Among the fungal diseases causing significant yield loss in rice, sheath blight ranked the second most important rice disease worldwide after blast. A study on compatibility was undertaken with effective fungicide Hexaconazole 5% SC with insecticides and micronutrient under field condition with treatments laid out in a randomized block design (RBD) with three replications at the Agricultural Research Station, Gangavati, during Kharif 2012 and Summer 2012-13. The results revealed that Sheath blight incidence was minimum in the treatments with Hexaconazole 5% SC alone and in combination with Buprofezin 20% + Acephate 50% WP during both seasons. The efficacy of Hexaconazole was not affected due to the combination with Buprofezin 20% + Acephate 50% WP. During Kharif, the combined treatment recorded 16.53 per cent disease incidence with a yield of 73.7 q/ha, compared to 17.63 per cent and 63.5 q/ha, respectively, with Hexaconazole alone. Similarly, during summer, the combination treatment resulted in 14.43 per cent disease incidence and the highest yield (77.3 q/ha). The grain yield data indicated that, Hexaconazole 5% SC in combination with Buprofezin 20% + Acephate 50% WP record the higher yield compared to the individual treatments and the untreated control. Hence, Hexaconazole 5% SC is compatible with Buprofezin 20% + Acephate 50% WP with respect to enhanced grain yield in rice.
