Evaluation of new chemical molecules against sheath blight of rice
Author(s): V Prasad, Saurabh Dixit, SP Giri and DP Singh
Abstract: Sheath blight of rice is one of the major fungal disease causing 25-30% losses in irrigated rice ecosystem. There are no any resistant varieties is available therefore disease management is only by chemical molicules. In view of that eight treatment combinations viz. ICF-110 (Tricyclazole 45%+hexaconazole 10%WG) @1.0g/l, Merger (Tricyclazole 18%+ Mancozeb 62%WP)@ 2.5g/l, Tricyclazole 75%WP @0.6g/l,Hexaconazole 5%EC @ 2.0ml/l, Mancozeb 75%WP @ 2.0g/l, Companian (Mancozeb 63WP+ Carbendazim 12WP) @1.5g/l, Carbendazim 50WP @1.0g/ml and check were evaluated against sheath blight of rice on the susceptible variety Pusa basmati-1 under field condition. Among the new fungicides ICF-110 was found best in checking the disease severity (19.5% & 18.5%) and increased grain yield (61.3% & 57.6% over check) of rice.
