| dc.description.abstract | Root-rot complex in clusterbean caused by Rhizoctonia bataticola, Fusarium solani and Sclerotium rolfsii is a major disease of clusterbean [Cyamopsis tetragonoloba (L.) Taub] in Haryana. The inoculum age of 7 days old culture, inoculum density of 50g/kg soil, soil temperature of 30oC, soil moisture of 30 per cent water holding capacity (WHC) and soil pH of 6.0 were found to be optimum for disease development in three varieties, viz. FS-277, Pusa Nav Bahar (PNB) and HG-75. Garlic extract at 20 per cent concentration was found most effective against root-rot complex which showed maximum inhibition of the pathogen, i.e., 90.25 per cent under laboratory conditions. Under screenhouse conditions garlic extract at 20 per cent concentration in HG-75 was found most effective against the pathogens which exhibited minimum seedling mortality (4.75%). Trichoderma harzianum was found an effective antagonist against root-rot complex which showed maximum inhibition of the pathogen, i.e., 73.77 per cent under laboratory conditions. Under screenhouse conditions Trichoderma harzianum in HG-75 was found most effective against the pathogens which exhibited minimum seedling mortality (5.50%). Among organic amendments mustard residue and vermicompost when applied in combination @ 5g/kg soil resulted in maximum disease control, i.e., 11.75 per cent seedling mortality in HG-75. | en_US |
