A roving survey to record sesame Alternaria blight disease intensity was conducted during two Kharif seasons (2014-15 and 2015-16), covering 234 and 240sesame crop fields of nine agro climatic zones, of the Maharashtra state in India, respectively. The results of the survey indicated that overall disease intensity was comparatively higher in the sesame crop grown during Kharif, 2015-16season compared to that of Kharif, 2014-15grown crop. During Kharif, 2014-15 maximum average blight disease intensity of 39.58 per cent was recorded in Central Maharashtra Plateau Zone, followed by the zones viz., Western Maharashtra Plain Zone (37.28 %), Central Vidarbha Zone (35.19 %) and Western Maharashtra Scarcity Zone (32.67 %). In rest of the zones surveyed, the disease intensity was ranged from 21.83 (Western Ghat Zone) to 27.94 (Sub Mountane Zone) per cent. This variability may be due to rainfall pattern, relative humidity, temperature, wind velocity etc. prevailed and a wide range of sesame cultivars grown by the farmers. The pooled mean (Kharif, 2014-15 and 2015-16 ) results revealed maximum mean blight disease intensity in Central Maharashtra Plateau Zone (37.99 %), followed by the zones viz., Western Maharashtra Plain Zone (36.21 %), Central Vidarbha Zone (34.27 %) and Western Maharashtra Scarcity Zone (31.06 %); whereas, it was minimum in the zones of Western Ghat Zone (20.24 %) and North Konkan Coastal Zone (21.82 %). Of various sesame cultivars / varieties grown in the nine agro climatic zones, maximum mean blight disease intensity was recorded on AKT-64 (43.76 %), followed by Local cultivar (40.08 %); whereas, rest of the cultivars exhibited minimum mean blight disease intensity in the range of 19.63 to 32.33 per cent.
