| Abstract/Contents: | "Fenamiphos, the only nematicide registered for nematodes in golf greens, will no longer be available for use after May 2005. Many "softer" alternatives to fenamiphos are available commercially but have not been efficacious in our trials. We have noticed that high populations of nematodes in putting greens often decline after several years without nematicide treatment. Pasteuria spp. are known to parasitize many species of nematodes and may play a role in suppression of nematode populations. For these reasons, we began an investigation of Pasteuria as a natural suppressant of nematodes in golf greens. Four golf greens with Pasteuria-infested root-knot nematode (Meloidogyne graminis) and three greens with stunt nematode (Tylenchorhynchus spp.) were evaluated for nematode populations and percent of Pasteuria infestation. To ensure the estimation of nematode population and percent Pasteuria infestation within 95% C.I., the number of soil cores necessary was determined. Root-knot nematodes were found to be highly aggregated, 70 to 100 soil cores were necessary to estimate the population. However, only 16 to 43 soil cores were necessary to estimate the percent of root-knot nematode infested with Pasteuria. Distributions of stunt populations were also aggregated but less than root-knot. Nine to 15 soil cores were necessary to estimate the stunt population and 10 to 27 soil cores were necessary to estimate the percent of nematodes infested with Pasteuria. The relationship of Pasteuria to root-knot and stunt was found to be inversely correlated with R2 values equal to 0.75 and 0.44 respectively. Further studies to monitor population dynamics of Pasteuria and plant parasitic nematodes in golf greens are underway." |
