Late blight disease of tomato caused by Phytophthora infestans is one of the most destructive diseases which cause considerable loss in tomato production. In the absence of resistant cultivars, the management of tomato late blight disease has relied principally on the application of chemical fungicides. The present study evaluated the effects of chemical fungicides on tomato late blight disease and investigated the efficacy of the yield of tomato plants. The field experiment used a randomised block design, with five treatments and four 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, 2020-21 and Rabi, 2021-22. Three times foliar spray at an interval of 10 days with Cymoxanil 8% + Mancozeb 64% WP @ 3.0 g/litre of water was best followed by Famoxadone 16.6% + Cymoxanil 22.1% SC @ 2.0 ml/litre of water and Iprovalicarb 5.5% + Propineb 61.25% WP @ 2.0 g/litre of water. The findings of the present study demonstrated a promising approach of management of late blight disease of tomato with chemical fungicides
