Abstract: Chickpea is one of the major pulse crop affected by various diseases, the rust caused by (Uromyces ciceris-arietini) (Grogon) Jacz. & Boyer is considered as one of the most distructive disease of chickpea. Rust pathogen affects in all growth stages results in substantial losses in terms of both quality and quantity parameters of grain and this reinforces the need to exploit several management strategies including chemical control. Therefore, present investigation was carried out to examine the efficacy of total of twelve chemicals fungicides alone and/or in combination against rust disease of chickpea in two independent locations viz., Arabhavi and Dharwad during 2017-18. The field experiment consisting of three replication and thirteen treatments. The results of the experiment revealed that all the twelve fungicides tested were found effective for the management of chickpea rust disease as compare to control (water spray). However spray combination of Tebuconazole 50% + Trifloxystrobin 25% w/w 75 WG @ 1.0 g/l twice at onset of disease significantly reduced rust incidence with record of 14.28 PDI with high total yield of 12.36 qtl/ha followed by Tebuconazole 25 EC @1 ml/l recorded 15.72 PDI with yield of 12.22qtl/ha, Propioconazole 25EC @1.0 ml/lit (Tilt) recorded 16.41 PDI with higher yield of 11.17 qtl/ha) found effective in reducing the disease. While, Difenoconazole 25 EC@1 ml/l showed 17.45 PDI and yield of 10.56qtl/ha, Tebuconazole 50% + Trifloxystrobin 25% w/w 75WG @ 0.5 g/l recorded 18.25 PDI and 10.36qtl/ha of yield and Pyraclostrobin 25 EC @1 ml/l observed with 20.02 rust PDI with yield of 10.32qtl/ha showing equally effective in reducing rust percent disease incidence and increased yield when compared to control that recorded highest rust disease incidence (53.71 PDI) and lower yield (6.16 qtl/ha).
