Formation of Citrus Canker Lesions1

Citrus canker is a non-systemic bacterial disease that affects citrus trees in both the citrus nursery and in commercial plantings. Canker is easily spread from plant to plant. Early symptom detection will reduce plant-to-plant spread and minimize lesion development, resulting in fewer losses to citrus nursery stock. Maintaining disease-free plant materials is critical in supporting optimal production standards.
