Abstract


In this study, phages active against S. marcescens, causative agent of onion decay, were isolated from plant material. One virus isolate was shown to accumulate in high titers and was denoted as phage S. This bacteriophage exhibited a hexagonal head and tail and was attributed to Myoviridae family. It was shown the ability of bacteriophage S to suppress the development of bacteriosis on geranium plants. Investigated virus isolate also inhibited rooting of onion scales. This work focused on a biological control approach to use bacteriophages for reducing bacterial pathogen populations and disease severity on plants.
