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 bioagents reduces application bactericides, which harmful humans and environment. However, mechanisms some bioagents, such fungi bacteria, not yet understood. This paper reviews current situation rot, biological controls, antagonistic their mechanisms, strategies future directions today’s agriculture. These include mycoparasitism, competition, rhizosphere colonisation, synthesis release metabolites. Bioagents increased defensive system plants by increasing antioxidants genes, superoxide dismutase, peroxidase (POD) catalase (CAT), eventually plant growth yield production.
