Sesame (Sesamum indicum L.) is an important oilseed crop. Foliar diseases viz., Alternaria leaf spot and powdery mildew cause major threat in sesame cultivation. The effect of various fungicides in managing foliar diseases of sesame was studied under field conditions. Seed treatment with Trichoderma asperellum @ 10 g/kg seed and furrow application of T. asperellum ( kg/ha mixed in 100 kg of FYM) @ 250 kg/ha is common for all the treatments. Spraying with various systemic fungicides was taken first at the time of initiation of the disease and second at 15 days after first spraying. Among the fungicides tested, spraying of myclobutanil @ 1 g/l twice was effective in managing the foliar diseases of sesame and also increasing the seed yield. | 2019 8 6 3086-3090 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 06 2019 Journal homepage http Original Research Article https Fungicides in the Management of Foliar Diseases of Sesame B.

Introduction Among the oilseed field crops sesame Sesamum indicum L. is one of the most important ancient oil-yielding crop in the world for edible oil production. Sesame seed is a rich source of protein 20 edible oil 50 oleic acid 47 and linolenic acid 39 Kumaraswamy et al. 2015 . It is also a rich source of natural antioxidants viz. sesamoline sesamin and sesamol Shyu and Hwang 2002 . Although sesame is widely used for different purposes it has low productivity due to non-availability of high-yielding varieties resistant variety to biotic and abiotic stresses low harvest index seed shattering and indeterminate growth .
