Abstract

Potatoes are one of the world’s most important food crops, but they are vulnerable to various diseases that can reduce yield and quality. Many farmers in Nigeria still rely on manual inspection and random chemical application, which are often ineffective. This study introduces a Potato Plant Leaf Disease Diagnosis System that uses deep learning to improve disease detection. The system is powered by the EfficientNetB7 Convolutional Neural Network (CNN), a highly accurate model for image classification. The model was trained on a dataset of potato leaf images and achieved 98% accuracy on the test set and 97.5% validation accuracy, proving its reliability. The system is available as a web application, allowing farmers to upload or capture leaf images, get a diagnosis, and receive treatment advice. By providing a fast and accurate diagnosis, the system helps farmers make better decisions, improve crop health, and reduce losses.
