In order to select herbicides which may be feasible to water-seeded rice culture, pot trial was initiated to determine phytotoxicity of rice plants to pyrazolate, bensulfuron methyl, chlormehtoxynil, and benthiocarb under water-seeded condition. Pyraolate at 300 and 600g ai/10a did not show crop injury and growth inhibition of rice plants. Bensulfuron methyl at 5.1g ai/10a and benthiocarb at 210g ai/10a were relatively safe to water-seeded rice plants when treated at 5 days after seeding. Chlormethoxynil at 210g ai/10a showed crop injury and growth inhibition of rice plants and thus may not be feasible to water-seeded rice culture
