Different types of composts have gained attention for their potential applications in sustainable agriculture and for their inhibitory effects against plant pathogens. This study investigates the suppressive effects of lavender compost extracts on common plant and soil pathogens and evaluates the composts' microbial composition. Pathogenic fungi, including Sclerotinia sclerotiorum, Fusarium oxysporum, Botrytis cinerea, and Alternaria alternata, were subjected to in vitro assays with varying concentrations of the extracts. The results revealed inhibitory effects due to compost microbiota; several fungal genera (Aspergillus, Penicillium, Trichoderma) and bacteria were detected. Microbial analysis of the compost extracts indicated the presence of beneficial microorganisms, such as Trichoderma spp., which may contribute to plant pathogen suppression. These findings suggest that lavender compost extracts can be a natural, eco-friendly alternative for managing plant pathogens and promoting sustainable agricultural practices. Further studies regarding the mechanisms underlying their biocontrol properties are recommended.
