| Abstract/Contents: | "We conducted a study to determine the relationship between turfgrass management intensity and natural occurrence of entomopathogenic nematodes (EPNs). We surveyed for EPNs on putting greens, fairways, and rough areas - three distinct surface types on golf courses that are managed with different intensities. We collected 159 soil samples from putting greens, contiguous fairways, and rough areas from 19 golf courses in Ohio, USA. Nematodes were recovered from soil samples using the insect baiting technique. We also analyzed the soil samples for texture, organic matter, pH, phosphorus, calcium, magnesium and potassium. We used principal components analysis and Pearson correlation to determine the relationship between nematode occurrence and the measured parameters. Surface type was the most important factor in predicting EPNs occurrence. Putting greens differed significantly from fairways and rough areas in the number of EPN-positive sites. No EPNs were recovered from putting greens but were recovered from 43% of the fairways and 57% of the rough areas. Putting greens also differed significantly from fairways and rough areas in organic matter, pH, calcium, and phosphorus. The fairways and rough areas did not however differ in number of EPN-positive sites and measured soil parameters. Presence of EPNs correlated significantly, although weakly, with sand, silt, phosphorus, organic matter, and magnesium content, but not with clay, pH, calcium, and potassium. Nematode isolates were identified as Heterorhabditis bacteriophora, Steinernema carpocapsae, and S. glaseri. This suggests that EPNs are more likely to occur in less intensively managed sites that receive fewer inputs and have relatively high sand, and moderate silt, organic matter, phosphorus, and magnesium content." |
