Bakanae (バカナエ, BA-ka-NA-eh) or bakanae disease (Chinese: 馬鹿苗病, Japanese: バカナエビョウ, romanized: Bakanae-byou, [bakanae bʲoɯ]), from the Japanese for “foolish seedling”, is a disease that infects the rice plant. It is caused by the fungus Gibberella fujikuroi, the metabolism of which produces a surplus of gibberellic acid.In the plant, this acts as a growth hormone
filexlib. Bakanae is a seedborne fungal disease. The fungus infects plants through the roots or crowns. It then grows systemically within the plant. Infected plants are abnormally tall with pale, thin leaves, produce fewer tillers, and produce only partially filled or empty grains.
Bakanae disease is widely distributed in all rice growing areas of the world. In Bangladesh, it is one of the major diseases of rice. Four methods were tested for management of this disease, of which, roguing proved ineffective in a field
Bakanae disease is an important fungal disease in the world. No rice (Oryza sativa L.) varieties have been found to be completely resistant to this disease. To facilitate accurate, uniform and simultaneous screening of many rice accessions, we developed an inoculation method for microconidia of Fusarium fujikuroi using a tissue embedding cassette and seedling tray. Standards for evaluating the
Bakanae disease is an emerging problem for the Basmati rice cultivation in India. Forty-seven endophytes isolated earlier along with three Talaromyces flavus isolates evaluated against Fusaium fujikuroi [Nirenberg] bakanae pathogen [isolate F250] through dual culture and enzymatic assays. Out of 50 …
long-term coherence for this emerging disease. History: Bakanae disease was first identified during 1828 in Japan. Shotaro Hori (1898) first time demonstrated the fungus Fusarium heterosporium Nees induced the bakanae symptom in rice plants. It was later put in the genus Gibberella under the name G. fujikuroi (Sawada) (Ito and Kimura, 1931).
In recent years, the incidence of bakanae disease is increasing season to season in the Punjab and Haryana. Development and application of proper management technique will become strong challenge in future in rice based cropping system in the various places of Punjab and Haryana. Introduction year 2016-17. The expected production during the

Rice bakanae disease, caused by Fusarium fujikoroi, is an economically important disease that poses a threat to rice cultivation. It causes serious yield losses quantitatively and qualitatively. The current study aims to suppress rice bakanae disease by using indigenous antagonistic bacteria. The antagonistic bacteria significantly inhibited the growth of F. fujikoroi RB-01% in vitro. Seven Keywords: Bakanae disease, Disease incidence, prevalence, rice INTRODUCTION Rice is one of world’s most favoured staple foods floods, water logging, labour scarcity, intensive pests and grain and about more than 90% of the world’s rice is diseases attacks and lack of policy innovations (Singh produced and consumed in Asian countries (Singh
Bakanae is the major fungal disease of rice posing threat to rice production all over the world. In order to understand the physiological and biochemical basis of resistance, the disease free and Fusarium fujikuroi infected seedlings of two aromatic (PUSA 1121 and PUSA 1509) and two non-aromatic (PR 121 and PR 126) rice cultivars were evaluated. The seeds of rice cultivars were inoculated with

The incidence of bakanae disease was observed in range of 3.4-7.8% in PB-1121 in all surveyed districts. Maximum disease incidence (7.8%) was observed in Baghpat district followed by Hapur (6.7%). In all five districts, over all maximum average disease incidence (5.32%) was observed in PB-1121. Keywords Rice; Bakanae disease; Fusarium moniliformae;
