Plant diseases pose significant challenges to farmers and the agricultural sector at large. However, early detection of plant diseases is crucial to mitigating their effects and preventing widespread damage, as outbreaks can severely impact the productivity and quality of crops. With advancements in technology, there are increasing opportunities for automating the monitoring and detection of disease outbreaks in plants. This study proposed a system designed to identify and monitor plant diseases using a transfer learning approach. Specifically, the study utilizes YOLOv7 and YOLOv8, two state-of-the-art models in the field of object detection. By fine-tuning these models on a dataset of plant leaf images, the system is able to accurately detect the presence of Bacteria, Fungi and Viral diseases such as Powdery Mildew, Angular Leaf Spot, Early blight and Tomato mosaic virus. The model's performance was evaluated using several metrics, including mean Average Precision (mAP), F1-score, Precision, and Recall, yielding values of 91.05, 89.40, 91.22, and 87.66, respectively. The result demonstrates the superior effectiveness and efficiency of YOLOv8 compared to other object detection methods, highlighting its potential for use in modern agricultural practices. The approach provides a scalable, automated solution for early any plant disease detection, contributing to enhanced crop yield, reduced reliance on manual monitoring, and supporting sustainable agricultural practices.
植物病害给农民和整个农业部门带来了重大挑战。然而,早期发现植物病害对于减轻其影响和防止广泛破坏至关重要,因为病害爆发会严重影响作物的产量和质量。随着技术的进步,实现植物病害爆发监测和检测自动化的机会越来越多。本研究提出了一种利用迁移学习方法来识别和监测植物病害的系统。具体而言,该研究使用了YOLOv7和YOLOv8这两种目标检测领域的先进模型。通过在植物叶片图像数据集上对这些模型进行微调,该系统能够准确检测出白粉病、角斑病、早疫病和番茄花叶病毒等细菌、真菌和病毒病害的存在。使用包括平均精度均值(mAP)、F1分数、精确率和召回率在内的多个指标对模型性能进行评估,其值分别为91.05、89.40、91.22和87.66。结果表明,与其他目标检测方法相比,YOLOv8具有卓越的有效性和效率,凸显了其在现代农业实践中的应用潜力。该方法为早期植物病害检测提供了一种可扩展的自动化解决方案,有助于提高作物产量、减少对人工监测的依赖,并支持可持续农业实践。
