons, limes and grapefruit. However, citrus plants infected by the citrus greening bacteria may not show symptoms for years following infection. Initial symptoms frequently include the appearance of yellow shoots on a tree. The most characteristic symptoms of citrus greening are a blotchy leaf mottle and vein yellowing that develop on leaves attached to shoots showing the overall yellow appearance. As the bacteria move within the tree, the entire canopy progressively develops a yellow color.
