This study was carried out to evaluate tolerance in selected local rice cultivars (Oryza sativa L.) to different concentrations of the herbicide metolachlor. The study was conducted in a netted greenhouse at University Putra Malaysia Bintulu Campus, Sarawak using 44 x 32 x 12 cm high trays filled with a sandy clay loam soil. A total of 13 rice cultivars were screened for tolerance to metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl) acetamide]. The cultivars were MR 220, MR 219, MR 185, MR 84, Serendah Kuning, Padi Satu, Acheh 62, Buntar B, Sampangan B, Lasak, Serasan Puteh, Rotan and Bario. The treatment consisted of three levels of metalachlor at 0.5, 0.25, and 0.125 kg ai/ha and an untreated control in 8 replications. The cultivar tolerance responses to metolachlor were evaluated with respect to seedling emergence, height and weight. The result of the study showed that, Serendah Kuning, Acheh 62, and Buntar B appear to have some degree of tolerance to metolachor with tolerance indices for seedling growth ranging between 1.056 and 1.602 at the highest herbicide rate tested.
