Field experiment was conducted at Main Agricultural Research Station, UAS, Dharwad , Karnataka for two years, during Kharif, 2012 and Kharif, 2013 to evaluate the new fungicides against leaf spot and rust of groundnut. Experiment was laid out in Randomized Block Design (RBD) with eight treatments and three replications. The variety used was JL 24. Plot size was 3m x 3m. Fluxapyroxad 167 g/l + Pyraclostrobin 333 g/L sc was evaluated at three concentrations viz., 0.04%, 0.05% and 0.06%. Other fungicides evaluated were Fluxapyroxad 300 g/l SC @0.05%, Pyraclostrobin 20% [email protected]%, hexaconazole 5% [email protected]% and carbendazim 50% WP @0.1%. Results revealed that combiproduct, Fluxapyroxad + Pyraclostrobin reduced the leaf spot and rust of groundnut and increased the yield significantly at all the concentrations tested (29.72, 28.89 and 29.54 q/ha, was at par with hexaconazole @ 0.1% (31.20%) and significantly superior to the untreated control(16.20q/ha.).
