Abstract

Crop safety is one of the many considerations when deciding which POST herbicide to use. This research examined relative corn injury as a result of POST herbicides and the effect of including the safener isoxadifen, the choice of a sensitive or tolerant hybrid, or both. The herbicides included commercial combinations of dicamba, diflufenzopyr, nicosulfuron, rimsulfuron, and thifensulfuron, all at twice the labeled rate. Isoxadifen reduced twisting from dicamba plus diflufenzopyr but not with dicamba plus rimsulfuron. Isoxadifen had negligible effect on chlorosis. In general, rimsulfuron plus thifensulfuron caused the most corn stunting, whereas including isoxadifen or using a tolerant hybrid often reduced corn injury. In two of the four years, treatments with rimsulfuron plus thifensulfuron resulted in yield reductions. Although using products with isoxadifen or selecting tolerant hybrids may influence injury, herbicide selection will have the greatest effect on corn injury.

La seguridad en el cultivo es una de las muchas consideraciones cuando se decide cuáles herbicidas POST y a qué dosis se usarán estos. Esta investigación examinó el daño relativo del maíz como resultado de herbicidas POST y el efecto de incluir isoxadifen como antídoto, el efecto de la selección de híbridos sensibles o tolerantes, y la combinación de estos dos factores. Los herbicidas incluyeron combinaciones comerciales de dicamba, diflufenzopyr, nicosulfuron, rimsulfuron, y thifensulfuron, todos al doble de las dosis de etiqueta. Isoxadifen redujo el enrollamiento causado por dicamba más diflufenzopyr, pero no con dicamba más rimsulfuron. Isoxadifen tuvo un efecto mínimo sobre la clorosis. En general, rimsulfuron más thifensulfuron causaron el mayor retraso en el crecimiento del maíz, mientras que el incluir isoxadifen o usar un híbrido tolerante frecuentemente redujo el daño al maíz. En dos de los cuatro años, los tratamientos con rimsulfuron más thifensulfuron resultaron en reducciones en el rendimiento. Aunque el usar productos con isoxadifen o seleccionar híbridos tolerantes podría influenciar el nivel daño, la selección de los herbicidas tendrá el mayor efecto en el daño que sufrirá el maíz.
