Plant diseases are a persistent threat to the global agricultural economy, compromising food supply and security. Accurate and early diagnosis is vital for effective agricultural management. This study addresses this gap by introducing a better approach for identifying plant diseases in leaves: the Integrated Hybrid Attention-Based One-Class Neural Network (ABOCNN) System. The system uses deep learning and domainspecific information, as well as powerful neural networks and attention processes, to extract features unique to a certain ailment while excluding irrelevant data. By dynamically focusing on prominent areas in leaf images, the proposed methodology obtains an impressive 99.6% accuracy, beating both traditional approaches and cutting-edge deep-learning approaches by an average of 12.7%. The practical use of this strategy has a significant influence on crop yield and agricultural sustainability. Attention maps increase interpretability and help individuals comprehend more fully how decisions are made. The system, written in Python, is precise, scalable, and adaptable, making it a helpful tool for a wide range of agricultural applications combining multiple plant species and disease classifications. With an incredible 99.6% accuracy rate, the Integrated Hybrid ABOCNN Technology provides an innovative method for diagnosing plant diseases, outperforming conventional approaches by 12.7%. Attention maps increase interpretability and give important information about the model's decisionmaking processes.
