The plant pathogenic Xanthomonas oryzae pv. oryzae (shortly XOO) bacteria causing bacterial leaf blight (BLB) is one of the most destructive disease of rice. The bacterial infection is able to cause up to 50% crop loss. XOO is a quarantine species on EPPO (European and Mediterranean Plant Protection Organization) A2 list in Europe. There is no effective pesticide, which would be suitable for the treatment of the disease caused by XOO.

The cooperation of Enviroinvest Co. (Pécs) and Biological Research Center, Hungarian Academy of Science (Szeged) aimed the development of an environmental friendly pesticide agent, which could be suitable against XOO. The active agent of the pesticide are that kind of special bacteriophages (viruses), which are able to destroy only the targeted (and host) bacterial species, so the usage of these bacteriophages has a minimal effect to the natural microflora and bacterial community.

All together 9 bacteriophages (3 phages from samples collected in Vietnam, 6 phages from samples collected in Philippines) were isolated during the project cooperating with International Rice Research Institute. However all the isolated bacteriophages show high genetically similarities, they are able to effectively destroy XOO bacterial strains, which was confirmed laboratory and green house trials. Furthermore, there was low level of resistance detected during the research project, so these bacteriophages could be suitable for the effective agent against XOO.

During the research project a sonicator and a fluorometer machine were purchased, which were needed for the whole genome sequencing of the bacteriophages.
