Citrus canker: Symptoms, causes, management and its control measures

Abstract

Citrus fruits of industrial interest include lemons, oranges, mandarins, grapefruits, clementines, limes and other commercially minor ones. A huge amount of agricultural waste is generated yearly all over the globe by citrus fruit industry. The wastes from these productions may be, however, of great nutritional and economic value for their chemical composition, due to their abundance of diverse functional compounds. Citrus canker, caused by the bacterium Xanthomonas citri subsp. citri, affects the leaves, twigs and fruit of citrus plants causing the leaves to drop and unripe fruit to fall to the ground. All types of citrus are affected by the disease.
