The most characteristic symptom of HLB is blotchy mottling that appears asymmetrically on the leaf blade. Green islands may also occur; these are small, circular, dark green dots that contrast with the light yellow/green background. Foliar symptoms that resemble nutrient deficiencies may be present. A tree may exhibit yellow shoots or other nutrient deficiency symptoms on one or more branches randomly in the canopy. Fruit may be small and lopsided or ripen backward, with the stylar end remaining green as the fruit colors.

Management tips: Citrus greening has not been found in Alabama to date. If citrus greening is suspected, contact your local diagnostic lab.

Initial symptoms include vein yellowing followed by yellow foliage, poor growth, and shoot dieback. Advanced symptoms consist of leaf and fruit drop, trunk lesions, and tree death. Trunk lesions are found near the crown or below the soil line and may contain bark cracking and gumming.

Management tips: Use resistant rootstock (trifoliate orange). Plant the bud union at least 6 inches above the soil line. Do not overwater. Control ants around the base of the tree. Prevent mechanical injury to the trunk.
