    Abstract:
    In times of increasing societal pressure to reduce the application of pesticides on crops, demands for environmentally friendly replacements have intensified. In the case of late blight, a devastating potato plant disease, the historically most widely known plant destroyer has been the oomycete Phytophthora infestans. To date, the most important strategy for control of this pathogen has been the frequent application of fungicides. Due to the aforementioned necessity to move away from traditional chemical treatments, many studies have focused on finding alternative ecofriendly biocontrol systems. In general, due to the different modes of actions (i.e. antagonistic effects or induction of plant defence mechanisms), the use of microorganisms as biological control agents has a definite potential. Amongst them, several species of lactic acid bacteria have been recognised as producers of bioactive metabolites which are functional against a broad spectrum of undesirable microorganisms, such as fungi, oomycetes and other bacteria. Thus, they may represent an interesting tool for the development of novel concepts in pest management. This review describes the present situation of late blight disease and summarises current literature regarding the biocontrol of the phytopathogen P. infestans using antagonistic microorganisms.
