| Summary, etc |
La presente investigación se realizó con el propósito de determinar métodos eficaces para el control del Coyolillo (Cyperus rotundus L.), una maleza altamente agresiva que afecta el desarrollo de los cultivos en zonas tropicales. Se evaluaron distintos productos herbicidas con el fin de identificar el más efectivo y la dosis económicamente viable para los agricultores. Los resultados demostraron que el Coyolillo representa una de las malezas más difíciles de erradicar por su resistencia a los herbicidas y su capacidad de reproducción vegetativa, lo que reduce significativamente la productividad y el valor comercial de los terrenos agrícolas. |
