Antifungal effects of low environmental risk compounds on development of pear postharvest diseases: Orchard and postharvest applications
Lutz, María Cecilia; Colodner, Adrian Dario; Tudela, Marisa Andrea Alumine; Carmona, Marcelo Anibal; Sosa, María Cristina (Elsevier, 2022-03)In the main productive area of Argentina, decays caused by Botrytis cinerea, Alternaria alternata, and Alternaria spp. lead to important postharvest losses in pears during medium- and long-term storage. In view of the ... -
Antifungal susceptibility profile and molecular identification of Cyp51C mutations in clinical and environmental isolates of Aspergillus flavus from Argentina
Hermida‐Alava, Katherine; Brito Devoto, Tomás; Sautua, Francisco José; Gordó, Manuela; Scandiani, María Mercedes; Formento, Angela Norma; Luque, Alicia; Carmona, Marcelo Anibal; Cuestas, María L. (Wiley, 2020-10)Background: The emergence of azole resistance in non‐fumigatus Aspergillus strains is on the raise. Objectives: To study the susceptibility profiles and the molecular mechanisms of azole resistance of environmental and ... -
Characterization of DMI, QoI and SDHI fungicides sensitivity of Ramularia collo‑cygni isolates in Argentina
Erreguerena, Ignacio Antonio; Havis, Neil David; Heick, Thies Marten; Gorniak, Kalina; Quiroz, Facundo Jose; Carmona, Marcelo Anibal (Springer, 2022-06-23)Ramularia leaf spot (RLS) caused by the fungus Ramularia collo-cygni (Rcc) has become a threat to barley production in Argentina. All barley varieties are susceptible to RLS; thus, disease management relies on fungicides ... -
Comparative analysis of Argentinian and European populations of Ramularia collo-cygni on barley
Erreguerena, Ignacio Antonio; Hoebe, Peter N.; Carmona, Marcelo Anibal; Guillin, Eduardo Alejandro; Havis, Neil D. (Wiley, 2024-03-19)Ramularia collo-cygni (Rcc) is a major barley pathogen that causes yield and grain quality losses worldwide. The main sources of Rcc inoculum are the seed and asexual airborne spores. In Argentina, Rcc is considered to be ... -
Current recommendations and novel strategies for sustainable management of soybean sudden death syndrome
Rodriguez, Maria Cecilia; Sautua, Francisco José; Scandiani, María Mercedes; Carmona, Marcelo Anibal; Asurmendi, Sebastian (Wiley, 2021-10)The increase in food production requires reduction of the damage caused by plant pathogens, minimizing the environmental impact of management practices. Soil-borne pathogens are among the most relevant pathogens that affect ... -
Draft genome sequence data of Cercospora kikuchii, a causal agent of Cercospora leaf blight and purple seed stain of soybeans
Sautua, Francisco José; Gonzalez, Sergio Alberto; Doyle, Vinson P.; Berretta, Marcelo Facundo; Gordó, Manuela; Scandiani, María Mercedes; Rivarola, Maximo Lisandro; Fernandez, Paula Del Carmen; Carmona, Marcelo Anibal (Elsevier, 2019-10)Cercospora kikuchii (Tak. Matsumoto & Tomoy.) M.W. Gardner 1927 is an ascomycete fungal pathogen that causes Cercospora leaf blight and purple seed stain on soybean. Here, we report the first draft genome sequence and ... -
Eficiencia de transmisión de Trichoconiella padwickii a coleoptilos de arroz en distintos sustratos
Lovato Echeverría, Alfonso D.; Gutierrez, Susana Alejandra; Carmona, Marcelo Anibal (Ediciones INTA, 2021-12)El hongo Trichoconiella padwickii es uno de los principales patógenos de la semilla de arroz en la provincia de Corrientes, Argentina. Con el objetivo de cuantificar la eficiencia de transmisión (Et) desde la semilla a ... -
Fungicide resistance in Cercospora species causing cercospora leaf blight and purple seed stain of soybean in Argentina
Sautua, Francisco José; Doyle, Vinson P.; Price, Paul P.; Porfiri, Alejandro; Fernandez, Paula Del Carmen; Scandiani, María Mercedes; Carmona, Marcelo Anibal (Wiley, 2020-12)Cercospora species cause cercospora leaf blight (CLB) and purple seed stain (PSS) on soybean. Because there are few resistant soybean varieties available, CLB/PSS management relies heavily upon fungicide applications. ... -
Modelling of the effects of environmental factors on rice grain discoloration incidence in Corrientes province, Argentina
Dirchwolf, Pamela M.; Moschini, Ricardo Carlos; Gutierrez, Susana A.; Carmona, Marcelo Anibal (Wiley, 2023-01)Rice grain discoloration (RGD) is a disease of complex aetiology for which there are no resistant varieties. Due to the need to better define the environmental conditions that favour the disease, the aims of this work were ... -
