| dc.description | This document provides information on the integrated management of late foliar disease, caused by Cercosporidium personatum, in peanut crops (Arachis hypogaea L.). The general objective was to determine the integrated management of leaf spot (Cercosporidium personatun) in the cultivation of peanuts (Arachis hypogaea L.). To prepare the document, a compilation of information from magazines, virtual libraries, books and recent scientific articles was carried out. The results show that it is essential to carry out sowing during warm and dry periods to prevent the development of the disease. The symptoms manifest as a small, circular, brown spot, commonly surrounded by a yellowish halo. Late Smallpox has generated serious obstacles in its management, therefore, producers have decided to harvest the crop early. The conclusions determined that the symptoms of late spot disease (C. Personatum) are characterized by the formation of small circular black lesions, which generally lack a yellowish halo. Subsequently, these spots tend to increase in size to form an irregular lesion that covers the entire leaf. The damage causes decreases in yield caused by the defoliation of the plants, between 5 and 35% depending on the planting period. Among the integrated leaf spot management methods, it is determined that there is no etiological control; However, cultural control is applied such as manual weed control and the use of resistant materials; chemical control such as the application of fungicides containing mancozeb and chlorothalonil at a dose of 1.5 kg/ha and chlorothalonil at 0.8 kg/ha and biological control with the use of Bacillus Trichoderma harzianum, together with Azadirachta indica extracts. | es_ES |

| dc.description.abstract | El presente documento proporciona información sobre el manejo integrado de la enfermedad foliar tardía, causada por Cercosporidium personatum, en el cultivo de maní (Arachis hypogaea L.). El objetivo general fue determinar el manejo integrado de la mancha foliar (Cercosporidium personatun) en el cultivo de maní (Arachis hypogaea L.). Para la elaboración del documento, se llevó a cabo una recopilación de información proveniente de revistas, bibliotecas virtuales, libros y artículos científicos recientes. Los resultados demuestran que es fundamental llevar a cabo la siembra durante períodos cálidos y secos para prevenir el desarrollo de la enfermedad. La sintomatología se manifiesta como una pequeña mancha de forma circular y color marrón, comúnmente rodeada por un halo de tonalidad amarillenta. La Viruela Tardía ha generado serios obstáculos en su manejo, por lo tanto, los productores han decidido realizar la recolección anticipada del cultivo. Las conclusiones determinaron que los síntomas de la enfermedad mancha tardía (C. Personatum), se caracteriza por la formación de pequeñas lesiones circulares de color negro, que generalmente carecen de un halo amarillento. Posteriormente, estas manchas tienden a aumentar de tamaño para conformar una lesión irregular que abarca la totalidad de la hoja. Los daños provocan disminuciones en el rendimiento causado por la defoliación de las plantas, entre un 5 y 35 % dependiendo del periodo de siembra. Entre los métodos de manejo integrado de la mancha foliar se determina que no existe control etiológico; sin embargo se aplica el control cultural como control de malezas manual y el uso de materiales resistentes; el control químico como la aplicación de fungicidas que contienen mancozeb y clorotalonil en dosis de 1,5 kg/ha y clorotalonil en 0,8 kg/ha y el control biológico con el uso de Bacillus Trichoderma harzianum, junto con los extractos de Azadirachta indica. | es_ES |
