| Abstract | ||
| The prevalence and incidence of bakanae disease were determined through an investigation in the rice fields of 21 rice-growing districts of Bangladesh from 2020 to 2022. During investigation, bakanae was observed in the rice fields of 16 districts in where Habiganj, Brahmanbaria, Kishoreganj and Netrokona were found to be more prevalent (70-80%) for bakanae. The highest disease incidence was observed in Habigonj (8%) and Brahmanbaria (5 %) when cultivated with the rice variety BRRI 29 and BRRI 28, respectively. It was also noticed that the prevalence and incidence of disease was high in Kishoreganj, Netrokona, Habiganj, Brahmanbaria district where both BRRI 29 and BRRI 28 variety were cultivated. It is concluded that the haor area viz. Habiganj, Brahmanbaria, Kishoreganj and Netrokona were most prone and the rice variety BRRI 29 and BRRI 28 were susceptible to bakanae in the rice growing areas of Bangladesh. Therefore, variety selection should be considered carefully for sustainable rice yield. | ||
