This technology concerns Streptomyces spp. strains, isolated from different marine biotopes, able to inhibit the growth of Gnomoniopsis smithogilvyi (Gs). This fungus is the causal agent of chestnut brown rot responsible for damages in post-harvest fruits, and of wood cankers in the chestnut tree - responsible for massive losses in the chestnut sector. The actinobacterial extracts, as well as the corresponding strains, presented an excellent activity against Gs. These strains can be used in integrated and organic agriculture for biological control and integrated Gs management.
The fungusGnomoniopsis smithogilvyi(Gs) is responsible for brown chestnut rot that damages the fruit after harvest and causes wood cankers in the chestnut tree - responsible for massive losses in the chestnut sector.
There are currently limited options to fight this fungus, which consists only of synthetic fungicides that have a significant impact on the environment, as well as on human and animal health – which for this reason will be banned.
The technology provides a solution that uses marine actinobacteria strains, fromStreptomyces genus, or its spores, as a fungicide capable of inhibiting the growth of the Gs fungus.
The extracts of theStreptomyces strains presented a significant anti-Gs activity comparable to or higher than the inhibition caused by Fluconazole and Amphotericin, two common antifungal agents.
This technology can sustainably control Gs, which can be used in integrated and organic agriculture for biological control.
