Various Methods for Controlling the Bakanae 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.
