Abstract：Toachieverapididentificationofmaizeleafspotdisease，thedetectionperformanceoftheimprovedYOLOv8modelwasoptimizedbyintegratingtheGlobalAtentionModule（GAM），Slim-Necklightweightmodule，andInner-CIoUlossfunction.Compared with the original YOLOv8 model，the improved YOLOv8 model（GAM + Slim-Neck+Inner-CIoU）showed increases of 4.15% in Precision， 5.51% in Recall， 3.91% in mAP @ 0.5，and 11.35% in mAP @[0.5： 0.95]，while the number of parameters and detection time decreased by10.39% and 3.42% ，respectively. The improved YOLOv8 model outperformed other models（YOLOv3，YOLO v5 ，YOLO v6 ，and Faster R-CNN） in Precision，Recall，mAP @ 0.5，and mAP ，while also demonstrating significant advantagesinparameterquantitynddetectiontime，combining higheficiencywithlightweightcharacteristics.TheimprovedYOLOv8model eficientlycaurediticaliforation，fullyitegatedultdimesioalatures，ndratioallloatedomputatioalrouces，thereby enhancing recognition accuracy.
