| dc.description.abstract | El presente documento detalló sobre el manejo de poblaciones de malezas resistentes a herbicidas. Por el tema planteado se determinó que en las provincias de Guayas y Los Ríos se ha notado la resistencia a los herbicidas inhibidores de la enzima ACC-asa a la maleza Leptochloa sp. lo que ha ocasionado que le aplique dosis elevada para que le cause daño, siendo una limitante para los productores de arroz; los herbicidas que causan mayor resistencia frente a un complejo de malezas son los que pertenecen al grupo delos inhibidores ALS (acetolactato sintasa) o a ACC-asa (acetil-coenzima A carboxilasa); cuando existe más diversidad de malezas en los cultivos, existe mayor riesgo de generar resistencia por la probabilidad de generar ineficiencias de control, lo que se atribuye a las técnicas de baja eficacia, uso incorrecto de dosis y equipos y escaso o nulo control en espacios no cultivados como bordes y caminos del cultivo es uno de los factores que también pueden aumentar las formas de resistencia al control de malezas; es necesario cambiar de herbicida utilizar otro que actúe sobre un sitio de acción diferente, a fin de retardar la evolución de resistencia de las malezas a ciertos herbicidas y las buenas prácticas agrícolas son fundamentales en el manejo integrado de malezas, especialmente cuando se sospeche de la existencia de poblaciones resistentes a herbicidas. | es_ES |
