Tomato leaf diseases pose a major threat to agricultural productivity and global food security. Early detection is essential to minimize crop loss and improve yield quality. In recent years, artificial intelligence (AI), particularly deep learning, has emerged as a powerful tool for automated plant disease detection using image-based approaches. This paper presents a comprehensive systematic review of AI-based techniques for tomato leaf disease classification, covering convolutional neural networks (CNNs), transfer learning methods, transformer-based architectures, and hybrid models. Furthermore, the study critically examines the role of explainable artificial intelligence (XAI) techniques, including Grad-CAM, LIME, and SHAP, in enhancing model transparency and interpretability. A detailed evaluation of widely used datasets, such as PlantVillage and real-world field datasets, is conducted to assess model generalization. Comparative analysis highlights the strengths and limitations of different approaches. Key challenges, including dataset bias, lack of real-world robustness, and computational constraints, are discussed. Finally, future research directions focusing on lightweight architectures, edge AI, and multimodal learning are proposed to bridge the gap between research and practical agricultural deployment. The review reveals that CNN-based models achieve up to 99% accuracy on benchmark datasets; however, their performance significantly decreases under real-world conditions due to dataset bias and environmental variability. These findings highlight the need for robust and generalizable AI solutions for real-world agricultural deployment.
KEYWORDS
This paper presents a comprehensive systematic review of AI-based approaches for tomato leaf disease classification. Deep learning models, particularly CNN-based architectures, have demonstrated remarkable success in achieving high classification accuracy. However, their performance is often limited by dataset bias and lack of generalization to real-world conditions. The integration of explainable AI techniques has improved model transparency and interpretability, addressing one of the key challenges in deploying AI systems in agriculture. Despite these advancements, several issues remain, including limited availability of real-world datasets, computational constraints, and challenges in model deployment. Future research should focus on developing robust, lightweight, and interpretable models that can operate effectively in real-world environments. The integration of edge AI, multimodal learning, and advanced explainability techniques will play a crucial role in advancing the field. Overall, AI-based tomato leaf disease detection systems have significant potential to enhance agricultural productivity and sustainability. However, bridging the gap between laboratory performance and real-world deployment remains a critical challenge that must be addressed in future research.
