Considering the importance of leaf blight of wheat caused by Alternaria triticina, the feld study was conducted using different fungicides. The different fungicides like, Mancozeb 75% WP, Propineb 70% WP, Hexaconazole 5% SC, Propiconazole 25 % EC, Azoxystrobin 11% + Tebuconazole 18.30% SC and Hexaconazole 4% + Zineb 68% WP tested as foliar spray under feld conditions the lower disease intensity (15.79 %) was recorded in foliar application of Propiconazole 25 % EC (500 ppm) followed by Hexaconazole 4 % + Zineb 68 % WP (18.44 %) at 1000 ppm. The maximum grain yield (3831 kg/ha) was also recorded in foliar spray of Propiconazole 25 % EC which was at par with Hexaconazole 4 % + Zineb 68 % WP and Hexaconazole 5 % SC.

Wheat crop having more nutritional value, the nutritional composition indicated that 100 g of bread wheat provides 326-335 calories and it consists carbohydrates 71 g, protein 14 g, fat 2.5 g, minerals 2 g and considerable proportions of vitamins (thiamine and vitamin-B) and minerals (zinc and iron) (Wolde et al., 2016). It is known for its remarkable adaptation to a wide range of environments and its role in world economy. Three species of wheat viz., Triticum aestivum (bread wheat), Triticum durum (macaroni wheat) and Triticum dicoccum (emmer wheat) are presently grown as commercial crop in India. Globally wheat has 224.98 million hectares area, 735.50 million metric tons production and 3.27 metric tons per hectare productivity and in India wheat has 30.78 million hectares area, 98.51 million metric tons production and 3.20 metric tons per hectare productivity during 2016-17 (Anon., 2018). In Gujarat wheat has 0.99 million hectares area, 2.73 million metric tons production and 2.75 metric tons per hectare productivity during 2016-17 (Anon., 2017). Leaf blight caused by Alternaria triticina, Helminthosporium sp., Curvularia sp. etc. but Alternaria triticina is widely prevalent in wheat growing areas especially in Eastern and South- Central India ( Joshi et al., 1978). It causes serious damage in crops as well as in grain yield (Chenulu et al., 1967). During 1963-64 wheat season, the outbreak of the disease was so severe at the botanical sub-station, Pusa, Bihar. That not a single genetic stock under cultivation had escaped the disease (Prasada and Prabhu, 1964). The leaf blight of wheat caused by Alternaria triticina is one of the most important diseases of wheat causing considerable losses in Rajasthan on the high yielding Mexican varieties. Prabhu and Prasada (1966) reported that as the disease progresses, the irregularly scattered necrotic spots coalesce and cover large areas resulting in the death of entire leaf. In case of severe infection, the symptoms may appear on the leaf sheath, seed and wild host in the soil.
