Abstract
Citrus canker is a disease caused by the bacterium Xanthomonas axonopodis PV. Citri, which infects all forms of citrus fruits among them includes sweet oranges. The disease is believed to have its origin in Asia from where it spread to all other tropical and sub-tropical citrus growing regions, it does not infect arid citrus growing areas. The study was conducted in Gweri sub county in late July where data was collected using questionnaires from farmers across the three parishes where sweet orange is grown in quite large amounts, the study involved face-to-face interaction and making observations to identify signs of the disease by conducting a random simple zig-zag format of sampling on the lines of orange plants, data obtained was analyzed to calculate the prevalence using the formula in the methodology section. It was found that canker disease was more prevalent in Valencia (26.2%) and least in Washington (7.3%), only 20% of the participants were using the effective control measures, this study, therefore, was aimed at finding out the prevalence per variety, and control of citrus canker disease by farmers of sweet oranges at Gweri sub-county.
