Turcicum leaf blight (TLB) and Polysora rust diseases are taking heavy shiver in all maize growing regions of Karnataka. Several new fungicides are used to control the diseases, among them strobilurin group fungicides in combination with triazolefungicides are found effective in management of diseases. A mixture of Trifloxystrobin 50 WG + Tebuconazole 250 EC and mixture of Azoxystrobin 25 SC + Difenoconazole 25 EC were used in this study to manage the TLB and Polysora rust. The two combination fungicides were evaluated in different days against TLB and Polysora rust on two susceptible varieties namely 219J and CM 202. Results revealed that mixture of Trifloxystrobin 50 WG + Tebuconazole 250 EC @ 0.7 g/lit and mixture of Azoxystrobin 25 SC + Difenoconazole 25 EC @ 2.5 ml/litwere found effective in the management of TLB (15.0 % and 11.0 % respectively) and mixture of Trifloxystrobin 50 WG + Tebuconazole 250 EC @ 0.7 g/lit were found effective in controlling Polysora rust (13.2 %). Allied to yield, more significant increase in yield was recorded in treatment Trifloxystrobin 50 WG + Tebuconazole 250 EC @ 0.7 g/lit (5131.1kgs/ha). While, mixtures of Azoxystrobin 25 SC + Difenoconazole 25 EC @ 2.5 ml/lit recorded yield of 5913.0 kgs/ha, this was significantly superior with respect to disease control and yield aspects.
