In order to quickly and accurately identify crop diseases, help farmers to control crop diseases in time, and reduce crop losses. Inspired by the application of convolutional neural networks in image identification, we propose a lightweight crop disease image identification model based on attentional feature fusion named DSGIResNet_AFF, which introduces self-built lightweight residual blocks, inverted residuals blocks, and attentional feature fusion modules on the basis of ResNet18. We apply the model to the identification of rice and corn diseases, and the results show the effectiveness of the model on the real dataset. Additionally, the model is compared with other convolutional neural networks (AlexNet, VGG16, ShuffleNetV2, MobileNetV2, MobileNetV3-Small and MobileNetV3-Large), and the experimental results show that the accuracy, sensitivity, F1-score, AUC of the proposed model DSGIResNet_AFF are 98.30%, 98.23%, 98.24%, 99.97%, respectively, which are better than other network models, while the complexity of the model is significantly reduced (compared with the basic model ResNet18, the number of parameters is reduced by 94.10%, and the floating point of operations(FLOPs) is reduced by 86.13%). The network model DSGIResNet_AFF can be applied to mobile devices and become a useful tool for identifying crop diseases.<\/jats:p>","DOI":"10.3390\/s22155550","type":"journal-article","created":{"date-parts":[[2022,7,26]],"date-time":"2022-07-26T00:17:27Z","timestamp":1658794647000},"page":"5550","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Development of a Lightweight Crop Disease Image Identification Model Based on Attentional Feature Fusion"],"prefix":"10.3390","volume":"22","author":[{"given":"Zekai","family":"Cheng","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology, Anhui University of Technology, Ma\u2019anshan 243032, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4608-3094","authenticated-orcid":false,"given":"Meifang","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Anhui University of Technology, Ma\u2019anshan 243032, China"}]},{"given":"Rong","family":"Qian","sequence":"additional","affiliation":[{"name":"Institute of Agricultural Economy and Information, Anhui Academy of Agricultural Sciences, Hefei 230031, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6857-9413","authenticated-orcid":false,"given":"Rongqing","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Anhui University of Technology, Ma\u2019anshan 243032, China"}]},{"given":"Wei","family":"Dong","sequence":"additional","affiliation":[{"name":"Institute of Agricultural Economy and Information, Anhui Academy of Agricultural Sciences, Hefei 230031, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,25]]},"reference":[{"key":"ref_1","first-page":"313","article-title":"Research Progress on Image Recognition Technology of Crop Pests and Diseases Based on Deep Learning","volume":"50","author":"Jia","year":"2019","journal-title":"Trans.
