Morphological Studies and Its Biological Management Practices of Fusarium Wilt (Fusarium oxysporum F.sp. Lini) of Linseed

Abstract

The experiment was carried out in a warehouse at the Department of Plant Pathology at C.S. Azad University of Agriculture and Technology in Kanpur with the aim of Isolation, purification, identification & pathogenicity of linseed wilt pathogen, integrated disease management practice against Fusarium wilt, soil colonizing ability of Trichoderma viride in sick field plots, Effect of different pH levels and different temperature levels on the growth and sporulation of the pathogen (in- vitro). The experiment used an RBD design On eleven cultivars out of eleven cultivars (Jeevan, Shweta, Parvati, Surbhi, Shekhar, NDL-2004-05, Kiran, RLC-92, Indira Alsi, Dipika, and Chambal) tested, the minimum percentage of wilting was recorded in cultivar RLC-92 (6.64 percent) followed by Jeevan (8.85 percent) and Indira Alsi (9.70 percent), respectively but all were at par statistically, with 13 treatments, by reducing plant wilting, all treatments were found to be noticeably better than the control (untreated) at reducing disease severity, among all treatments minimum percent wilting with maximum disease control was recorded with treatment T4 [seed treatment (5g/kg seed) + soil treatment with Trichoderma harzianum (10g/kg soil) followed by T2 (5 g/kg seed) + soil treatments with Trichoderma viride (10 g/soil)] (19.46 percent) and T12 (seed and soil treatment with carbendazin (0.2 percent) (23.50 percent), respectively under pot culture condition.
