| dc.description | This investigative work consisted of compiling all the necessary information in different sources, of information on the cultivation of rice (Oryza sativa L) and corn (Zea mays L.), since it is very essential for the feeding of the national and world population, In addition, these two crops generate a very important economic income for farmers. In addition, it provides a source of work for the people who are in charge of cultivating it. It can be said that certain weeds serve to prevent soil erosion, in addition that some weeds serve as medicinal plants and for food purposes, since they recycle mineral nutrients from the soil, despite this there are several plants that are not arable and are called "undesirable" where the crop is different and for this reason they are considered weeds, because they are products of the alterations of the natural vegetation, since they constitute the most important economic component of the total pest complex, since they incorporate vertebrate insects, nematodes, and plant pathology. To avoid competition with the crop for light, water, nutrients and space, it is recommended to control weeds correctly, apply post-emergence herbicides in the rice crop (Oryza sativa, L) and in corn, in both planting stages, we must also evaluate the incidence that weeds have on crops and thus avoid economic losses to producers. | es_ES |

| dc.description.abstract | Este trabajo investigativo consistió en recopilar toda la información necesaria en diferentes fuentes, de información sobre el cultivo de arroz (Oryza sativa L) y maiz (Zea mays L.), ya que es muy indispensable para la alimentación de la población nacional y mundial, además estos dos cultivos generan un ingreso economico muy importante para los agricultores. Ademas, brinda fuentes de empleos y es el sustento de las personas que se encargan de cultivarlo. Se puede decir, que ciertas malezas sirven para prevenir la erosión del suelo, además que algunas malezas sirven como plantas medicinales y para fines alimenticios, ya que reciclan nutrientes minerales del suelo, a pesar de ello hay varias plantas que sin cultivables que se denominan como “indeseables” en lugares donde el cultivo son diferentes y por ello son consideradas como malezas, porque son un efecto de la variacion de la vegetación natural que establece el factor económico más fundamental y total del complejo de plagas ya que incorpora insectos vertebrados, nematodos, y patógenos de plantas. Para evitar competencias con el cultivo por luz, agua y nutrientes y espacio se recomienda controlar las malezas eficazmente, aplicar herbicidas postemergentes en el cultivo de arroz (Oryza sativa, L) y en el maiz, en ambas etapas de siembra, también debemos de evaluar la incidencia que tienen las malezas en los cultivos y así evitar pérdidas económicas a los productores. | es_ES |
