Plant-parasitic nematodes wreak havoc on the yield and quality of crops worldwide. Damage from these pests is estimated to exceed US$100 billion annually but is likely higher due to misdiagnosis. Nematode damage may be catastrophic, but historically the solution has been damaging as well. Use of the synthetic nematicide methyl bromide (MBr) poses risks to the environment and to human health. Biofumigation, the use of plant material and naturally produced compounds to control pests, is an increasingly feasible method of pest management. The process acts through the growth or incorporation of plant material into the soil, that, over the course of its degradation, releases glucosinolates that break down into nematotoxic isothiocyanates. These secondary plant metabolites exist naturally in commonly grown plants, most of which belong to the Brassicaceae family. Research endeavors have increasingly explored the potential of biofumigation. The reaction of target pests, the selection of biofumigant, and ideal environments for efficacy continue to be evaluated. This review seeks to provide a cost and benefit assessment of the status of biofumigation for the control of plant-parasitic nematodes as an alternative to conventional methyl bromide usage.

植物寄生线虫对全世界农作物的产量和质量造成严重破坏。这些害虫每年造成的损失估计超过1000亿美元，但由于误诊而可能造成的损失更高。线虫的破坏可能是灾难性的，但历史上解决方案也一直具有破坏性。使用合成的杀线虫剂甲基溴（MBr）对环境和人类健康构成威胁。生物熏蒸，即使用植物材料和天然产生的化合物来控制害虫，是一种越来越可行的害虫管理方法。该过程通过植物材料的生长或掺入土壤而起作用，在其降解过程中，释放出芥子油苷，后者分解成对线毒的异硫氰酸盐。这些次生植物代谢产物天然存在于通常生长的植物中，其中大多数属于十字花科。研究工作越来越多地探索了生物熏蒸的潜力。继续评估目标害虫的反应，生物熏蒸剂的选择以及理想的功效环境。这项审查旨在提供成本和效益评估，以控制作为替代常规甲基溴用途的植物寄生线虫的生物熏蒸状况。
