Nowadays, crop diseases are a crucial problem to the world's food supplies, in a world where the population count is around 7 billion people, with more than 90% not getting access to the use of tools or features that would identify and solve the problem. At present, we live in a world dominated by technology on a significant scale, major network coverage, high-end smart-phones, as long as there are great discoveries and improvements in AI. The combination of high-end smart-phones and computer

... sion via Deep Learning has made possible what can be defined as "smartphone-assisted disease diagnosis". In the area of Deep Learning, multiple architecture models have been trained, some achieving performance reaching more than 99.53% [1] . In this study, we evaluate CNN's architectures applying transfer learning and deep feature extraction. All the features obtained will also be classified by SVM and KNN. Our work is feasible by the use of the open source Plant Village Dataset. The result obtained shows that SVM is the best classifier for leaf's diseases detection.
