In-vitro inhibiton of Pantoea ananatis by antagonistic bacteria

International Conference on Advances in Natural and Applied Sciences (ICANAS) -- APR 18-21, 2017 -- Antalya, TURKEY
Like most cultivated crops, onions (Allium cepa L.) are plagued by phytopathogenic bacteria. Although bacterial diseases of onion occur sporadically, they can cause loss of yield, in the range of a few percent up to 40%. Center rot of onion caused by Pantoea ananatis is the one of the major bacterial disease. Cultural methods and copper compounds often are recommended for control of bacterial diseases, but these are insufficient and the use of some chemicals has adverse effects. For these reasons, biological control is important manner for control of plant disease. In this study; it was researched that in-vitro inhibition effect of 271bacterial strains on P. ananatis in-vitro. Commercially available streptomycin, kanamycin and tetracycline disks were used as control. In consequence; three isolates show more or less inhibitory effect against P. ananatis.
