Field evaluation of different fungicides against Uromyces ciceris-arietini causing rust in chickpea in northern Karnataka

Abstract

A field experiment was conducted to evaluate different fungicides against chickpea rust caused by Uromyces ciceris-arietini at Main Agricultural Research Station (MARS), Dharwad and ARS, Arabhavi during Rabi 2017 and 2018. The data on percent disease index and seed yield of chickpea for two years and two locations were pooled and revealed that, less percent disease index was observed in spray with Tebuconazole 50%+ Trifloxystrobin 25% w/w 75WG @ 0.5 g/l water and it was found effective in managing the disease with 15.81%. It was followed by Tebuconazole 25 EC @1.0 ml/l (16.60 %) and Propiconazole 25 EC @1 ml/l (18.06 %) and these are on par with each other. Highest percent disease index of 62.12 % was observed in untreated control. Seed yield of 12.38 q/ha was found in spray with Tebuconazole 50 %+ Trifloxystrobin 25% w/w 75WG @ 0.5 g/l water followed by 11.85 q/ha in spray with Tebuconazole 25 EC @1.0 ml/l water and 11.27 q/ha in spray with Propiconazole 25 EC @1 ml/l water. Minimum seed yield of 6.03 q/ha was found in untreated control.
