Abstract
This article discusses the application of crop identification and protection technologies in enhancing crop health. Through research and application in key areas such as crop image recognition, pest and disease monitoring and warning systems, crop health monitoring and assessment, smart pesticide spraying and fertilization, as well as biological control and ecological balance, precise monitoring and protection of crop growth conditions have been achieved. The continuous innovation and application of these technologies help reduce damage from pests and diseases, improve crop yield and quality, and promote sustainable development in agriculture.
