Bacterial leaf blight of rice in mid and farwestern Nepal: Preliminary study of disease prevalance in farmers field / Ram Bahadur Khadka    

Public ISBD in Proceedings of the 27th National Summer Crops Workshop, held at Rampur, Chitawan, 18-20 April 2013, Vol. I / Giri, Y.P.     Title : Bacterial leaf blight of rice in mid and farwestern Nepal: Preliminary study of disease prevalance in farmers field Material Type: printed text Authors: Ram Bahadur Khadka ; Sharad Adhikari, Author ; Gopi Shrestha, Author Pagination: 298-302 p. Languages : English (eng) Keywords: Leaf  Blight  ;  Disease  Prevalance Abstract: Bacterial leaf blight is one of the major constraints for rice production in mid and far-western Nepal. Tn case of high intensity, it may cause significant loss in the yield of rice. There is little knowledge about the diversity, pathogenicity and epidemiology of bacterial leaf blight ofrice i.n the regions. A sampling and disease survey were undertaken to identify the incidence of bacterial leaf blight in farmer's field in Banke, Bardiya, Dang and Kail ali districts in main rice growing season of2012. According to survey result, Bindeshowari, Local manshuli, Indrasan , Kalanamak and Sarju # 52 varieties of rice had remarkably higher disease incidence (42.5, 34.66, 85, 65. 73.75%, respectively) at Narayanpur, Dang; Mainpokhar and Beluwa of Bardiya; Khurd Khajura, Banke and Chuba, Manuwa, Partapur and Janakinagar of Kailali district, respectively. Low disease incidence (3.66 and 11 .83%, respectively) were observed in Sabitri and Radha4 varieties of rice at Mainapokhar, Motipur, Kalika and Beluwa of Baridya district; Urhari and Narayanpur of Dang; Makawanpur, Radha 4 and Sabitri varieties at Rajapur, Bardiya, Sukha Dhan 1 and Sukha Dhan 2 at Khurd Kahjura Banke. The survey reveal ed that there is very low awareness among farmers about impact of bacterial leaf blight disease in rice production. Among the surveyed areas only farmers of Narayanpur, Dang; Beluwa, Bardiya; and Rainiyapur, Banke district were found to be more serious to disease management whereas at other places the farmers did not show any interest to disease management. The results obtained in this initial study shows potential research scope and future research thrust on bacterial leaf blight management in mid and far western Nepal.
