This project consistes in the development of the Uzum system for the diagnosis of diseases, pests and nutritional and physiological disorders in four temperate climate fruits: Grapes, Peaches, Strawberries and Apples. The software uses artificial intelligence to quickly diagnose possible disturbances occurring in the orchard, using a simple and direct interface. The knowledge base is generated from information and images provided by experts in each area. The system is being developed initially for web access, but an app for offline use will also be made available.
