Identification and Classification of Leaf Diseases in Turmeric Plants

Plant disease identification is the most important sector in agriculture. Turmeric is one of the important\ud rhizomatous crops grown in India. The turmeric leaf is highly exposed to diseases like rhizome rot, leaf spot,\ud and leaf blotch. The identification of plant diseases requires close monitoring and hence this paper adopts\ud technologies to manage turmeric plant diseases caused by fungi to enable production of high quality crop yields.\ud Various image processing and machine learning techniques are used to identify and classify the diseases in\ud turmeric leaf. The dataset with 800 leaf images of different categories were pre-processed and segmented to\ud promote efficient feature extraction. Machine learning algorithms like support vector machine, decision tree and\ud naïve bayes were applied to train the model. The performance of the model was evaluated using 10 fold cross\ud validation and the results are reported
