Field experiments were conducted during kharif 1999 and summer 2000 to study the efficacy of herbicides in controlling weeds in drum seeded rice. The experiments consisted 12 treatments. The herbicides used were sofit, butachlor safener, butachlor, pendimethalin and butanil. The sprouted seeds of rice variety IR-64 was sown. The recommended dose of fertilizers were applied and cono-weeder was passed at 20 and 40 DAS for all the treatments Application of Butachlor safener at 1.25 kg / ha found to be effective in controlling weeds and resulted in higher grain yield of 4762 and 4S62 kg / ha in kharif 1999 and summer 2000, respectively. This treatment also recorded higher net returns of Rs. 16,113 and Rs 16.563/ha in kharif 1999 and summer 2000, respectively, which was closely followed by sofit at 0 6 kg / ha applied 3 DAS Weedy check recorded lower grain yield due to heavy infestation of weeds.
