  1. Biology, Epidemiology, and Management of Spring Dead Spot of Bermudagrass

    Spring dead spot (Ophiosphaerella spp.) (SDS) of bermudagrass (Cynodon dactylon (L.) Pers. x transvaalensis Burtt Davy) is one of the most challenging diseases in the United States transition zone. Six projects were conducted from 2019 to 2022 to better understand the environmental, edaphic, and …

  2. Investigating Spring Dead Spot Management via Aerial Mapping and Precision-Guided Inputs

    Spring dead spot (SDS) is the most destructive disease of bermudagrass (Cynodon spp.) in Virginia. SDS infects bermudagrass in the fall with symptoms appearing in the spring when dormancy breaks. Patches are sporadically distributed but generally reoccur in the same location. Chemical control …

  3. Utilizing spring dead spot mapping to assess precision management strategies, topographical epidemiology, economic opportunities

    Spring dead spot (SDS), a monocyclic, soil-borne disease caused by Ophiosphaerella spp., affects the rhizomes and stolons of bermudagrass (Cynodon dactylon L. Pers), and is particularly severe in regions with extended dormancy, such as the transition zone. This research evaluates three aspects of …

  4. Identification of Disease Stress in Turfgrass Canopies Using Thermal Imagery and Automated Aerial Image Analysis

    … The second project attempted to isolate spring dead spot from aerial imagery of bermudagrass golf course fairways using a Python script. Aerial images from unmanned aerial vehicle flights were collected from four fairways at Nicklaus Course of Bay Creek Resort in Cape Charles, VA. …

  5. Quantifying Field Variability Effects on Surface Performance and Athletes

    … U.S. transition zone, turfgrass stressors like spring dead spot (SDS; Ophiosphaerella spp.) and winter injury are common on bermudagrass (Cynodon dactylon) athletic fields, yet limited research has evaluated how variability from these stressors affects field performance or safety. Existing …
