Anaerobic soil disinfection (ASD) has been identified as an alternative soil-borne pathogen control strategy to chemical fumigation. ASD involves the application of an easily liable carbon source followed by irrigation to field capacity and maintenance of an anaerobic condition for a certain period. A literature search undertaken on ASD found that more than 50 comprehensive research projects have been conducted since its first discovery in 2000. Most of these studies were conducted in the USA and in the Netherlands. Though the exact mechanism of ASD in pathogen control is unknown, promising results have been reported against a wide range of pathogens such as fungi, nematodes, protists, and oomycetes. However, it is interesting to note that, except for a few studies, ASD research in the developing world and in the tropical countries has lagged behind. Nevertheless, with soil quality depletion, reduction in arable lands, and exponential population growth, a drastic change to the current agricultural practices should be adapted since yield gain has reached a plateau for major staple crops. Under such circumstances, we identified the gaps and the potentials of ASD in tropical agricultural systems and proposed promising biodegradable materials.
厌氧土壤消毒（ASD）已被确定为一种替代化学熏蒸的土壤传播病原体控制策略。ASD包括施用易分解的碳源，随后灌溉至田间持水量，并在一定时期内维持厌氧条件。对ASD进行的文献检索发现，自2000年首次发现以来，已经开展了50多个综合研究项目。这些研究大多在美国和荷兰进行。尽管ASD控制病原体的确切机制尚不清楚，但已报道了针对多种病原体（如真菌、线虫、原生生物和卵菌）的良好结果。然而，有趣的是，除了少数研究外，发展中国家和热带国家的ASD研究滞后。尽管如此，随着土壤质量下降、耕地减少和人口呈指数增长，由于主要主食作物的产量增长已达到平稳期，应大幅改变当前的农业做法。在这种情况下，我们确定了热带农业系统中ASD的差距和潜力，并提出了有前景的可生物降解材料。
