description | Crop Protection Online (CPO) is a decision support system, which integrates decision algorithms quantifying the requirement for weed control and a herbicide dose model. CPO was designed to be used by advisors and farmers to optimize the choice of herbicide and dose. The recommendations from CPO for herbicide application in spring barley in Denmark were validated through field experiments targeting three levels of weed control requirement. Satisfactory weed control levels at harvest were achieved by a medium control level requirement generating substantial herbicide reductions (∼ 60% measured as the Treatment Frequency Index (TFI)) compared to a high level of required weed control. The observations indicated that the current level of weed control required is robust for a range of weed scenarios. Weed plant numbers 3 wk after spraying indicated that the growth of the weed species were inhibited by the applied doses, but not necessarily killed, and that an adequate level of control was reached later in the season through crop competition. Nomenclature: Spring barley; Hordeum vulgare L. Crop Protection Online (CPO, Protección de Cultivos en Línea) es un sistema de ayuda para la toma de decisión, el cual integra algoritmos que cuantifican el requerimiento de control de malezas y un modelo de dosis de herbicidas. CPO fue diseñado para ser usado por asesores y productores para optimizar la selección de herbicidas y dosis. Las recomendaciones de CPO para la aplicación de herbicidas en cebada de primavera en Dinamarca fueron validadas mediante experimentos de campo enfocados a tres niveles de requerimientos de control de malezas. Niveles satisfactorios de control de malezas al momento de la cosecha se alcanzaron con un nivel de requerimiento de control medio, lo que generó reducciones sustanciales de herbicidas (∼60% medido como el índice de frecuencia de tratamiento (TFI)) al compararse con el nivel de requerimiento de control de malezas alto. Las observaciones indicaron que el nivel actual de requerimientos de control de malezas es robusto para un rango amplio de escenarios de malezas. Los números de plantas de malezas, 3 semanas después de la aplicación, indicaron que el crecimiento de las especies de malezas fue inhibido por las dosis aplicadas, pero estas no necesariamente murieron, y que un nivel adecuado de control fue alcanzado después en la temporada debido a la competencia del cultivo. |
