A collaboration between the University of Concepción and the Ferrero Hazelnut Company aims to study the control of bacterial blight and powdery mildew in European Hazelnut, a crop grown in southern Chile. The research involves evaluating the effectiveness of conventional and organic fungicides, with a focus on minimizing environmental impact and reducing residue. The partnership also includes monitoring pathogen spores and using molecular tools for early detection of diseases, with plans to continue this season. The results of this research could significantly improve hazelnut production in Chile.
