B.T. Pawar

Introduction: Mango bacterial canker disease (MBCD) caused by Xanthomonas campestris pv. mangiferaeindicae (Xcmi) is one of the important diseases of mango affecting a number of commercial cultivars. The pathogen affects different plant parts like leaf, stem and fruit. Favorable environmental conditions cause severe loss to the crop.

Objective: Leaf extract of 37 plants were tested against Xcmi; out of them, leaf extract of Jasminum officinale L. gave promising results. Hence, fresh leaf extracts of J. officinale were screened for its antibacterial activity against 25 strains of Xcmi collected from different parts of Maharashtra.

Material & Method: The in vitro studies have been performed by using cup-plate method to examine the activity. Cup cavity filled with sterile distilled water was used as control in all the experiments. All experiments were repeated for four times (Experiment A, B, C & D).

Result: The maximum activity was recorded against Xcmi.21 (Mean activity zone – 21.94 mm) followed by Xcmi.10 (Mean activity zone – 21.67 mm) and comparatively minimum activity was recorded against Xcmi.14 (Mean activity zone – 20.27 mm).

Conclusion: The ultimate aim of the research work was to develop economically and technically viable field formulations for the farmers, which will be Bio-ecologically compatible for management of plant bacterial diseases.
