A Survey of Mycoviral Infection in Fusarium spp. Isolated from Maize and Sorghum in Argentina Identifies the First Mycovirus from Fusarium verticillioides
(MDPI, 2020-10)Mycoviruses appear to be widespread in Fusarium species worldwide. The aim of this work was to identify mycoviral infections in Fusarium spp., isolated from maize and sorghum grown in Argentina, and to estimate their ... -
An analysis of the genomic variability of the phytopathogenic mollicute Spiroplasma kunkelii
(American Phytopathological Society, 2013-02)Corn stunt disease has become a factor limiting maize production in some areas of the Americas in recent years. Although resistant maize genotypes have been developed in the past, this resistance has been unstable over ... -
Bottom-up effect of nitrogen fertilization on the density of the corn leafhopper and its impact on both disease incidence and natural parasitism
(Springer, 2022-04-15)The corn leafhopper Dalbulus maidis is a specialist herbivore that attacks maize in the tropical and subtropical regions of the Americas. It is the vector of three relevant plant pathogens that are responsible for severe ... -
Characterization of Argentinian Endemic Aspergillus flavus Isolates and Their Potential Use as Biocontrol Agents for Mycotoxins in Maize
(American Phytopathological Society, 2018-05-07)Maize (Zea mays L.) is a highly valuable crop in Argentina, frequently contaminated with the mycotoxins produced by Aspergillus flavus. Biocontrol products formulated with atoxigenic (nontoxic) strains of this fungal species ... -
Characterization of Components of Resistance to Corn Stunt Disease
(2020-05-28)Considering the occasional but increasing presence of corn stunt disease in the subtropical region of Argentina, the objective of this research was to devise an effective strategy to screen disease-resistant genotypes in ... -
Complete genome sequence of maize yellow striate virus, a new cytorhabdovirus infecting maize and wheat crops in Argentina
(Springer, 2018-01)A rhabdovirus infecting maize and wheat crops in Argentina was molecularly characterized. Through next-generation sequencing (NGS) of symptomatic leaf samples, the complete genome was obtained of two isolates of maize ... -
Differential response of maize hybrids to field infection with Aspergillus flavus and aflatoxin accumulation in the Chaco Semi-arid region of Argentina
(Elsevier, 2022-03-08)Maize is affected by Aspergillus flavus and by the contamination of its kernels with aflatoxins, of which AFB1 is the most important. The Chaco Semi-arid is a region of Argentina in which the climate conditions increase ... -
Estado actual de la sanidad del cultivo de maíz en Argentina
(Asociación Argentina de Productores en Siembra Directa, 2015-02-06)En el país, un factor relevante para la difusión de las enfermedades en el maíz lo constituye el desarrollo y adopción de nuevos escenarios tecnológicos productivos con la incorporación masiva de sistemas de labranza que ... -
First report of johnsongrass mosaic virus in Argentina
(2019-11-21)Potyviruses are responsible for important economic losses in maize crop. This work reports the detection of johnsongrass mosaic virus, a potyvirus affecting maize in Argentina. Electron microscopy studies, mechanical ... -
First report of Maize striatemosaic virus, a mastrevirus infecting Zea mays in Argentina
(Wiley, 2023-06-23)During 2021, sweet corn plants cultivated for human consumption in a 400-ha area in Santa Fe province, Argentina, showed severe virus-like symptoms, including marked dwarfism, plant deformation, nerval or internerval vein ... -
Fungal screening and aflatoxin production by Aspergillus section Flavi isolated from pre-harvest maize ears grown in two Argentine regions
(Elsevier, 2017-02)Aflatoxin contamination in maize kernels grown in central Argentina has increased since 2008. Pre-harvest maize ear samples were collected during two growing seasons to determine prevalent fungal genera as well as aflatoxin ... -
Genome characterization of three potyviruses affecting maize in Argentina
(Wiley, 2023-03-29)Argentina is globally recognized as both producer and exporter of maize, the most important cereal crop in the country. Several potyviruses affect the production of various crops, including maize. In this work, the complete ... -
