Citrus Greening (Huanglongbing): A devastating bacterial disease with no known cure. Symptoms include yellow, blotchy leaves, stunted growth, and bitter, misshapen fruit. Infected trees must be removed.

Introduce beneficial insects like ladybugs and lacewings.
Use insecticidal soaps and horticultural oils for severe infestations. Treatment of Fungal Diseases:
Prune out affected branches and ensure good air circulation within the tree. Apply copper-based fungicides according to label instructions.
