The seed borne disease such as bakanae is difficult to control. Crop yield loss caused by bakanae depending on the regions and varieties grown, ranging from 3.0% to 95.4%. Bakanae is an important disease of rice worldwide and the pathogen was identified as Fusarium fujikuroi Nirenberg (teleomorph: Gibberella fujikuroi Sawada). Currently, four Fusaria ( F. fujikuroi, F. proliferatum, F. verticillioides and F. andiyazi ) belonging to F. fujikuroi species complex are generally known as the pathogens of bakanae. The infection occurs through both seed and soil-borne transmission. When infection occurs during the heading stage, rice seeds become contaminated. Molecular detection of pathogens of bakanae is important because identification based on morphological and biological characters could lead to incorrect species designation and time-consuming. Seed disinfection has been studied for a long time in Korea for the management of the bakanae disease of rice. As seed disinfectants have been studied to control bakanae, resistance studies to chemicals have been also conducted. Presently biological control and resistant varieties are not widely used. The detection of this pathogen is critical for seed certification and for preventing field infections. In South Korea, bakanae is designated as a regulated pathogen. To provide highly qualified rice seeds to farms, Korea Seed & Variety Service (KSVS) has been producing and distributing certified rice seeds for producing healthy rice in fields. Therefore, the objective of the study is to summarize the recent progress in molecular identification, fungicide resistance, and the management strategy of bakanae.

“…(Lee et al, 2021). Therefore, many different quantitative trait locus (QTL) related to bakanae resistance have recently been identified through QTL mapping, which can be used to perform marker-assisted selection in rice cultivation and resistance mechanisms to bakanae (Lee et al, 2019;Park, 2020). Most QTLs conferring bakanae resistance were identified on chromosome 1 and qBK1 z , qBK1.2, and qBK1.3 are localized in similar regions of different resistant varieties (Lee et al, 2021).…”

“…A QTL from ‘Nampyeong’, a resistant variety, was reported at 87.9–91.7 cM of the same chromosome 1 ( Hur et al, 2015 ; Lee et al, 2018 ). Based on the reported QTLs, ‘Anpyeong’ and ‘MY299BK’ were developed from a cross with ‘Shingwang,’ a variety with qBK1 ( Jo et al, 2020 ).…”

Past and Future Epidemiological Perspectives and Integrated Management of Rice Bakanae in Korea

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.

“…Furthermore, qBK1 WD in the japonica variety Wonseadaesoo [34] and qBK1 Z of the Zenith variety [35] were identified to confer resistance to bakanae disease. Recently, a late maturing cultivar MY299BK which is bakanae resistant was developed by introducing the qBK1 gene from Shingwang [36].…”

Bakanae disease, caused by Fusarium fujikuroi, is a serious problem in rice production. This disease is widespread across the world and leads to substantial yield losses. F. fujikuroi is known to produce various secondary metabolites, including the plant hormone gibberellin, which induces typical bakanae symptoms. In this article, authors overviewed the methods for controlling bakanae disease, including the use of host resistance, chemical compounds, biocontrol agents, natural products, and physical methods. Although various strategies have been applied to control bakanae disease, the disease is not yet completely prevented. Authors discuss the advantages and disadvantages of these various methods. In addition, the mode of action of major fungicides and the resistance mechanisms to these fungicides were outlined. These information contribute to the development of more effective methods for controlling bakanae disease.
