Abstract
Neck blast is considered as the most destructive phase of the blast disease in rice under south-eastern Rajasthan. Eight new generation fungicides viz., Tebuconazole, Difenconazole Propiconazole , Hexaconazole Azoxystrobin , Azoxystrobin +Tebuconazole ,Azoxystrobin Mancozeb Trifloxystrobin +Tebuconazole were evaluated under field conditions during Kharif 2021. Result revealed that the combination of Trifloxystrobin (25%) + Tebuconazole (50 WG @ 0.4g/lit) gave minimum disease intensity (3.2%) and maximum disease control (80.8%) with higher yield (4482.3 kg/ha) which was at par with Propiconazole with a grain yield of4400.0 kg/ha.
