The present experiment was carried out in the experimental farm of Regional Research and Technology Transfer Station (OUAT), Chiplima, Sambalpur, Odisha, during kharif 2013 and Rabi 2013-14 to determine the compatibility of selected insecticides and fungicides against major insect pests like stem borer, brown plant hopper and diseases like blast and sheath blight of rice. The treatments include: T1- Flubendiamide (4%) + Buprofezin (20%) 24 SC @ 875 ml/ha; T2- Triazophos 40 EC @ 750 ml/ha; T3- Hexaconazole 5 SC @ 1000 ml/ha; T4- Tricyclazole 75 WP @ 300 g/ha; T5- T1+T3; T6- T1+T4; T7- T2+T3; T8-T2+T4; T9-untreated control. Among the different combinations tested, Flubendiamide (4%) + Buprofezin (20%) 24 SC in combination with Hexaconazole 5 SC recorded less dead heart (2.22%) and white ear head (2.94%), blast incidence (2.76%), sheath blight incidence (3.55%) and produced highest yield (4.3 t/ha) followed by Flubendiamide (4%) + Buprofezin (20%) SC (2.63%, 3.75%, 3.43%, 4.90% and 4 t/ha) and Flubendiamide (4%) + Buprofezin (20%) 24 SC in combination with Tricyclazole 75 WP (4%, 1.23%, 1.61%, 4.05% and 3.8 t/ha) compared to untreated control where the incidence of DH (11.70%), WEH (12 %), blast incidence (4.60%), sheath blight incidence was 5.7% and produced yield (2.4 t/ha). There was no reduction in the efficacy of these insecticides and fungicides when used as tank mix. No phytotoxicity symptoms were noticed in treated field. So, all the insecticides and fungicides combinations are compatible with each other and can be safely used as tank mix for the control of rice insect pests and diseases, thus, saving labour costs.
