摘要：
The present invention provides methods for development of a virulent bacteriophage-based treatment for the control of plant diseases caused by Xylella fastidiosa. The invention further provides methods of isolating and propagating bacteriophage virulent to X. fastidiosa in a Xanthomonas bacterial host and for treating or reducing symptoms of X. fastidiosa infection in a plant. The invention further provides methods of isolating and propagating bacteriophage virulent to Xanthomonas axonopodis pv. citri and for treating or reducing symptoms of Xanthomonas axonopodis pv. citri infection in a plant. In particular, the present invention relates to a plant disease biocontrol composition comprising a combination/phage cocktail of both Xfas100 type phages which have a morphology typical of Siphoviridae and Xfas300 phage types which have a morphology typical of Podoviridae. Both phage types are virulent to Xylella fastidiosa and Xanthomonas species.
