| Abstract/Contents: | "Green kyllinga (Kyllinga brevifolia Rottb.) is a common and problematic weed in managed turfgrass systems. The growth habit and morphology of this species create ununiform appearance and rough surface characteristics in golf courses. Once established, green kyllinga may spread rapidly, making it difficult to control. Site-specific treatment using a remotely piloted aerial application system (RPAAS) may be an effective tool for controlling green kylllinga. Additionally, aerial RGB images captured using an Unmanned Aerial System (UAS) can be utilized for weed detection and subsequent treatment using the RPAAS. An experiment was conducted in 2021 at Briarcrest Golf Course in Bryan, TX to investigate two objectives: 1) detect green kyllinga from UAS-based aerial RGB imagery, and 2) evaluate the effectiveness of using an RTK-GPS guided RPAAS for site-specific herbicide treatment of green kyllinga in golf course fairways. Treatments included 1) an RPAAS-based herbicide application with weeds located using manually obtained geo-coordinates, 2) an RPAAS-based herbicide application with weeds located based on image analysis derived geo-coordinates, 3) herbicide application using a backpack sprayer, and 4) an untreated check. Sulfosulfuron (Certainty®) herbicide was used in the experiment for the aerial and ground applications. First, the accuracy of RPAAS targeting green kyllinga patches based on exact coordinates obtained through manual recording was evaluated. Additionally, visible plant injury was recorded at 4 weeks after treatments, and efficacy between the RPAAS treatments and conventional backpack application were compared. The overall accuracy of green kyllinga detection using image analysis was 78%. Compared to backpack applications, the efficacy of aerial applications based on weeds detected using image analysis was 12% lower. No differences were observed between the backpack and the RPAAS-based application with weeds located manually, suggesting that further improvements are necessary with the weed detection model used here. This experiment provided necessary directions for further improving the detection accuracy for green kyllinga, and demonstrates the promise of using RPAAS for site-specific weed management in turfgrass systems." |
