Abstract：Toaddress the challenges of corn-associated weed detection，such as diverse shapes，dense occusion，complex backgrounds and scale variation，animproved object detection model，WAAP-YOLO，was proposed.First，the backbone was improved byreplacing someconvolutions with wavelet poling convolutions，effectively avoiding aliasingartifacts.Second，an agregatedatentionmechanism wasintroduced toconstructtheC2f-AA module，improving the model'sabilitytoextractwed featuresincomplexbackgrounds.Finall，ASF-P2-Netwas proposed toreplace theoriginal neck network，incorporating the P2 detection head through the scale sequence fusion module，reducing model complexityand significantly improving small object detection performance. Experimental results show that the WAAP-YOLO detection algorithm achieves 97.2% mAP @ （2 0.5， 85.8% mAP@0.5：0.95 ，94. 0% Fl score，and a parameter count of 2.1×106 ，outperforming common object detection models such as YOLOv5s，YOLOv8n，and YOLOvlOn.The proposed model can significantly enhance cornfield weed recognitionacuracy，which providessomereferenceforadvancing theintellgent and sustainable developmentof the

agricultural industry.
