BACKGROUND: Citrus canker, a bacterial disease caused by Xanthomonas citri subsp. citri (Xcc), is one of the major threats to the citrus industry. Inorganic copper (Cu) formulations such as Bordeaux mixture and Kocide 3000 are currently used to control citrus canker
however, they are poorly water-soluble and have negligible plant transport, making the systemic treatment of citrus canker difficult. RESULTS: This study synthesized Cu CONCLUSION: This study provides a new, eco-friendly and more efficient option for citrus canker control. © 2025 Society of Chemical Industry.
