The purpose ofthis study was to investigate burn down and residual efficacy of flumioxazin tank mixtures. Flumioxazinwas tank mixed at 1.0 and 1.5 oz/a with 2,4-D + glyphosate or at 1.0 oz/a withchlorimuron&thifensulfuron+ glyphosate. Standards in the study were 2,4-D+glyphosate,metribuzin+paraquat, linuron+paraquat, 2,4-D+paraquat and chlorimuron&thifensulfuron+2,4-D+quizalofop-P. Other treatments evaluated were chlorimuron&thifensulfuron+tribenuron+2,4-D+quizalofop-P, tribenuron+2, 4-D+quizalofop-P, chlorimuron&thifensulfuron+sulfentrazone+2,4-D+quizalofop-P, and thifensulfuron+quizalofop-P. Weed species evaluated were white campion(MELAL), corn speedwell (VERAR), and giant foxtail (SETFA). Soybeans were planted on May 30 at adepth of 0.5 inches in 7-inch rows.
