Abstract:
A combi-product of Azoxystrobin 16.7% + Tricyclazole 33.3% SC was tested against sheath blight, blast and brown spot diseases of rice under field conditions during Rabi 2019-20 and Kharif 2020-21 at College of Agriculture, Hanumanamatti, Ranebennur (Tq), Haveri (Dist.) Karnataka (State). Three sprays of the chemical Azoxystrobin 16.7% + Tricyclazole 33.3% SC was given at 450 ml/ha, 500 ml/ha and 750 ml/ha respectively. The pooled data indicated that, the least incidence of sheath blight, blast and brown spot diseases (7.20 PDI, 10.38 PDI and 10.38 PDI respectively) was recorded in Azoxystrobin 16.7% + Tricyclazole 33.3% SC at 750 ml/ha followed by Azoxystrobin 16.7% + Tricyclazole 33.3% SC at 500 ml/ha (7.33 PDI, 11.18 PDI and 11.18 PDI of sheath blight, blast and brown spot respectively). Whereas, the untreated control recorded the 20.03 PDI, 21.68 PDI and 21.68 PDI of sheath blight, blast and brown spot respectively. The highest grain yield (5.170 t/ha) and highest net return (Rs.35,240 / ha) was recorded in the treatment with Azoxystrobin 16.7% + Tricyclazole 33.3% SC at 750 ml/ha followed by Azoxystrobin 16.7% + Tricyclazole 33.3% SC at 500 ml/ha (4.900 t/ha and Rs.32,200/ha).
