| Abstract/Contents: | "Spring dead spot (SDS) is a monocyclic, soil borne disease that affects the rhizomes and stolons of bermudagrass and is more severe in areas with an extended dormancy period, such as the transition zone. Colloquial information shared amongst turfgrass managers suggests that this disease tends to accumulate on north facing slopes and could also be more severe in low lying areas. This research aims to quantify the influence of the local topography and other related environmental factors on the localization of SDS in golf course fairways. State lidar data was combined with SDS locations identified from aerial imagery of 16 fairways across 3 locations throughout the state of Virginia. The slope, aspect (compass direction), annual sunlight, and landform shape of each portion of each fairway was calculated using ArcGIS Pro. Locations of SDS were sampled for these factors in ArcGIS Pro and compared to a random array of points within the same fairways. Topography and other related factors were analyzed using a nominal logistic fit in JMP Pro 16 between SDS and random points and while differences in all features were significant (p≤0.020), combined they only account for approximately 1.2% of the variance between the samples. These data suggest that local topography is among the multitude of factors that contribute to SDS epidemics, but that these features alone do not dictate development." |
