Abstract

In this study the efficacy of four fungicides, three botanicals and one bio-control agent under field conditions revealed that all the treatments gave reduction of Karnal bunt over check at significant level (P=0.05). Maximum disease control was achieved with Tilt 25EC (48.72%) followed by Bavistin 50WP (47.08 %), Vitavax 75WP (45.30%) and Raxil 2DS (37.61%). Among botanicals L. camara was adjudged best as it gave 41.88 per cent disease control. However, seed treatment of T. viride (Ecoderma) resulted in 28.21 percent disease control. In all treatments over all disease control level was ranged between 28.21 to 48.72 per cent. For effective disease management, source of primary inoculum must be destroy. Primary inoculum of Karnal bunt is present in seed. There-fore, eco-friendly seed treatment of wheat is necessary process for diseases management.
