In this context, this paper aims to propose a methodology for the classification of multiple pathologies related to different plant species. Initially, this methodology involved the image processing and the generation of ten new databases, varying between 50 and 66 classes with greater representation. After training the models (VGG16, RestNet101v1, ResNet101v2, ResNetXt50, and DenseNet169), a comparative study was conducted based on widely used classification metrics, such as test accuracy, f1-score, and area under the curve. To attest the significance of the results, Friedman&#8217;s nonparametric statistical test and two post-hoc procedures were performed, which demonstrated that ResNetXt50 and DenseNet169 obtained superior performances when compared with VGG16 and ResNets.<\/p>\n<p><strong>Keywords:<\/strong> Convolutional neural networks, Plant Diseases, Database, Classification, Deep Learning.<\/p>\n<p><strong>DOI code:<\/strong> <a href=\"http:\/\/dx.doi.org\/10.21528\/lnlm-vol18-no2-art3\">10.21528\/lnlm-vol18-no2-art3<\/a><\/p>\n<p><strong>PDF file:<\/strong> <a href=\"https:\/\/sbia.org.br\/lnlm\/wp-content\/uploads\/sites\/4\/2021\/01\/vol18-no2-art3.pdf\">vol18-no2-art3.pdf<\/a><\/p>\n<p><strong>BibTex file:<\/strong> <a href=\"https:\/\/sbia.org.br\/lnlm\/wp-content\/uploads\/sites\/4\/2021\/01\/vol18-no2-art3.bib\">vol18-no2-art3.bib<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Michel Costa , Vanessa Rezende , Cledisson Martins &amp;
