Sheath blight disease has become a major threat in rice cultivation throughout India. Management of sheath blight is difficult due to soil borne nature of the pathogen and non availability of resistant varieties to the disease. Use of fungicides is the only effective option in the management of the disease. Therefore, three different field evaluations were undertaken in two seasons to find out effective fungicide formulation in the management of sheath blight. All the fungicides tested were found effective against sheath blight. Application of Hexaconazole 75% WG @ 50 g a.i./ha was found highly effective in controlling sheath blight (9.44%), higher growth as indicated by plant height (95 cm), Leaf area index (3.3), Percent chaffiness (12.5) and increasing the grain yield (5122 kg/ha) when compared to the untreated check (66.66%, 80.1 cm, 2.10,35 and 4179 kg/ha). In the second field experiment application of Tetraconazole 11.6% w/w ME @ 1.0 litre/ha was found highly effective in controlling sheath blight (12.77%) and increasing growth represented by growth parameter like plant height (92.5 cm), leaf area index (3.41), Percent chaffiness (12.2) and increasing the grain yield (4138 kg/ha) when compared to the untreated check (62.77%, 75.5 cm, 2.40,37.5 and 3145 kg/ha). Similarly, Thifluzamide 24% SC @ 110 g ai/ha was found highly effective in controlling sheath blight (8.31%) enhanced plant growth as represented by plant height (94.5 cm), leaf area index (3.29), percent chaffiness (14.3) and increasing the grain yield (5212 kg/ha) when compared to the untreated check (42.06%, 80.0 cm, 2.35, 38.5 and 4341 kg/ha). Combination fungicide Tricyclazole 45% + Hexaconazole 10% WG was found effective against major diseases of rice as it provided better control against blast and sheath blight diseases.

Tea is attacked by a number of pests and diseases which is the major limiting factor in crop productivity. A majority of tea diseases are of fungal origin and more than 800 species of fungi are reported to affect different parts of the tea plant. Tea being a foliage crop, leaf diseases such blister blight and grey blight are of most concern as they lead to direct loss both in yield and quality. To manage both these diseases a new combination fungicide, AVTAR, containing Zineb 68% + Hexaconazole 4% WP was tested under field conditions at Ooty and Gudalur divisions of Nilgiris district for two seasons(North West Monsoon and South East Monsoon, 2008-2009). The pooled mean of two season experimental results in two locations revealed that foliar spraying of Zineb 68% + Hexaconazole 4% WP @ 250 g/acre at 15 days interval was effective in minimizing the severity of both blister blight and grey blight. The green leaf yield of tea also increased significantly due to this treatment.

Tea being a foliage crop is prone to a number of leaf diseases. Blister blight and grey blight diseases are of most concern as it leads to direct loss both in yield and quality. To manage both these diseases a new combination fungicide containing Carbendazim 12% + Mancozeb 63% WP was tested under field conditions at Ooty and Gudalur divisions of Nilgiris district for two seasons (North West Monsoon and South East Monsoon). The pooled mean of two season experimental results in two locations revealed that foliar spraying of Carbendazim 12% + Mancozeb 63% WP twice at the rate of 1250 to 1500 g/ha at 15 days interval was highly effective against grey and blister blight in tea and was equally effective in increasing the yield. This ready-mix fungicide even at higher than the proposed doses was not found to be phytotoxic to tea. The green leaf yield of tea also increased significantly due to this treatment.

Three new Qol fungicides (Kresoxim methyl, Metaminastrobin and Trifloxystrobin) and combinations with other groups were evaluated for two seasons against two important diseases of rice (blast and sheath blight). All the Qol group fungicdides were very effective in controlling leaf blast,- sheath blight and neck blast diseases and also improved the growth of the plant in terms of height, test weight in connection with yield. The combination fungicides Kresoxim methyl 40% + Hexaconazole 8% SC @ 200 + 40 g a.i/ha and Metominostrobin 20 SC + Hexaconazole 5 SC (Contai) @ 150 + 37.5 g ai/ha showed good synergistic effect, which provided good control of blast and sheath blight diseases.
