Deep Learning Solutions for Soybean Leaf Infestation: A VGG19-Based Approach

After all, soybean crops are an essential constituent in world agriculture. These plants generally become easy prey to attacks by pests like Diabrotica speciosa and caterpillars. The early detection of these attacks is pretty significant in reducing the damage from an economic point of view as well as an ecological one. This present study has been motivated by the above facts, proposing a newer deep learning-based solution using a transfer-learning approach with VGG19 CNN for efficient classification of soybean leaf images. In this work, we adopt the pre-trained VGG19 architecture for detecting pests infestation in soybean leaves and perform fine-tuning specific to the problem. In this work, employing transfer learning from VGG19 means utilizing the deep features learned from large-scale image datasets for adaptation in the specialized context of agricultural pest detection. This approach not only improves the model’s accuracy but also reduces the dependency on huge amounts of training data, which is usually a bottleneck in agricultural applications. We test the performance of our model on a very challenging dataset of soybean leaf images, which yields a balanced accuracy of 99.5% on previously unseen test data.The contribution of this work can be both theoretical and practical. Theoretically, the study advances deep learning applications in plant pathology, showing how effective transfer learning will be in a new domain. In practice, our model is a potent tool for early detection of pest infestations that permits interventions in time and avoids huge economic and environmental losses.
