As a substitute for methyl bromide, effects of allyl isothiocyanate (AITC) on nontarget microorganisms in soil are poorly understood. This study measured the half-life of AITC in the soil as well as its effects on the soil substrate-induced respiration (SIR) and on communities of soil bacteria and fungi. The results showed that AITC had a short half-life and a short-term inhibition of SIR; high-throughput sequencing analysis showed that AITC had less effect on bacterial than fungal communities. Fumigation reduced the diversity of soil bacteria temporarily, but stimulated the diversity of soil fungi in the long-term and significantly changed the structure of the fungal community. Following AITC fumigation there were significant increases in the relative abundance of probiotics such as Sphingomonas, Streptomyces, Hypocreales, Acremonium, Aspergillus, and Pseudallescheria that help to control plant diseases. Our study provided useful information for assessing the ecological safety of AITC.

异硫氰酸烯丙酯熏蒸处理对番茄土壤微生物多样性和群落结构的影响。
作为甲基溴的替代品，异硫氰酸烯丙酯（AITC）对土壤中非目标微生物的作用了解甚少。这项研究测量了AITC在土壤中的半衰期及其对土壤基质诱导的呼吸（SIR）以及对土壤细菌和真菌群落的影响。结果表明，AITC具有短的半衰期和对SIR的短期抑制作用。高通量测序分析表明，AITC对细菌的影响小于真菌群落。长期熏蒸减少了土壤细菌的多样性，但长期刺激了土壤真菌的多样性，并显着改变了真菌群落的结构。进行AITC熏蒸后，益生菌（如鞘氨醇单胞菌，链霉菌，降甲藻，顶孢菌，曲霉，和假单胞菌有助于控制植物病害。我们的研究为评估AITC的生态安全提供了有用的信息。
