IMPACT OF FUNGICIDAL EFFICACY IN THE MANAGEMENT OF BLAST AND SHEATH BLIGHT DISEASE IN RICE UNDER TEMPERATE CONDITIONS

摘要

Results depicted that blast disease symptoms appearing on leaf and panicles can be effectively managed by spraying tricyclazole 0-75 WP (Beam) 0.06%, hexaconazole 0-5 EC (Contaf), benlate 0-50 WP (Benomyl) and bitertanol 25 WP (Baycor) @ 1% concentration of each fungicide. However, hexaconazole 5 EC (Contaf) was most toxic to the sheath blight disease (49.9%) followed by carbendazim-50 WP (Bavistin). Whereas disease index of neck rot was recorded at par in all the evaluated fungicides but tricyclazole 75 WP proved more toxic than rest of the fungicides.
