Researchers from the National Institute of Agricultural Technology (INTA), the National Scientific and Technical Research Council (CONICET), and the University of Buenos Aires (UBA) have developed a plant extract with antifungal properties that could soon be used in the agricultural industry.
The research focuses on a native tree species, Peltophorum dubium, commonly known as Ibirá Pitá. This tree’s extract has shown promising results in controlling Aspergillus flavus, a fungus that produces mycotoxins and affects stored grains, leading to economic losses and health risks.
The team of researchers, led by Lucilda Di Ciaccio from INTA and Renée Fortunato from the Darwinion Institute, have conducted extensive studies on the Ibirá Pitá extract. They found that it effectively inhibits the growth and development of Aspergillus flavus, particularly by targeting the fungal cell wall.
The researchers emphasize the potential of this natural product to replace or complement synthetic fungicides, offering a more sustainable and environmentally friendly approach to grain storage. The extract has demonstrated antifungal activity both in its native region (the Chaco region) and in areas where it has been introduced (the Pampean region), with greater promise in its native habitat.
The next step in the research is to develop a prototype that can be transferred to the agro-industrial sector, particularly for post-harvest grain management. This development aims to promote sustainable and socially inclusive economic management of the Ibirá Pitá resource while ensuring the conservation of its wild genetic resources and habitat.
The researchers believe that this natural antifungal agent could offer significant benefits for human and animal health, as well as for the environment. It can be used directly or in combination with existing synthetic fungicides, providing a more comprehensive approach to controlling fungal contamination in stored grains.
