INFORMATIVE ABSTRACT - Recently, the scientific community is increasingly questioning the use of synthetic chemical pesticides in plant disease management, as their impact on human health and the environment are coming to surface. Given the fact that some synthetic chemical pesticides, which were constantly used to control the soil borne phytopathogenic microorganisms, have been already banned by strict regulations, alternative compounds are needed to be used in soil fumigation.
The aim of this study is to test Lysobacter capsici AZ78 for its potential to produce volatile organic compounds (VOCs), which may contribute to the bioactivity against soilborne plant pathogens. There have been done some analysis and experiments with Lysobacter genus based on additional cultivation and by the combination of GC-MS measurements with the scope of revealing the identity of the VOCs.
Some VOCs have been selected as presumable bioactive compounds. As result, each of these was able to suppress the growth of the pathogens under investigation. 
This study highlights the possible future implementation of pyrazine derivatives in the control of soil borne plant diseases and further support the biocontrol potential of L. capsici AZ78.
