Abstract
Efficacy of KIH-2023 applied POST at rates of 15 to 40 g ai/ha was evaluated in dry-seeded and water-seeded rice production in 1994 and 1995. Purple ammannia, ducksalad, and Indian jointvetch control with KIH-2023 was similar, and alligatorweed control was greater with KIH-2023 compared with propanil or tank mixtures of propanil plus thiobencarb in water-seeded rice. Barnyardgrass was controlled similarly with KIH-2023 and sequential applications of propanil in dry-seeded rice. Rice yields generally reflected differences in weed control, with yields of rice treated with KIH-2023 similar to sequential propanil applications or propanil plus thiobencarb in dry-, and water-seeded rice, respectively. Minor rice foliar and root injury were noted with KIH-2023. Nomenclature: KIH-2023, sodium 2,6-bis[(4,6-dimethoxypyrimidin-2-yl)oxy]benzoate; propanil, N-(3,4-dichlorophenyl)propanamide; thiobencarb, S-[(4-chlorophenyl)methyl]diethylcarbamothioate; alligatorweed, Alternanthera philoxeroides (Mart.)
