field experiment was conducted to study the effect of different herbicides alone or in combination, viz. BCSAA 10717-2% + glyphosate (42% SC), BCSAA10717-500 (SC), It is glyphosate (42% SC), glyphosate (41% SC) and paraquat(24 SL) for management of annual and perennial broad-leaved weeds in grapes after October pruning of the year 2010-2011. Herbicide treatments in grape vineyard significantly reduced the total number of weed. Among the tested herbicides, the most effective weed control was recorded with BCSAA 10717 (2%) + glyphosate 42% SC (85.0 + 1700 g/ha) which showed lowest weed density of 22 (4.80) plants/m2 and lowest dry weight (0.212 g) of weed after 30 days. While paraquat (24 SL) found effective in increasing the yield with decreasing competition between grape vine and weed, The highest yield (32.12 t/ha) was found in area where paraquat 24 SL was used for weed control. No phytotoxic signs or symptoms, viz. leaf tip/surface injury, wilting, vein clearing, necrosis, epinasty and /or hyponasty were observed by weed management treatments.
