Anaerobic soil disinfestation (ASD), a biological alternative to soil fumigation, has been shown to control a wide range of soil-borne pathogens and nematodes in numerous crop production systems across Japan, The Netherlands and the US. A brief review of the status to the science behind ASD and its application for commercial settings is discussed for each country.
Future work needs to focus on how to optimize the technique (in terms of carbon source used, temperature and degree of anaerobiosis attained) to control specific sets of pathogens, and to better which mechanism(s) are responsible for disease control in different situations.
The role of observed microbial community shifts as a result of ASD in immediate disease control and long term disease suppression needs to be more fully explored.
Further reductions in the costs of ASD compared to fumigant use will help increase adoption of the technique which is currently limited by cost and uncertainty about its effectiveness at controlling different pathogens across a range of environments.
