Aerial spread of smut spores during peanut harvest
(Springer, 2024-03-18)Peanut smut (Thecaphora frezzii) is one of the most important peanut diseases in Argentinian peanut production. This monocyclic soil-borne pathogen transforms kernels into spore masses. Spore liberation from broken infected ... -
Decoding peanut smut: A bibliometric analysis of two decades of research progress
(Springer, 2024-01-22)Since its first detection in commercial peanut fields in 1995, both the prevalence and impact on yield of peanut smut disease, caused by the fungus Thecaphora frezzii, have increased significantly. Concurrently, diverse ... -
Draft genome sequence data of Nothopassalora personata, peanut foliar pathogen from Argentina
(Elsevier, 2024-04)Late leaf spot (LLS) caused by the Ascomycete Nothopassalora personata (N.p.) (Syn. Cercosporidium personatum) is the main foliar disease of peanuts in Argentina and in peanut producing areas of the world, causing up to ... -
Efecto de nuevos fungicidas en el control de viruela del maní y el rendimiento del cultivo
(Facultad de Agronomía y Veterinaria, Universidad Nacional de Río Cuarto, 2018-07)Las enfermedades son el principal problema sanitario del maní (Arachis hypogaea L.), siendo viruela (Cercospora arachidicola Hori y Cercosporidium personatum (Berck. & Curt Deighton)) la más importante del mundo, y la que ... -
Efficacy of fungicides against peanut smut in Argentina
(Elsevier, 2020-09-28)Peanut smut, caused by Thecaphora frezii, increased its incidence and prevalence in the main growing region of Argentina in the last decade becoming the main peanut disease. Despite this fact, growers continue producing ... -
Examples of Risk Tools for Pests in Peanut (Arachis hypogaea) Developed for Five Countries Using Microsoft Excel
(Entomological Society of America, 2022-08-03)Suppressing pest populations below economically-damaging levels is an important element of sustainable peanut (Arachis hypogaea L.) production. Peanut farmers and their advisors often approach pest management with similar ... -
Exploring species composition and population dynamics of thrips (Thysanoptera: Thripidae) in peanut crops in Argentina
(Springer, 2021-04-26)Thrips (Thysanoptera: Thripidae) are major pests of peanut (Arachis hypogaea L.). They cause feeding damage and indirect injuries transmitting plant viruses. In Argentina, peanut is commonly affected by thrips. The crop ... -
First draft genome of Thecaphora frezii, causal agent of peanut smut disease
(BMC, 2023-02-16)Objectives: The fungal pathogen Thecaphora frezii Carranza & Lindquist causes peanut smut, a severe disease currently endemic in Argentina. To study the ecology of T. frezii and to understand the mechanisms of smut resistance ... -
Low water availability increases susceptibility to peanut smut (Thecaphora frezzii) in peanut crop
(Wiley, 2023-10-23)Peanut smut (causal agent Thecaphora frezzii) and seasonal drought are the two main factors reducing peanut yields in Argentina. There are no previous studies about the effect of drought on peanut smut occurrence. We ... -
Mitogenome and Nuclear-encoded Fungicide-target Genes of Thecaphora frezii - Causal Agent of Peanut Smut
(Longdom Publishing, 2019-08-28)Background: Thecaphora frezii Carranza and Lindquist causes smut disease in peanut (Arachis hypogaea L.) resulting in up to 35% yield losses. Fungicides have shown ineffective in controlling the disease; whereas research ... -
Molecular detection of Thecaphora frezzi in peanut (Arachis Hypogaea L.) seeds
(2016)Thecaphora frezii is the causal agent of peanut smut, important disease in the Argentine production area. The pathogen can be dispersed by kernels, through surface contamination or small lesions. The aim of this work was ... -
Molecular sequence data of Thecaphora frezii affecting peanut crops in Argentina
(Springer, 2013-12)In Argentina, Thecaphora frezii is the causal agent of peanut smut, causing severe yield losses in peanut growing areas. In this work sequence data of the large ribosomal subunit (28S rDNA) of four T. frezii specimens from ... -
Morphological and molecular characterization of Nothopassalora personata from Argentina
(Springer, 2023-01-10)Late leaf spot (LLS) is the most important foliar disease of peanuts in Argentina and in other peanut production areas, causing defoliation and yield losses. In this study, six isolates obtained from symptomatic leaflets ... -
Orthotospovirus disease epidemic: molecular characterization and incidence in peanut crops
(Springer, 2020-10-13)Argentina is one of the main peanut (Arachis hypogaea L.) exporting countries with the major peanut-growing area located in the province of Córdoba. During the 2015–2016 growing season, severe outbreaks of an orthotospovirus-like ... -
Peanut Smut : from an emerging disease to an actual threat to Argentine Peanut production
(2017-03)The center of origin of peanut is located in South America, specifically in southeastern Bolivia and northwestern Argentina, where its parental species are found in wild habits. Even though Argentina is only the seventh ... -
Relationship between incidence and severity of peanut smut and its regional distribution in the main growing region of Argentina
(Springer, 2021-10-20)Peanut smut, caused by the soil-borne pathogen Thecaphora frezii, has increased in incidence in the main Argentinian peanut-growing regions. Smut-affected pod transform the kernel into a mass of teliospores, which survive ...
