The biocontrol of potato dry rot by microorganisms and bioactive substances: A review

Dry rot caused by Fusarium spp . is a devastating disease of potato, which occurs frequently around the world and causes significant economic losses. Chemical fungicides are the main strategy for dry rot prevention and control, but their intensive and long-term use can easily lead to fungal resistance, toxic residues, and environmental pollution, etc. Herein, safe and sustainable biological control is gradually becoming the hotspot and has a broad application prospect. Microorganisms and bioactive substances should be the important elements of biocontrol, which can inhibit the growth of Fusarium or induce potato resistance to resist dry rot. This review focuses on the pathogenic fungi, biocontrol microorganisms, bioactive substances and their biocontrol mechanisms of potato dry rot, in order to provide a theoretical basis for further research and application on biological control of the disease. • The information of Fusarium species causing potato dry rot are summarized. • The effective biocontrol microorganisms and active substances are listed. • The bioagents' mechanisms of controlling disease are diverse. • Bioagents play important role in controlling plant disease eco-friendly. • The commercial application of bioagents is worthy of attention.
