Various Methods for Controlling the <i>Bakanae</i> Disease in Rice

Abstract

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.

Variations in Morpho-Cultural Characteristics and Pathogenicity of Fusarium moniliforme of Bakanae Disease of Rice and Evaluation of In Vitro Growth Suppression Potential of Some Bioagents

“…Gupta et al [8] revealed that some strains of Trichoderma, Pseudomonas, and Bacillus have anti-fungal effects against bakanae disease. A similar finding was investigated by Jing and Suga [17]. Therefore, the introduction of biocontrol agents may be an innovative treatment capable of suppressing bakanae disease to be used instead of chemical treatment.…”

“…Among them, P. fluorescens, B. cereus, and Trichoderma spp. isolates have an excellent potential to be used as biocontrol agents of F. fujikuroi in rice [16,17]. The capacity of these organisms to colonize roots and their beneficial interactions with plants can lead to an efficient defense against the disease, since they can trigger host defense responses against Fusarium spp.…”
