Advancements for Improved Plant Disease and Pest Identification: A Survey

Image classification methods are widely applied to the identification of plant pests and diseases. Despite recent innovative efforts in plant pest and disease identification, the vast diversity of plant pest and disease types and long-tail distribution of data continue to pose serious challenges. In this context, we have thoroughly reviewed numerous papers published over the past three years regarding plant pest and disease identification and classification tasks. Our aim is to provide a timely yet not exhaustive overview of the latest advancements in these tasks, and fairly compare the strengths and weaknesses of existing work. To enrich this survey, we provide in-depth analysis and thoughtful discussion on these topics in each subsection, in the hope of providing guidance for subsequent research.
