dc.descriptionResidual herbicides being in contact with the soil, remain active for months, due to their movement, these herbicides should be used to handle species that come from seeds, both broadleaf (broadleaf) and grasses. Residual herbicides are designed to control weeds in their early stages of improvement, i.e., while the epidermis of the future plant is at its minimum expression. Most residual herbicides have an effect on photosynthesis or cell division and growth, but a few herbicides appear to affect a couple of factors. Thus, bromoxynyl nitrile inhibits photosynthesis and uncouples oxidative phosphorylation. Herbicides of the same chemical organization usually have the same movement, but this is not always continuously the case. The information obtained was carried out through the technique of analysis, synthesis and summary, with the purpose of informing the reader about the importance of residual herbicides and their mechanisms of action on weeds. From the above, it was determined that there are three elements that influence the efficacy of residual herbicides applied to the soil: soil moisture, soil texture and organic matter content, the characteristics of the active component and the dose of herbicide used. The factors that define the persistence of a herbicide in soil can be grouped into three main factors: (1) factors that define the adsorption of herbicides to soil colloidal micelles, (2) climatic factors, and (3) characteristics or elements based on crop management. All residual herbicide adsorption processes are mediated by soil characteristics, physico-electrical properties of herbicide molecules, and factors affecting water movement within plants. The most commonly used residual herbicide molecules are Simazine 50%, Oxyfluorfen, Diuron 50%, Pendimethalin, Trifluralin, Oryzalin, Flumioexazin Dichlobenil, Indaziflam and Terbuthylazine 50%.es_ES

dc.description.abstractLos herbicidas residuales estando en contacto con el suelo, siguen siendo activos durante meses, debido a su movimiento, estos herbicidas deben utilizarse para manipular las especies que provienen de semillas, tanto de hoja ancha (latifoliadas) como de gramíneas. Los herbicidas residuales están diseñados para controlar las malas hierbas de sus primeros grados de mejora, es decir, mientras la epidermis de la futura planta está en su mínima expresión. La mayoría de los herbicidas residuales tienen un efecto sobre la fotosíntesis o la división celular y crecimiento, pero unos pocos herbicidas parecen afectar a un par de factores. El nitrilo de bromoxinilo reprime la fotosíntesis y no permite la fosforilación oxidativa. Los herbicidas de la misma organización química suelen tener el mismo movimiento, pero esto no es siempre continuamente el caso. La información obtenida fue efectuada mediante la técnica de análisis, síntesis y resumen, con la finalidad de que el lector conozca sobre la importancia de los herbicidas residuales y sus mecanismos de acción en malezas. Por lo anteriormente detallado se determinó, que existen tres elementos que influyen en la eficacia de los herbicidas residuales aplicados al suelo: la humedad del suelo, la textura del suelo y el contenido de materia orgánica, las características del componente activo y la dosis del herbicida utilizado. Existen factores que catalogan la persistencia de un herbicida en el suelo siendo tres factores principales: (1) factores que definen la adsorción de los herbicidas a las micelas coloidales del suelo, (2) factores climáticos y (3) características o elementos basados en el manejo del cultivo. Todos los procesos de absorción de herbicidas residuales están mediados por las características del suelo, las propiedades físico-eléctricas de las moléculas herbicidas y los factores que afecten el movimiento del agua dentro de las plantas. Las moléculas de herbicidas residuales más utilizados son Simazina 50%, Oxifluorfen, Diuron 50%, Pendimetalin, Trifluralina, Oryzalin, Flumioexazin Dichlobenil, Indaziflam y Terbutilazina 50%.es_ES
