The use of bioagents reduces the application of synthetic bactericides, which are harmful to humans and the environment. However, the mechanisms of some bioagents, such as some fungi and bacteria, are not yet understood. This paper reviews the current situation of potato soft rot, biological controls, antagonistic bioagents and their mechanisms, application strategies and future directions in today's agriculture. These mechanisms include mycoparasitism, competition, rhizosphere colonisation, synthesis and release of metabolites. Bioagents increased the defensive system of plants by increasing the antioxidants genes, such as superoxide dismutase, peroxidase (POD) and catalase (CAT), and eventually increased the plant growth and yield production. bacteria; biological control; phytopathogens; disease; induced systemic resistance 10.17221/166/2020-PPS https://pps.agriculturejournals.cz/artkey/pps-202201-0002.php https://pps.agriculturejournals.cz/artkey/pps-202201-0002.php continuing 58 1 18 30 2021 12122580 periodical academic journal
