Global food security depends on tomato growing, but several fungal, bacterial, and viral illnesses seriously reduce productivity quality, therefore causing major financial losses. Reducing these impacts early, exact diagnosis of diseases. This work provides a deep learning-based ensemble model for leaf disease classification combining MobileNetV2 ResNet50. To improve feature extraction, the models were tweaked by changing their output layers with GlobalAverage Pooling2D, Batch Normalization, Dropout, Dense layers. take use complimentary qualities, maps from both combined. study uses publicly available dataset Kaggle classification. Training 11,000 annotated pictures spanning 10 categories, including bacterial spot, early blight, late mold, septoria spider mites, target yellow curl virus, mosaic healthy leaves. Data preprocessing included image resizing splitting, along an 80-10-10 split, allocating 80% training, 10% testing, validation to ensure balanced evaluation. The proposed 99.91% test accuracy, suggested was quite remarkable. Furthermore, guaranteeing strong performance across all showed great precision (99.92%), recall (99.90%), F1-score 99.91%. With few misclassifications, confusion matrix verified almost flawless even further. These findings show how well learning can automate diagnosis, providing scalable accurate solution smart agriculture. By means intervention agriculture techniques, strategy has potential crop health monitoring, economic losses, encourage sustainable farming practices.

ABSTRACT The rapid development of computer vision technology has provided new technical support for smart agriculture. Vegetable diseases represent a significant threat to agricultural production, with severity that cannot be ignored. However, through scientifically effective prevention and control measures, these negative impacts can significantly mitigated. Intelligent disease detection systems, as advanced methods replacing traditional manual inspection, have become important means developing agriculture improving the efficiency vegetable production management. Nevertheless, is not only time‐consuming labor‐intensive but also faces accuracy limitations, while existing still encounter series challenges when confronting complex backgrounds, diverse manifestations, varying degrees occlusion in real cultivation environments, including insufficient anti‐interference capabilities, limited precision, suboptimal real‐time performance. This research addresses practical data acquisition sample scarcity protected by proposing an innovative strategy implements differentiated augmentation technique combinations different categories samples, enhancing model's resistance environmental interference. Based on integrated concepts machine deep learning, we developed lightweight network named VegetableDet. innovatively combines Deformable Attention Transformer (DAT) YOLOv8n backbone architecture, perception capabilities long‐range feature dependencies. Simultaneously, Channel‐Spatial Adaptive Mechanism (CSAAM) into Neck network, achieving precise localization enhancement key features. To address issue low model convergence efficiency, further designed hierarchical progressive transfer learning training strategy, effectively accelerating adaptation process accuracy. Experimental evaluation demonstrates our custom comprehensive dataset, VegetableDet exhibits excellent performance detecting 30 healthy samples across 5 types, precision (P), recall (R), average (AP) all exceeding 90%, overall mean Average Precision (mAP) reaching 94.31%. powerful adaptability under conditions, providing reliable monitoring diseases, broad application prospects.
