Integrated management of citrus canker caused by Xanthomonas axonopodis pv. citri (Hasse) in acid lime (Citrus auruntifolia)

Citrus canker is an important disease caused by the bacterium Xanthomonas axonopodis pv citri affecting acid lime orchards worldwide. Studies were conducted on integrated management of citrus canker at College of Agriculture, University of Agricultural Sciences, Raichur, Karnataka, India by through sanitation and pruning followed by different combinations of copper fungicides, bactericides, ISR chemical, botanicals and bioagent. The results of the experiment revealed that, crop sanitation followed by spraying of streptomycin sulphate (500 ppm) + COC (3g L⁻¹) was found effective with per cent disease index (PDI) of 30 and it was on par with sanitation followed by Bordeaux mixture (1%) spray followed by bacterinashak (0.5g L⁻¹) and Pseudomonas fluorescens (5g L⁻¹) spray with PDI of 32.17.
