| dc.description | The genus Leptochloa consists of about forty species and its center of distribution is located within the subtropical and warm regions of the world. However, its variety has developed dramatically outside these regions, thanks to human activity (agriculture and exchange of seeds and plant webs). The genus Leptochloa has a magnificent dispersal potential due to the convenience of spikelet disarticulation, which occurs with the slightest friction or movement of the plant, and the enormous amount of fruit that can be generated. The information obtained was carried out by means of the technique of analysis, synthesis and summary, with the purpose of informing the reader about the morphological characterization of the weeds of the genus Leptochloa. From the above detailed it was determined that the important weed species of the genus Echinochloa are: Leptochloa filiformis. Leptochloa chinensis, Leptochloa chloridiformis, Leptochloa uninervia, Leptochloa panicea and Leptochloa virgata, which can reduce crop yields due to direct competition for nutrients, water, light and space. For the management of weed species of the genus Leptochloa spp. there are several alternatives such as cultural and chemical practices that favor the management and control of Leptochloa spp. The herbicides profoxydim (AURA-Basf) and cyhalofop butyl (CLlNCHER-Dow Agrosciences) effectively control Leptochloa spp. when the weed has 1-2 leaves. | es_ES |

| dc.description.abstract | El género Leptochloa consta de unas cuarenta especies y su centro de distribución se sitúa dentro de las regiones subtropicales y cálidas del mundo. Sin embargo, su variedad se ha desarrollado drásticamente fuera de estas regiones, gracias a la actividad humana (agricultura e intercambio de semillas y telas vegetales). El género Leptochloa tiene un magnífico potencial de dispersión debido a la conveniencia de la desarticulación de las espiguillas, que se produce con el más mínimo roce o movimiento de la planta, y a la enorme cantidad de frutos que pueden generar. La información obtenida fue efectuada mediante la técnica de análisis, síntesis y resumen, con la finalidad de que el lector conozca sobre la caracterización morfológica de las malezas del género Leptochloa. Por lo anteriormente detallado se determinó que las especies de malezas importantes del género Echinochloa son: Leptochloa filiformis. Leptochloa chinensis, Leptochloa chloridiformis, Leptochloa uninervia, Leptochloa panicea y Leptochloa virgata, las misma que pueden reducir los rendimientos de los cultivos, por la competencia directa por nutrientes, agua, luz y espacio. Para el manejo de las especies de malezas del género Leptochloa spp. existen diversas alternativas como prácticas culturales y químicas que favorecen el manejo y control de las especies de Leptochloa spp. Los herbicidas profoxydim (AURA-Basf) y cihalofop-butilo (CLlNCHER-Dow Agrosciences) controla eficazmente las especies del género Leptochloa, aplicándose cuando la maleza tiene 1-2 hojas. | es_ES |
