Solanum tuberosum isolate sensitivity to Phytophthora infestans when using three systemic fungicides
Phytophthora infestans is the causative agent of one of the most limiting diseases in potato crops (Solanum tuberosum) in the Department of Nariño, causing farmers to intensively use different fungicides, which reach 30% of production costs and are a serious environmental and public health problem....

| description |
Phytophthora infestans is the causative agent of one of the most limiting diseases in potato crops (Solanum tuberosum) in the Department of Nariño, causing farmers to intensively use different fungicides, which reach 30% of production costs and are a serious environmental and public health problem. The purpose of this research was to support integrated disease management programs based on the generation of a baseline sensitivity of 20 P. infestans isolates from the Department of Nariño to three commercial fungicides composed of Metalaxyl 8% + Mancozeb 64% , Cimoxanil 6% + Propineb 70% and Fluopicolide 6% + Propineb 66.7%. This study was carried out using the in vitro methodology and five doses on an exponential scale. The results showed a heterogeneous behavior where some isolates showed resistance to the fungicide composed of Metalaxil + Mancozeb, reaching average EC50 values of 6.67 μg mL-1; while for the fungicides composed of Cimoxanil + Propineb and Fluopicolide + Propineb, there were intermediate and sensitive sensitivity levels with average EC50 values of 1.57 μg mL-1 and 2.61 μg mL-1. On the other hand, the sporulation rate was reduced in its entirety with the three fungicides for the evaluated doses of 100; 1,000; 10,000 μg mL-1. |

El propósito de esta investigación es apoyar los programas de manejo integrado de enfermedades a partir de la generación de una línea base de sensibilidad de 20 aislamientos de P. infestans del departamento de Nariño frente a tres fungicidas sistémicos comerciales compuestos por Metalaxil 8% + Mancozeb 64%, Cimoxanil 6% + Propineb 70% y Fluopicolide 6% + Propineb 66,7%. Este estudio se llevó a cabo siguiendo la metodología in vitro utilizando cinco dosis basadas en una escala exponencial. Los resultados mostraron un comportamiento heterogéneo donde algunos aislamientos presentaron resistencia al fungicida compuesto por Metalaxil + Mancozeb, alcanzando valores promedio de EC50 de 6,67 µg mL-1, mientras que para los fungicidas compuestos por Cimoxanil + Propineb y Fluopicolide + Propineb se presentaron niveles de sensibilidad intermedia y sensibles con valores de EC50 promedio de 1,57 µg mL-1 y 2,61 µg mL-1. Por otra parte, la tasa de esporulación se redujo en su totalidad para los tres fungicidas cuando se evaluaron las dosis de 100, 1.000, 10.000 µg mL-1.application/pdfspaspaSociedad Colombiana de Ciencias Hortícolas-SCCH and Universidad Pedagógica y Tecnológica de Colombia-UPTChttps://revistas.uptc.edu.co/index.php/ciencias_horticolas/article/view/7859/8549Copyright (c) 2018 Revista Colombiana de Ciencias Hortícolashttps://creativecommons.org/licenses/by-nc/4.0/http://purl.org/coar/access_right/c_abf645http://purl.org/coar/access_right/c_abf2Revista Colombiana de Ciencias Hortícolas; Vol. 12 No. 3 (2018); 592-601Revista Colombiana de Ciencias Hortícolas; Vol. 12 Núm. 3 (2018); 592-601Revista Colombiana de Ciencias Hortícolas; Vol. 12 No 3 (2018); 592-601Revista Colombiana de Ciencias Hortícolas; V. 12 N. 3 (2018); 592-601Revista Colombiana de Ciencias Hortícolas; v. 12 n. 3 (2018); 592-6012422-37192011-2173Resistance to fungicidesPeronosporalCymoxanilFluopicolideMetalaxilPotatoCrop protectionFungicidesResistencia a los fungicidasPeronosporalesCimoxanilFluopicolideMetalaxilPapaProtección de cultivosFungicidasSolanum tuberosum isolate sensitivity to Phytophthora infestans when using three systemic fungicidesSensibilidad de aislamientos de Phytophthora infestans procedentes de Solanum tuberosum a tres fungicidas sistémicosTextTextoTexteTestoTextinfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_7144http://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a728http://purl.org/coar/version/c_970fb48d4fbd8a85Colombia; NariñoColombia; NariñoColombia; NariñoColombia; NariñoColombia; NariñoChañag-Miramag, Harold Andrés Álvarez, Sandra LorenaLagos, Luz EstelaBurbano-David, Diana Marcela001/16828oai:repositorio.uptc.edu.co:001/168282025-07-18 11:49:44.086https://creativecommons.org/licenses/by-nc/4.0/metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |
