Abstract :Bacterial and fungal leaf diseases significantly impact the productivity of agricultural, which causing annually billions of dollars in crop losses and threatening global food security. Conventional detection methods even though effective, but they are labor intensive, consuming more time, and inappropriate for real time applications or large-scale ones. In order to address the limitations of other studies, this study proposes an AI solution that using a fine-tuned ResNet50 model trained on the PlantVillage dataset to classify the plant leaves as Healthy, Bacterial, or Fungal (Mold). The model was optimized using TensorFlow Lite and deployed on a Raspberry Pi 4, achieving 87% accuracy, a recall of 86%, and inference speeds around 1.2 to1.5 seconds per image. To enhance the overall generalization, the data augmentation techniques were applied which including rotation, flipping, and scaling. For early disease detection in agricultural and environmental applications, this research provides a scalable and a cost effective. Compared to traditional methods and other systems, this study provides faster inference speeds and lower costs, making it ideal for designs with limited resource.
