Antagonistic bioagent mechanisms of controlling potato soft rot

Bacterial antagonists are effective as an alternative to synthetic bactericides in the control of potato soft rot. 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.

Automated summary

Explored the application and mechanisms of bioagents in controlling potato soft rot, and highlighted their advantages over synthetic bactericides in terms of human and environmental safety. Revealed that bioagents enhance plant defense system and promote plant growth and yield through various mechanisms.
