Field experiment conducted during winter seasons of 1998–99 and 1999–2000 to evaluate the efficacy of chlorsulfuron, metsulfuron and 2,4–0 ester against Rumex sp. (Jangli palak) revealed that chlorsulfuron 25 and 30 g and metsulfuron 4 and 6 g ha−1 with 0.1% surfactant provided 97 to 98% control of this weed when applied 30 DAS in wheat. Similarly, 2,4–0 ester and sodium at 425 and 1000 g ha−1, respectively, too provided 95 to 98% control of this weed. Maximum crop yields of 5856 and 4754 kg ha−1 were obtained in season long weed free during both the seasons, respectively. Chlorsulfuron 25 and 30 g, metsulfuron+S at 4 g+0.1% or 6 g+0.1%, 2, 4–0 ester at 425 g and 2,4–0 sodium salt at 1000 g ha−1 applied 30 DAS gave more or less similar yields to that of weed free yields in both the seasons. Chlorsulfuron at 25 and 30 g, metsulfuron 4 and 6 g with 0.1% surfactant can be recommended to control jangli palak alongwith 2,4–0 in wheat.
