Caracterización morfológica y molecular de cepas nativas de aspergilllus flavus aisladas de espigas de maíz provenientes de diferentes ambientes agrícolas
(Asociación Argentina de Microbiología, 2021-09-15)Una alternativa para reducir los niveles de contaminación con aflatoxinas es el control biológico con cepas de Aspergillus flavus nativas adaptadas al lugar donde se quiere aplicar, que no produzcan aflatoxinas, y que ... -
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 ... -
Drought induces distinct growth response, protection, and recovery mechanisms in the maize leaf growth zone
(2015-10)Drought is the most important crop yield-limiting factor, and detailed knowledge of its impact on plant growth regulation is crucial. The maize (Zea mays) leaf growth zone offers unique possibilities for studying the ... -
Factores extrínsecos e intrínsecos asociados a poblaciones fúngicas micotoxigénicas de granos de maíz (Zea mays L.) almacenados en silos bolsa en Argentina = Extrinsic and intrinsic factors associated with mycotoxigenic fungi populations of maize grains (Zea mays L.) stored in silobags in Argentina
(Asociación Argentina de Microbiología, 2015-10)Con el objeto de caracterizar las poblaciones fúngicas, en particular las especies potencialmente micotoxigénicas, que pueden contaminar los granos de maíz almacenados en silos bolsa con un contenido de humedad superior ... -
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 ... -
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 ... -
Infection with Spiroplasma kunkelii on temperate and tropical x temperate maize in Argentina and development of a tool to evaluate germplasm
(Springer, 2021-11-30)Corn stunt disease is a disease that extends from the southern United States to Argentina and is one of the most important diseases in warm subtropical areas of the continent, periodically causing yield reductions in maize. ... -
Natural control of corn postharvest fungi Aspergillus flavus and Penicillium sp. using essential oils from plants grown in Argentina
