Abstract

Uptake and delivery of Erwinia amylovora-specific bacteriophages in plant tissues were studied in order to improve the efficacy of a phage-besed biocontrol method against the bacterial phytopathogen E. amylovora, which causes fire blight of pome fruits. An American (ΦEa104) and one of our own Hungarian phage isolates (H5K) were applied by two different methods on apple seedlings grown in perlite medium. Following phage application to the root zone, plant parts above ground level were assayed for phage titers. In case of spraying phages onto the surface of the stem and leaves the roots were examined for the presence of phages at various times. Both phage isolates were detectable in plant parts above ground level as well as in the roots, in most cases on the first sampling day after treatment. However, the titer of introduced phage suspensions measurably decreased, and after seven days of treatment we could not detect phages in any of the samples. Nevertheless, demonstration of the translocation ability of these phages could serve as a basis for further investigations that may promote the more efficient application of bacteriophages for the control of fire blight.
