Engineering soil fungal microbiome via plant debris triggered Fusarium wilt disease suppression

Promoting the development of suppressive soils is as a promising strategy to protect plants against soil-borne diseases in a sustainable and viable manner. The use of crop rotation and the incorporation of plant debris into the soil are known to alleviate the stress imposed by soil pathogens through systematic changes in soil physicochemical and biological properties. Relatively little is known about the extent to which specific soil amendments of plant debris trigger the development of plant-protective microbiomes. Here, we investigated how the incorporation of pineapple residues in soils highly infested with the banana Fusarium wilt disease (Foc4) alleviates the pathogen pressure via systematic changes in soil microbiomes.
