Alabama Extension’s recommendations include products by active ingredients and labeled use rates for the primary diseases of turfgrass. Before using an insecticide, it is important to properly identify the pest. Alabama Extension has information describing the identification, biology, and management of many of the important pests of turfgrass. If an insecticide is needed, read the labeled instructions even if you have previously used the product. There have been changes in insecticide labeling recently, especially related to location and timing.

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.

Foliar lesions have raised, concentric circles on the underside of the leaf. Lesions frequently are surrounded by a water-soaked margin and a yellow halo. The middle of the lesion (on underside of leaf) has a corky texture. Fruit lesions consist of concentric circles. On some varieties these circles are raised and have a rough texture; on other varieties the concentric circles are relatively flat. Citrus canker has not been found in Alabama to date. If citrus canker is suspected, contact your local diagnostic lab.
