Abstract

Bakanae disease has been reported from almost all the rice growing countries in the world. The disease has been emerged as a major problem in some of the Asian countries including Bangladesh. Bakanae is becoming a serious threat to sustainable rice production in Bangladesh particularly in the northeastern part of the country and accounted for causing up to 25% yield losses. The disease has become difficult to manage due to lacking appropriate disease diagnosis. Fusarium fujikuroi mainly caused this disease but other Fusarium species are also reported to be involved for causing this disease. It, therefore, is crucial to understand the association of Fusarium species with Bakanae disease for sustainable rice disease management in Bangladesh. Asian J. Med. Biol. Res.

Highlights

Bangladesh is the 3rd rice producing country in the world after China and India
In 1953, Bakanae was first detected in Bangladesh (Anonymous, 1958) by the Mycology and Plant Pathology Division, Bangladesh Agricultural Research Institute (BARI) but it was first described in Japan in 1828 (Ito, 1931)
In Bangladesh, yield loss due to Bakanae was estimated up to 25% (Hossain et al, 2011) which has directly been affected into total rice production in Bangladesh

Summary

Introduction

Bangladesh is the 3rd rice producing country in the world after China and India. In Bangladesh, total rice growing area is 11.90 million ha which covers about 75% of the total cultivable area and the total production is 36 million metric tonnes (USDA Report, 2020). Rice plant is infected by several diseases by fungus, bacteria, virus, nematode etc. Bakanae has become an important emerging disease across Bangladesh in the northeastern part (Haor areas).
