| dc.description | Sugarcane represents an important sector of the productive agricultural area, in which many people depend on this crop, carrying out various activities that range from planting, agronomic management, harvest, industrialization, transportation and marketing. In the growth and development of the sugarcane crop, there is a stage known as the critical period of competition, where weeds are harmful. This critical period of competition for sugarcane ranges from emergence to 5 months of age, where the crop is affected by competition for water, light, nutrients, and space. These weeds can reduce production under permanent conditions up to 97.5%. The most economically important weeds in sugarcane are: Cyperus rotundus, Digitaria ciliaris, Panicum hurticaule, Cyperus esculentus, Brachiaria fasciculata and R. cochinchinensis. Weed control methods include indirect (preventive) and direct (cultural and curative) methods. There are several methods for weed control in order to reduce their infestation to a certain level, which do not cause damage, the most used are the following: preventive, physical, cultural, chemical, biological and other unconventional methods. The information obtained was made by means of the analysis, synthesis and summary technique, in order for the reader to know about the importance of weed management in the cultivation of sugar cane. For the above detailed it was determined that in the cultivation of sugar cane weeds can be controlled within the first three or four months of their development. This critical stage of competition is fundamental for the future development of sugarcane and must be taken into account in the pre-emergent and post-emergent chemical control programs for weeds. In order to carry out efficient weed control in sugarcane cultivation, it is important to take into account the various factors such as: the predominant weed species, the state of development of the weeds and their relation to the crop, the equipment available for control, the weather conditions and soil moisture content to start the respective control. | es_ES |

| dc.description.abstract | La caña de azúcar representa un sector importante del área agrícola productiva, en la cual muchas personas dependen de este cultivo, realizando diversas actividades que van desde la siembra, manejo agronómico, cosecha, industrialización, transporte y comercialización. En el crecimiento y desarrollo del cultivo de caña de azúcar, se presenta una etapa conocida como periodo crítico de competencia, en donde las malezas son perjudiciales. Este periodo crítico de competencia de la caña de azúcar abarca desde la emergencia hasta los 5 meses de edad, donde el cultivo se ve afectado por la competencia de agua, luz, nutrientes y espacio. Estas malezas pueden reducir la producción en condiciones permanente hasta el 97.5 %. Las malezas de mayor importancia económica en caña de azúcar son: Cyperus rotundus, Digitaria ciliaris, Panicum hurticaule, Cyperus esculentus, Brachiaria fasciculata y R. cochinchinensis. Los métodos de control de malezas comprenden los métodos indirectos (preventivos) y los directos (culturales y curativos). Existen varios métodos para el control de las malezas con la finalidad de reducir su infestación a un determinado nivel, que no causen daños, los más utilizados son los siguientes: preventivos, físicos, culturales, químico, biológico y otros métodos no convencionales. La información obtenida fue efectuada mediante la técnica de análisis, síntesis y resumen, con la finalidad de que el lector conozca sobre la importancia del manejo de malezas en el cultivo de caña de azúcar. Por lo anteriormente detallado se determinó que en el cultivo de caña de azúcar las malezas pueden ser controladas entre los primeros tres o cuatro meses de su desarrollo. Esta etapa crítica de competencia, es fundamental para el futuro desarrollo de la caña de azúcar y debe de tomarse en cuenta en los programas de control químico pre emergente y post emergente a las malezas. Para realizar un control eficiente de malezas en el cultivo de caña de azúcar es importante tener en cuenta los varios factores como: las especies de malezas predominantes, estado de desarrollo de las malezas y su relación el cultivo, el equipo disponible para el control, las condiciones de clima y contenido de humedad en el suelo para iniciar el control respectivo. | es_ES |
