To identify effective herbicides against Caesulia axillaris Roxb. in transplanted rice, field studies were carried out at Punjab Agricultural University, Ludhiana during 1992 and 1993. Post-emergence application of naproanilide (1.5 and 2.0 kg/ha), bentazone (1.5 and 2.0 kg/ha) and metsulfuron (0.010 and 0.012 kg/ha) at 10 and 20 days after transplanting (DAT) gave effective weed kill and provided better herbicide efficiency index and grain yield. Anilofos (0.4 kg) and butachlor (1.5 kg/ha) proved ineffective against Caesulia. Higher dose of naproanilide (2.0 kg), metsulfuron (0.012 kg) and bentazone (2.0 kg/ha) gave slight suppression to the crop during initial stages but the crop recovered in due course of time.
