中文摘要:采用熏蒸剂进行土壤消毒可有效控制设施作物及高附加值作物的土传有害生物,其中熏蒸效果突出的熏蒸剂溴甲烷由于会破坏臭氧层而被禁用,导致土传有害生物熏蒸治理过程中缺乏高效稳定的熏蒸产品。二甲基二硫是一种新型熏蒸剂,对有害线虫具有高活性,可兼治部分土传病原菌及杂草。广谱、安全和高效等优点使其成为最有推广应用前景的溴甲烷替代药剂,或将改善国内杀线虫熏蒸剂缺乏的局面。该文系统综述了国内外关于二甲基二硫对土传有害生物的防控活性、作用机制和降解、散发逃逸、扩散分布及残留等环境行为,以及对土壤养分、微生物及非靶标生物等方面的影响,以期为二甲基二硫的开发及推广应用提供参考。

Abstract:Using fumigants for soil disinfection can effectively control soil-borne pests in facility agriculture and high-value crops. Methyl bromide, the most effective soil fumigant, was banned due to ozone destruction, resulting in significant problem of lacking efficient and stable pesticides for soilborne pest control. Dimethyl disulfide(DMDS) is a new fumigant with good control efficacy on harmful nematodes, some soil-borne pathogens, and weeds. The characteristics of broad-spectrum, safety,and high efficiency make it one of the most promising methyl bromide alternatives, which may make up for the lack of nematicidal fumigants in China. In this paper, the research progresses in DMDS activities and mechanism of action against soil-borne pests, the environmental behaviors like degradation, emission, diffusion distribution and residue of DMDS, and the effects of DMDS on soil nutrients, microorganisms and non-target organisms are reviewed, with a view to providing a reference for the development, popularization and application of DMDS.
