This study evaluates the influence of crop seasons, cultivation regions, and traditional agricultural practices on the occurrence of and in the rice chain in the Mekong Delta, Vietnam. A survey on pre- and post-harvest practices was performed from 2017 to 2019 in parallel with sampling. Results showed that (36.3%) and (10%) were predominantly present throughout the rice chain. These fungi frequently occurred in winter-spring and autumn-winter crops in Can Tho paddy. Especially, appeared both on the field and during transportation (50-100%), while presented at all stages (10-33%). The occurrence of reduced 70-27% after drying, depended on the seasons, compared to field and transportation stages and could not be detected anymore at further stages. Applying poor pre-harvest agricultural practices such as the use of certain varieties (Jasmine, DT8 varieties), combination of fertilizers (organic-inorganic), fields with crop debris, unhygienic boats, and delayed drying time of 8-12 h or 12-28 h resulted in an increase in fungal contamination on paddy. This study provides a detailed description of fungi contamination in crop seasons, cultivation regions, and agricultural practices, which may help in understanding the fungal dynamic and allow identification of good agricultural practices to mitigate the fungal contamination and potential mycotoxin production.
本研究评估了作物季节、种植区域和传统农业 practices 对越南湄公河三角洲水稻产业链中 和 发生情况的影响。2017年至2019年期间，在采样的同时对收获前和收获后的 practices 进行了调查。结果表明， （36.3%）和 （10%）在整个水稻产业链中普遍存在。这些真菌在芹苴稻田的冬春作物和秋冬作物中频繁出现。特别是， 在田间和运输过程中均有出现（50-100%），而 在所有阶段均有出现（10-33%）。与田间和运输阶段相比，干燥后 的发生率降低了70-27%，这取决于季节，在后续阶段则无法再检测到。采用不良的收获前农业 practices，如使用某些品种（茉莉、DT8品种）、肥料组合（有机-无机）、有作物残茬的田地、不卫生的船只以及延迟干燥时间8-12小时或12-28小时，会导致稻谷上的真菌污染增加。本研究详细描述了作物季节、种植区域和农业 practices 中的真菌污染情况，这可能有助于了解真菌动态，并有助于确定良好的农业 practices，以减轻真菌污染和潜在的霉菌毒素产生。
