Update on the occurrence of Xanthomonas campestris pv. citri in Saudi Arabia

It was reported at the workshop on "Citrus Pest Problems and their Control in the Near East Region" that Xanthomonas campestris pv. citri (EPPO A1 quarantine pest) has spread further in Saudi Arabia. The disease was first found in 1983 in the Southwestern Region of the country, but has spread in the following years to the Western Region. Efforts to limit its spread have resulted in only limited success. Experiments to control the disease by applications of a spray mixture of the antibiotic Kasugamycin and copper oxychloride proved unsuccessful. Quarantine regulations within the country to prevent the spread to some important citrus growing regions have been imposed.
