Abstract

Field experiments were conducted in 2006, 2007, and 2008 at the Louisiana State University Agricultural Center's Northeast Research Station near St. Joseph, LA, to evaluate imazosulfuron programs involving rate, application timings, and tank mixes for PRE and POST broadleaf weed control in drill-seeded rice. Imazosulfuron showed residual activity against both Texasweed and hemp sesbania. PRE-applied imazosulfuron at 168 g ai ha−1 and higher rates provided 83 to 93% Texasweed control at 4 WAP. At 12 WAP, Texasweed control with 168 g ha−1 and higher rates was 92%. Hemp sesbania control with 168 g ha−1 and higher rates was 86 to 89% at 4 WAP and 65 to 86% at 12 WAP. Imazosulfuron at 224 g ha−1 applied EPOST provided 84 to 93% Texasweed control and 82 to 87% hemp sesbania control, and it was as effective as its tank mixture with bispyribac-sodium. When applied LPOST, four- to five-leaf Texasweed, imazosulfuron alone at 224 g ha−1 was not effective against Texasweed and hemp sesbania, but did improve weed control when mixed with bispyribac-sodium at 17.6 g ai ha−1.

En 2006, 2007 y 2008 se realizaron experimentos de campo en la estación de investigación noreste, del Centro Agrícola de la Universidad Estatal de Louisiana, cerca de St. Joseph, LA, para evaluar programas de imazosulfuron considerando dosis, tiempos de aplicación y mezclas en tanque, para el control PRE y POST de maleza de hoja ancha en arroz sembrado con maquinaria. El imazosulfuron mostró actividad residual contra Caperonia palustris y Sesbania herbacia. El imazosulfuron aplicado PRE a 168 g ia ha−1 y a dosis mayores, proporcionaron de 83 a 93% de control en C. palustris a 4 WAP. A 12 WAP, el control de C. palustris con 168 g ha−1 y a dosis mayores fue de 92%. El control de S. herbacia con 168 g ha−1 y a dosis mayores fue de 86 a 89% a 4 WAP y de 65 a 86% a 12 WAP. El imazosulfuron a 224 g ha−1 aplicado POST temprano, proporcionó de 84 a 93% de control en C. palustris y de 82 a 87% de control en S. herbacia y fue tan efectivo como cuando se mezcló con bispiribac sodio. Imazosulfuron solo asperjado POST tardío en dosis de 224 g ha−1 a C. palustris en su etapa de cuatro a cinco hojas, no fue efectivo contra esta especie ni contra S. herbacia, pero sí mejoró el control de maleza cuando se mezcló con bispiribac sodio a 17.6 g ia ha−1.
