Growers struggle with fungal diseases that infect grapevine nurseries, reducing the quality of planting material. Researchers tested electrolyzed water—a solution made from salt and water using electricity—as a sustainable treatment for infected grapevine cuttings. Laboratory tests showed the treatment effectively killed fungal spores and reduced fungal growth. Field trials at a commercial nursery confirmed that treating cuttings with electrolyzed water reduced certain grapevine diseases without harming plant growth.
