Plant resistance to disease: Using biochar to inhibit harmful microbes and absorb nutrients

Phytosanitary concerns are part of today's agricultural environment. The use of chemicals to treat plant diseases is both a source of pollution and allows pathogens to become resistant. Additionally, it can improve the chemical, physical, and biological properties of soil. Therefore, the soil environment is more conducive to healthy plant growth. By improving the chemical, physical, and biological attributes of soil, biochar can enhance plant resistance. Agricultural success has been attributed to biochar's acidic pH, which promotes beneficial soil microorganisms and increases soil nutrients; it is also porous, which provides a home and protects soil microorganisms. By improving soil properties, biochar becomes even more effective at controlling pathogens. The article also discusses the benefits of biochar for managing pathogens in agricultural soils. In addition, we examine several research papers that discuss the use of biochar as a method of combating soil-related pathogens and plant diseases. Biochar can be used to combat soil-borne diseases and other conditions. •Biochar can also enhance plant health in addition to increasing crop yield.•Pyrolysis of biomass leads to the production of biochar.•Conversion of waste biomass using the physical, chemical, and biological technique for biochar production.•Biochar exhibits systemic response to bacteria, fungi, and virus infection.•Engineering biochar increases the efficacy of biochar against plant disease.
