Rice is an important cereal cop belonging to family Poaceae and its production is affected by many biotic factors viz., diseases caused by bacteria, nematodes and fungal infestation are the most significant constraints causing low yield of this crop in India. The major diseases that affect the economics of rice are bakanae (Fusarium fujikuroi), blast (Pyriculariaoryzae), stackburn (Alternaria spp.) and brown leaf spot (Bipolarisoryzae) of rice. The worldwide annual losses due to rice diseases are estimated to be about 10-15 per cent on an average basis. In Punjab, Bakanae (Foot rot) has become an economically important disease of aromatic rice cultivars. The word Bakanae is of Japanese origin which means naughty bad seedling referred to as foolish seedling. Very high yield losses due to epidemic breakout of bakanae disease were observed in the rice growing areas in Asia where it holds its high economic value (Adam et al., 2018). Bakanae was first noted by Ito and Kimura in 1828 in Japan. During recent years, the prevalence of this disease has been reported from all parts of Asia. The incidence of bakanae disease in India has particularly been reported in aromatic and improved rice cultivars (Bashyal et al., 2014) thereby, having profound effect on quality of seed.

Abstract


Rice is an important cereal cop belonging to family Poaceae and its production is affected by many biotic factors viz., diseases caused by bacteria, nematodes and fungal infestation are the most significant constraints causing low yield of this crop in India. The major diseases that affect the economics of rice are bakanae (Fusarium fujikuroi), blast (Pyriculariaoryzae), stackburn (Alternaria spp.) and brown leaf spot (Bipolarisoryzae) of rice. The worldwide annual losses due to rice diseases are estimated to be about 10-15 per cent on an average basis. In Punjab, Bakanae (Foot rot) has become an economically important disease of aromatic rice cultivars. The word Bakanae is of Japanese origin which means naughty bad seedling referred to as foolish seedling. Very high yield losses due to epidemic breakout of bakanae disease were observed in the rice growing areas in Asia where it holds its high economic value (Adam et al., 2018). Bakanae was first noted by Ito and Kimura in 1828 in Japan. During recent years, the prevalence of this disease has been reported from all parts of Asia. The incidence of bakanae disease in India has particularly been reported in aromatic and improved rice cultivars (Bashyal et al., 2014) thereby, having profound effect on quality of seed.
