| Abstract: | Citrus canker disease caused by Xanthomonas campestris pv, citri is reported on lime in the present study for the first time in United Arab Emirates. The disease was found only on lime in 32 orchards out of 4456 citrus orchards inspected during 1984–85. The citrus canker organism in U.A.E. has a host range similar to “A” strain. Copper hydroxide was significantly superior to all other treatments in decreasing the incidence of citrus canker disease that developed on inoculated lime seedlings. Streptocycline, Kasumin, copper oxychloride and Bordeaux mixture were not effective in reducing the incidence of the disease. |
