According to the FAO, around 660 million people might still suffer from chronic hunger in 2030. Our food production must dramatically increase to meet the ever-growing demand of the population. However, plant diseases are a major reason behind our food insecurity, and it is estimated to rise due to globalization, global warming, etc. Thus, Plant disease classification is a vital step in controlling plant diseases. Traditionally, this was achieved using direct and indirect methods like RT-PCR or thermography which are expensive, need a trained expert, and don’t provide a real-time diagnosis. Diseases in plants are caused by various pathogens and identifying them through Machine learning is a major focus of this study as not much work has been done in this field of plant health monitoring and early detection of the pathogen can give insights on how to best combat the infestation. It can also be used to quickly identify the pathogen if a new plant disease is found, and for breeding more pathogen-resistant plants without the need for a trained expert. In this study, we have focused on 5 crop and their disease-causing pathogens, namely Apple Scab in apples, Early Blight in potato, Citrus Greening in oranges, Bacterial Spot in peaches, Late Blight in tomatoes, Spider Mites in Tomatoes, Mosaic Virus in Tomatoes and Yellow Leaf Curl Virus in Tomatoes. We have used computer vision techniques to extract features of the infected leaves from the PlantVillage dataset and achieved promising results using various Supervised Machine Learning techniques such Random Forest, SVM, Naive Bayes, and KNN to classify the pathogen type. The maximum accuracies achieved using Random Forest was 96.6% for Bacteria, 100% for Fungi, 100% for Mites, 93.3% for Mold, and 80% for Viruses. Similarly, for SVM, the maximum accuracies achieved were 96.6% for Bacteria, 93.3% for Fungi, 96.6% for Mites, 100% for Mold, and 93.3% for Viruses. The maximum accuracies achieved using Naive Bayes was 20% for Bacteria, 63.3% for Fungi, 43.3% for Mites, 93.3% for Mold, and 3% for Viruses, and lastly, The maximum accuracies achieved using KNN was 80% for Bacteria, 36.6% for Fungi, 46.6% for Mites, 46.6% for Mold, and 16.6% for Viruses.
