| dc.description | Main associated nematodes in coffee cultivation (Coffea spp). This research was carried out by means of the analysis, synthesis and summary technique, in order to present the results of the main associated nematodes in coffee cultivation (Coffea spp). Nematodes are important in coffee cultivation, the same as during the entire crop cycle and have the ability to adapt in various regions. Among the most important nematode species to see the root system of coffee crops are those of the genus Meloidogyne spp., Pratylenchus spp., Rotylenchulus spp., Helicotylenchus spp. Phytoparasitic nematodes in coffee cultivation can cause various symptoms such as yellowing, leaf fall, slow growth, wilting, low production and depletion, the same that occur by sectors within the plantation. Phytoparasitic nematodes that affect coffee production can be efficiently controlled by chemical control applying Nemacur® 400 CE (Fenamiphos) in doses of 6 L / ha. The use of microorganisms such as Trichoderma spp. and P. lilacinum, should be treated in the phytoparasitic nematode management programs in coffee cultivation. The rhizogenic bacteria Bacillus spp. and Pseudomonas spp. they manage to significantly reduce the populations of phytoparasitic nematodes in coffee cultivation. The application of Beauveria bassiana and Metarhizium anisopliae carried out promising potential for the control of Meloidogyne spp. in coffee seedlings. In the planting and formation of coffee plants in nurseries, the soil solarization process is an effective cultural method to reduce the populations of Meloidogyne spp., Pratylenchus spp. and Helicotylenchus. The application of organic amendments such as chicken manure and coffee pulp to control Meloidogyne spp., Pratylenchus spp. and Helicotylenchus spp in coffee cultivation, increases tolerance to these nematodes, due to increased root mass, and greater availability of nutrients in the soil. Keywords: Coffee, nematodes, symptoms, damage, control. | es_ES |

| dc.description.abstract | Principales nematodos asociados en el cultivo de café (Coffea spp). Esta investigación fue realizada mediante la técnica de análisis, síntesis y resumen, con la finalidad de dar a conocer cuáles son los principales nematodos asociados en el cultivo de café (Coffea spp). Los nematodos son importantes en el cultivo de café, los mismos que afectan durante todo el ciclo del cultivo y poseen la capacidad de adaptarse en diversas regiones. Entre las especies de nematodos más importantes que afectan el sistema radicular del cultivo de café se encuentran las del género Meloidogyne spp., Pratylenchus spp., Rotylenchulus spp., Helicotylenchus spp. Los nematodos fitoparasitos en el cultivo de café pueden causar varios síntomas como amarillamiento, caída de las hojas, crecimiento lento, marchitamiento, baja producción y agotamiento, los mismos que se presentan por sectores dentro de la plantación. Los nematodos fitoparasitos que afectan la producción de café pueden ser controlados de forma eficiente mediante el control químico aplicando Nemacur® 400 CE (Fenamifos) en dosis de 6 L/ha. El uso de microorganismos como Trichoderma spp. y P. lilacinum, deben ser considerados en los programas de manejo de nematodos fitoparásitos en el cultivo de café. Las bacterias rizogénicas Bacillus spp. y Pseudomonas spp. logran reducir significativamente las poblaciones de nematodos fitoparásitos en el cultivo de café. La aplicación de Beauveria bassiana y Metarhizium anisopliae mostraron potencial promisorio para el control de Meloidogyne spp. en almácigos de café. En la siembra y formación de plantas de café en viveros, el proceso de solarización del suelo, es un método cultural eficaz para disminuir las poblaciones de Meloidogyne spp., Pratylenchus spp. y Helicotylenchus. La aplicación de enmiendas orgánicas como la gallinaza y pulpa de café para el control de Meloidogyne spp., Pratylenchus spp. y Helicotylenchus spp en el cultivo de café, incrementa la tolerancia a estos nematodos, debido al aumento de la masa radicular, y mayor disponibilidad de nutrientes en el suelo. | es_ES |
