Cyclamen rohlfsianum, Antibacterial, Xanthomonas.Abstract
Xanthomonas is one of the most important genera that leads to severe losses in many agricultural crops, the exertion to control is constrained to the utilisation of industrial pesticides, which have brought human and environmental health problems, and the emergence of resistant strains. This work was carried out to evaluate the activity of the aqueous extracts of leaves and tubers of Cyclamen rohlfsianum at concentrations (50, 100, 200 and 400) mg/ml against (Xanthomonas campestris pv. vesicatoria and Xanthomonas axonopodis pv. eucalyptus) by a sensitivity test by a disk diffusion method. The results showed that Cyclamen rohlfsianum extracts have good inhibitory activity against tested bacteria, the tubers extracts are more efficient than leaf extracts, a concentration of 400mg/ml was the most effective to control bacteria. Xanthomonas axonopodis pv. eucalyptus was the most sensitive to aqueous extracts. The study concluded that Cyclamen rohlfsianum showed promising antibacterial activity and effective control programs for the control of diseases caused by Xanthomonas.
