Abstract/Contents:"Small unmanned aerial systems (sUAS) provide rapid and inexpensive aerial imagery of large acreage. Advances in the utilization of this digital technology provide opportunities to improve site-specific turf management and maximize the efficiency for cultural and chemical inputs on turf. An example of successful implementation of aerial imagery is our recent advancement in managing spring dead spot (SDS), a reoccurring disease of bermudagrass (Cynodon spp.). Disease incidence maps created with aerial imagery can help target site-specific fungicide applications based on geographic distribution to limit total pesticide usage. Digital image analysis (DIA) can improve decision making in identifying disease incidence, accuracy, and precision of fungicide applications. Research objectives in our studies included development of methods to map, analyze, and quantify SDS epidemics, while evaluating the effectiveness of site-specific fungicide applications. Aerial DIA was used to create disease incidence maps in spring 2016 and 2017 from five 'Vamont' bermudagrass fairways with a history of SDS. Treatments were arranged in a completely randomized design across twenty replicated 33 m2 plots to include 1) untreated 2) full-coverage tebuconazole (1.2 kg ai ha-1), 3) full-coverage penthiopyrad (1.07 kg ai ha-1), and 4) site-specific penthiopyrad (1.07 kg ai ha-1.) Fall treatments were initiated when soil temperatures reached 21Ā°C. Site-specific treatments reduced fungicide usage by 51% in 2016 and 65% in 2017 while providing statistically equivalent suppression when compared to full-coverage plots. This research demonstrates how aerial data acquisition, DIA, and GPS technologies may be used collectively to provide a practical impact on turf management and serve as a template for additional development of site-specific practices."
