Studies on the Control of Caesulia axillaris Roxb. in Transplanted Rice (Oryza sativa L.)
Abstract
Metsulfuron-methyl and 2, 4-D were evaluated for the control of broadleaf weeds particularly Caesulia axillaris in transplanted paddy from 1995 to 1998. Post-emergence (25 days after transplanting) spray application of metsulfuron-methyl at 10 and 15 g/ha and 2, 4-D (Na salt) at 0.6 and 0.8 kg/ha provided good control of C. axillaris and significantly increased grain yield over standard practice of two hand pullings. On an average, metsulfuron-methyl 10 g/ha and 2, 4-D 0.6 kg/ha increased grain yield of rice by 23.1 and 62.5% as compared to the hand pullings and control treatments, respectively.
