Description
Summary:In modern agricultural environment, plants are facing a number of challenges including various kind of environmental stress and pathogen attacks. These plant pathogens include fungi, oomycetes, bacteria, nematodes and arthropods. Pathogens in the soil have a detrimental impact on the production, yield and quality of numerous crops across the world. Various parasites of plant aboveground components (leaves, stems) persist in soil at various phases of their life cycle. Thus, soil quality is much important for the survival of pathogen into it even if they do not infect the roots of plants. In most cases, plant pathogens are managed with chemicals, which pollute the environment and contribute to pathogen resistance. Biochar is a strategy for managing plant diseases caused by pathogens in the soil, through various mechanisms such as fungitoxic, nematotoxic effect of biochar, sorption of allelopathic and phytotoxic compounds that can harm the plant, induction of plant resistance, increase in activities and abundance of beneficial microorganisms, changes in soil quality such as nutrient availability and abiotic conditions and induction of plant resistance. A variety of biochar effects contribute to the control diseases caused by pathogens by altering root exudates, soil characteristics and nutrient availability, all of which impact antagonist microbial proliferation. The induction of systemic plant defenses in the roots by biochar to diminish plant pathogens as well as the activation of stress-hormone responses and changes in active oxygen species, are all signs of coordinated hormonal signaling inside the plant. This review gives a brief summary of the effects of biochar on the physical, chemical and biological properties of soil, as well as in the management of plant pathogens and future direction. This is the first review in the literature which focus on boosting the soil physico-chemical properties along with its potential effect on plant pathogens.
