The application of copper nanoparticles to fight against grapevine trunk diseases (GTDs) is a practice that has been identified in a vineyard from Galicia, in Spain. Periodic applications (via trunk injection) of aqueous solution of copper nanoparticles in 26 years oldAlbariño vines damaged by Esca are complemented by folia treatments, spraying of a mixture of copper nanoparticles and an elicitor based on amino acids from porcine blood.
Results have not been observed yet, since 2016 has been the first year of application no results are availables
