Early blight disease of tomato caused by Alternaria solani is one of the most destructive diseases which cause considerable loss in tomato production. In the absence of resistant cultivars, the management of tomato early blight disease has relied principally on the application of chemical fungicides. The present study evaluated the effects of chemical fungicides on tomato early blight disease and investigated the efficacy of the yield of tomato plants. The field experiment used a randomised block design, with seven treatments and three replications in subtropical climatic condition of West Bengal at Regional Research Sub-Station (R & L Zone), Bidhan Chandra Krishi Viswavidyalaya, Sekhampur, Birbhum, West Bengal, India during Rabi, 2016-17 and Rabi, 2017-18. Two times foliar spray at an interval of 15 days with Azoxystrobin 11% + Tebuconazole 18.3% SC @ 1000 ml/ha was best followed by Azoxystrobin 18.2% + Difenoconaole 11.4% SC @ 1000 ml/ha and Trifloxysytrobin 25% + Tebuconazole 50% WG.The findings of the present study demonstrated a promising approach of management of early blight disease of tomato with chemical fungicides
