Abstract

In the past, rice bakanae was considered an endemic disease that did not cause significant losses in Korea; however, the disease has recently become a serious threat due to climate change, changes in farming practices, and the emergence of fungicide-resistant strains. Since the bakanae outbreak in 2006, its incidence has gradually decreased due to the application of effective control measures such as hot water immersion methods and seed disinfectants. However, in 2013, a marked increase in bakanae incidence was observed, causing problems for rice farmers. Therefore, in this review, we present the potential risks from climate change based on an epidemiological understanding of the pathogen, host plant, and environment, which are the key elements influencing the incidence of bakanae. In addition, disease management options to reduce the disease pressure of bakanae below the economic threshold level are investigated, with a specific focus on resistant varieties, as well as chemical, biological, cultural, and physical control methods. Lastly, as more effective countermeasures to bakanae, we propose an integrated disease management option that combines different control methods, including advanced imaging technologies such as remote sensing. In this review, we revisit and examine bakanae, a traditional seed-borne fungal disease that has not gained considerable attention in the agricultural history of Korea. Based on the understanding of the present significance and anticipated risks of the disease, the findings of this study are expected to provide useful information for the establishment of an effective response strategy to bakanae in the era of climate change.

韩国水稻白斑病的流行病学研究与综合治理。
过去,水稻白斑病被认为是一种地方病,在韩国不会造成重大损失;然而,由于气候变化、耕作方式的改变以及抗杀菌剂菌株的出现,这种疾病最近已成为一种严重威胁。自2006年巴卡纳暴发以来,由于采用了热水浸泡法和种子消毒剂等有效控制措施,其发病率已逐渐下降。然而,在2013年,观察到bakanae发病率显著增加,给水稻农民带来了问题。因此,本文在对影响bakanae发病的病原、寄主植物和环境的流行病学认识的基础上,提出了气候变化的潜在风险。此外,还研究了将bakanae的疾病压力降低到经济阈值以下的疾病管理方案,特别侧重于抗性品种,以及化学、生物、文化和物理控制方法。最后,作为更有效的对策,我们提出了一种综合疾病管理方案,结合不同的控制方法,包括先进的成像技术,如遥感。在这篇综述中,我们重新审视和研究bakanae,一种传统的种子传播的真菌疾病,在韩国的农业历史上没有得到相当大的关注。基于对该疾病的当前意义和预期风险的理解,本研究的结果有望为气候变化时代建立有效的应对策略提供有用的信息。
