Controlled-release herbicide formulations have significant role in slow release of herbicides under laboratory and field conditions. In the present study kaolin, clay and saw dust were used to sorb the herbicide butachlor to test the slow release formulations of herbicides and their kinetic retention behavior in water. Release of different formulations of butachlor and oxadiazon were also studied. Desorption of oxadiazon formulations OA1 showed higher release (93.98±0.34%) than OA2 (43.73±0.45%), butachlor formulations BH1 exhibited higher release (99.29±0.33%) than BH2 (59.45±0.30%) on 28th day. It was experimentally confirmed that clay and saw dust as a coating material have high adsorption rate (77.2%), found to increase the holding capacity of butachlor rather than kaolin and the release was very slow which may avoid herbicide loss by environmental degradation. Organoclays and saw dust may find application as better sorbents of herbicides than kaolin and this will be a promising formulation in the environmental and economic point of view. © 2007 Asian Network for Scientific Information.
