Perspectives on microbial community changes produced by Hermitia illucens frass and their impact on soil suppression against Fusarium oxysporum f. sp. lactucae.

ABSTRACT:

Background

Organic soil amendments rich in chitin have demonstrated significant potential promoting suppressive soils. Suppressive soils inhibit the growth and activity of soilborne pathogens, being a sustainable alternative to chemical fumigation. The aim of this study was to determine the ability of frass produced from black soldier fly larva (BSFL), a novel chitin-rich soil amendment, and other amendments enriched in chitin to promote suppressive soils against Fusarium oxysporum f. sp. lactucae (Fol) and to assess the role of the microbial community on suppressiveness. BSFL frass, compost, chitin and a mixture of compost and chitin were mixed with soil. Some soil mixes were incubated for 4 months to promote further changes in the microbial community structure. Then, incubated an
