The experiments were conducted to evaluate safening effect of fenclorim (CGA 123'407, 4,6-dichloro-2-phenyl pyrimidine) against injuries of pretilachlor, butachlor, and benthiocarb in direct-seeded rice under flooded conditions. Pretilachlor and butachlor and benthiocarb reduced crop standing and inhibited growth of rice plants. However, premixture application of pretilachlor, butachlor or benthiocarb with fenclorim at 10-30 g ai/10a greatly reduced rice injury caused by the application of each herbicide alone and thus increased crop standing plant height and dry weight of rice plants compared to herbicide treatments alone.

Field study was conducted to evaluate safening effect of fenclorim (4,6-dichloro-2-phenyl pyrimidine) against benthiocarb, butachlor, and pretilachlor injury in rice plants under vinyl-covered subirrigated seedbed. Combinated application of benthiocarb 210, and 315 g ai/10a with fenclorim 10 g ai/10a or higher concentration, butachlor 180, and 270 g ai/10a with fenclorim 20 g ai/10a or higher concentration, and pretilachlor 60, and 90 g ai/10a with fenclorim 30 g ai/10a reduced herbicide injury of rice, and thus increased standing, plant height, tillers, and dry weight of rice plants compared to no combined application of fenclorim.
