The potential of alachlor, SAN 582H (Proposed name, dimethenamid), chlorimuron plus metribuzin, clomazone, imazaquin, imazethapyr, metolachlor, sulfentrazone, and trifluralin plus flumetsulam to injure rice the year following application to soybean was evaluated on silty clay and silt loam soils in Louisiana. These herbicides did not cause rice injury or yield reduction. Rice tolerance of the amine salt of 2,4-D or thifensulfuron plus tribenuron applied 0, 7, 14, and 28 d prior to planting was also evaluated on these soils. The amine salt of 2,4-D at 1.1 kg ai/ha injured rice 43 and 52% on silty clay and silt loam soils, respectively, in 1994 when applied the day of planting. In 1995, injury was 78 and 88% on these respective soils at this timing. When applied 7 d or more before planting, 2,4-D amine injured rice in one of four trials. Thifensulfuron plus tribenuron (17 + 9 g ai/ha) injured rice in one of four trials when applied the day of planting, but did not injure rice when applied 7 d before planting. No visual rice injury was observed when 2,4-D amine or thifensulfuron plus tribenuron was applied 14 or 28 d before planting. Rice grain yield was not affected by thifensulfuron plus tribenuron regardless of the interval between application and rice planting. In contrast, rice grain yield was reduced in all trials when 2,4-D amine was applied on the day of planting, and in one of four trials when applied 7 or 14 d before planting.
