Reducing copper in Sicilian citrus orchards

On Thursday 11th March 2021, researchers from the University of Catania (UNICT) presented the results of trials carried out in the Pedagaggi Sicilian citrus orchards. The results of trials with organic products as alternative to copper were presented to stakeholders, including technicians, advisors, organic producers, representatives of biotech companies and organic farmers. The UNICT research team demonstrated the positive results of the alternative products against emerging fungal pathogens (Colletotrichum spp. and Alternaria spp.) in citrus orchard located in Pedagaggi (Syracuse province).

Stakeholders gathered in the Pedagaggi orchards to see the results of Organic-PLUS trials

Biological alternative products (chitosan, Equisetum, sweet orange essential oils and their mixtures) showed effective reduction of disease incidence comparable to copper compounds. Participants shared their experiences and questions in the use of alternative products in integrated and organic citrus farming systems. The participants greatly appreciated the visit to the field which allowed them to “practically” verify the results of the experiments in the citrus groves of Tarocco cv. Scirè.
