Transmisión por semilla y control de la antracnosis del caupí,causada por Colletotrichum dematium, (Pers. ex Fr) Grove.

Seed transmission of Colletotrichuin dematiuin through cowpea seeds, and its control with fungicide seed treatments was studied at the Turipaná National Research Center of ICA (Colombian Institute of Agriculture) located in Cereté (Córdoba). Two out of eight genotypes tested showed significantly h...

Two out of eight genotypes tested showed significantly higher (a = 0.01) seed infection levels; they also exhibited higher seed transmission rates of C. de,natiuin. Treatment of infected seeds of line Licatur-1 with Benomyl (Benlate WP50, 3.0 gr/kg of seed) caused a significant reduction of seed infection levels (a = 0.01), and resulted in comparable decreases in anthracnose incidence, measured 24 days after seedling emergence in sand germinators. The effect of seed lot, soil type and fungicide seed treatment on anthracnose incidence was also evaluated. Results indicated a highly significant effect of seed lots, partially explained by environmental and seed crop management variations. Anthracnose incidence, decreased when the seeds were planted in a clay loam soil as compared to disease incidence in sand. Seed treatment with benomyl (Benlate WP50, 2.5 .3.0 gr/kg) or Mancozeb (Dithane M-45, 5.0 yr/kg) caused a significant reduction in anthracnose incidence. These results suggest that fungicide seed treatment is an effective control practice to prevent spread of C. de,natiu,n through cowpea seeds. En las instalaciones del Centro Nacional de Investigaciones Turipaná, del Instituto Colombiano Agropecurio, ICA (Cereté-Córdoba), se estudió la transmisión de Colletotrichum dematium a través de semillas de caupí, y su control mediante el tratamiento de semillas con fungicidas. De 8 genotipos estudiados, 2 exhibieron niveles significativamente más altos (alfa igual a 0.01) de infección de semilla, y mayores tasas de transmisión de C. dematium a las plantas de caupí. El tratamiento de semilla infectada de la línea Licatur-1 con Benomyl (Benlate PM50, 3.0 gr/kg de semilla) redujo su nivel de infección y la incidencia de antracnosis en plantas de 24 días de edad creciendo en germinadores de arena. El efecto del lote de semilla, el tipo de suelo y el tratamiento de semilla con fungicidas en la incidencia de antracnosis, también fue estudiado. Los resultados indicaron diferencias entre lotes de semilla, debidas posiblemente a variaciones climáticas y de manejo en la producción de los diferentes lotes. La incidencia de antracnosis fue significativamente más baja en suelo arcilloso que en arena. El tratamiento de semilla con Benomyl (Benlate PM50, 2.5-3.0 gr/kg) o Mancozeb (Dithane M-45, 5.0 gr/kg) redujo la incidencia de antracnosis, por lo cual se considera como un método efectivo para prevenir la diseminación de C. dematium a través de semillas de caupí Fríjol-Phaseolus vulgaris 2019-09-06T17:56:35Z 2019-09-06T17:56:35Z 1990 article Artículo científico http://purl.org/coar/resource_type/c_2df8fbb1 info:eu-repo/semantics/article https://purl.org/redcol/resource_type/ART http://purl.org/coar/version/c_970fb48d4fbd8a85 0018-8794 http://hdl.handle.net/20.500.12324/35413 17615 reponame:Biblioteca Digital Agropecuaria de Colombia repourl:https://repository.agrosavia.co instname:Corporación colombiana de investigación agropecuaria AGROSAVIA spa Revista ICA 4 265 274 Attribution-NonCommercial-NoDerivatives 4.0 International http://creativecommons.org/licenses/by-nc-nd/4.0/ Acceso a texto completo info:eu-repo/semantics/openAccess application/pdf application/pdf Córdoba Cereté C.I Turipaná Colombia Instituto Colombiano Agropecuario Bogotá (Colombia) Revista ICA; Vol. 25, Núm. 4 (1990): Revista ICA Octubre-Diciembre);p. 265-274
