Danger

Citrus canker is a contagious disease caused by the bacteria Xanthomonas citri subsp. citri, which can affect all citrus species and cultivars. The disease presents as lesions or cankers at infection sites and severely impacts fruit quality and yield. Premature fruit drop can occur, along with defoliation, twig dieback and general tree decline. In severe cases, it can lead to tree death.
