Soilborne pathogens are a constant threat to vegetable crops across Virginia. Fumigants and fungicides are the most common methods used to manage soilborne pathogens in bedding vegetables; however, the phase-out of methyl bromide and the high cost and toxicity of other available fumigants have created a need for additional economic and environmentally friendly options to treat soilborne plant pathogens. Anaerobic soil disinfestation (ASD) is a technique that was developed independently in Japan and the Netherlands in the early 2000’s to manage soilborne diseases. This publication discusses how ASD works, efficacy, carbon sources, how to implement ASD on-farm, and impacts on the soil microbiome.
