A field experiment to know the efficacy of some new fungicides against neck blast was conducted at Rice and Wheat Research Centre, Malan (HP) during Kharif 2014. New combination product of tricyclazole 18% + mancozeb 62% (MERGER) was found quite effective resulting in 72.6 per cent reduction in disease incidence over control, while application of tricycalzole 75 WP alone reduced neck blast incidence by 69.2 per cent. Another combi-fungicide, ICF-110 (tricyclazole 45% + hexaconazole 10% WG) also resulted in significant reduction (67.8%) in neck blast incidence over control. Also, the new molecules i.e. MERGER and ICF-110 significantly enhanced the grain yield as compared to rest of the fungicides with 192.5 and 176.1 per cent increase in grain yield over control.
