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 : Validation of farmers indigenous knowledge to manage mungbean yellow mosaic virus in blackgram Material Type: printed text Authors: Dhana Bahadur Gharti ; Subash Subedi, Author ; Tek Nath Ghimire, Author Pagination: 319-322 p. Languages : English (eng) Keywords: Mungbean  Yellow  Mosaic  Gemini  virus,  farmers'  indigenous  knowledge,  Bemisia  tabaci, Ageratum  spp Abstract: This study was undertaken at Grain Legume Research Program, Rampur during 2067/068(2010/1 I) and 2068/069 (2011 / 12) with a view to validate farmers' indigenous knowledge on Mungbean Yellow Mosaic Virus disease management in blackgram. During 2067/068 six treatments viz. cow's milk spray, seed priming, cow's urine spray, mohi spray, turmeric powder suspension spray and control were tested. Tn the fiscal year 2068/069 the treatments were modified as cow's milk spray, seed priming with sodium molybdate , cow's urine spray, spray of extract of mixture of botanicals and control. Weed host of the virusAgeratum spp and whitefly (Bemisia tabaci Glenn) vector populations were found abundant in both the years. Blackgram genotype used in the first year was BLG 0003-2-l (moderately tolerant to MYMV) and Chanpbas Local (highly susceptible to MYMV) in the second year. None of the treatments were statistically significant to manage MYMV in both the years. However, cow's milk spray reduced disease severity, increased hundred seed weight and improved grain yield during 2067/068 and spray of leaf extract of mixture of botanicals reduced disease severity and increased grain yield to some extent in the second year. Disease severity was less in the first year due to the use of moderately tolerant genotype and very high during the second year because of the use of highly susce ptible cultivar. Since the virus is vector borne and there is abundance of alternate and collateral hosts in terai and inner terai use of resistant/ tolerant varieties, vector control and removal of alternate and collateral hosts are some of the possible ways to manage MYMV in blackgram, soybean and mungbean Link for e-copy: http://elibrary.narc.gov.np/?r=918 in Proceedings of the 27th National Summer Crops Workshop, held at Rampur, Chitawan, 18-20 April 2013, Vol. I / Giri, Y.P.     Validation of farmers indigenous knowledge to manage mungbean yellow mosaic virus in blackgram [printed text] / Dhana Bahadur Gharti ; Subash Subedi, Author ; Tek Nath Ghimire, Author . - [s.d.] . - 319-322 p.
