Leaf rust of grapes (Vitis vinifera L.) caused by Phakopsora euvitis, is an important disease in the grapes which reduces production. In the absence of resistant cultivars, management of leaf rust disease has relied principally on application of synthetic fungicides. The present study evaluated the control of fungicides against leaf rust disease of grapes. The field experiment was laid in a randomized block design with five treatments each replicated four times in subtropical climatic condition of West Bengal at Regional Research Sub-Station (Red & Laterite Zone), Bidhan Chandra Krishi Viswavidyalaya, Sekhampur, Birbhum, West Bengal, India during 2018-19 and 2019-20. The highest disease control was in Picoxystrobin 22.52% SC @ 400 ml/ha (68.05 %) followed by Azoxytrobin 23 % SC @ 500 ml/ha (57.15%), Kresoxim-methyl 44.3% SC @ 700 ml/ha (46.92%) and Hexaconazole 5% EC @ 1000 ml/ha (38.49 %) on leaves at 15 days after 2nd spray. Highest marketable grapes yield increase was obtained from Picoxystrobin 22.52% SC @ 400 ml/ha (72.91%) followed by Azoxytrobin 23 % SC @ 500 ml/ha (63.55%).
