Abstract: Tea diseases, including brown and grey blight, result in significant yield and quality losses, especially in Longjing tea production. Traditional detection methods are prone to errors, while existing deep learning models often struggle to be robust in natural field conditions. To address these challenges, an improved lightweight detection model, Asymmetric Multi-level mechanism, Dynamic Snake convolution, SIoU loss function-YOLO (ADS-YOLO), was developed and validated. In the method, a dataset comprising 5694 smartphone-captured images of tea leaves was established under natural lighting. Enhancements were implemented in the YOLO11n baseline algorithm through the incorporation of the SIoU loss function for better bounding box regression, dynamic snake convolution (DSC), which realizes adaptive feature extraction based on the dynamic spatial context, and an Asymmetric Multi-level (AML) mechanism, which achieves lightweight feature fusion via adaptive multi-scale design. The results showed that ADS-YOLO achieved a precision of 0.935 and a recall of 0.870, compared to 0.894 and 0.818, respectively, using the baseline YOLO11n. Importantly, ADS-YOLO demonstrated a real-time performance of 137.1 FPS, coupled with reduced computational costs. ADS-YOLO improved mAP@0.5 by 6.4% compared with YOLOv5n and achieved up to 44.6% higher accuracy than YOLOv7t. In conclusion, ADS-YOLO achieved high accuracy, providing a scalable solution for real-time crop health monitoring and sustainable, precision agriculture for tea prodution.
