Biochar mediated control of soil-borne phytopathogens

Biochar is a solid product obtained by heating biomass or organic waste in the total or partial absence of oxygen and used as a soil amendment. Several beneficial effects of biochar on soil chemical, physical, and biological properties and plant health and development are widely known. Biochar amendment has also been repeatedly discussed for its disease suppressive properties. However, the underlying mechanisms of such effects are highly complex and mostly unknown. It can be assumed that the modification of plant root exudate composition, changes in soil microbial and biochemical properties, and the induction of systematic plant defense mechanisms due to biochar amendments are crucial factors impacting pathogen suppression. More in-depth studies are needed to understand specific interactions of plant-pathogen systems with different types of biochar, which will help achieve maximum benefits of biochar amendments to protect plants from various soil-borne pathogens. In this review, we highlight the potential of biochar for the control of soil-borne plant diseases, especially the interactions with plant pathogenic fungi, under different environmental conditions. We concluded that soil amendment with biochar is a promising strategy for integrated pathogen and pest management.
