Abstract/Contents: | "The turfgrass industry is an estimated $40 billion industry with approximately $175 million spent on fungicide applications annually. Recent research demonstrated 24 to 34% of the liquid formulation of azoxystrobin could be removed in turfgrass clippings following a single mowing event one day after application on turfgrass maintained under recommended lawn conditions. Irrigation is typically applied immediately following fungicide applications when targeting soil-borne pathogens, however there is little research elucidating the effect of post application mowing and irrigation timing on the environmental fate of fungicides used for soil borne disease management. The objectives of this study are to determine the effect of various mowing Irrigation schedulingand irrigation timings on fungicide residual in clippings and the dissemination of these fungicides through the soil profile. A single fungicide application of pyraclostrobin was administered and experimental units received either .635 cm post-application irrigation immediately following application or .635 cm post-application 6 hours after application. Turfgrass clippings were then harvested immediately following respective irrigation treatments, 1 day after fungicide treatment (DAFT), or 3 DAFT. Cores were harvested using a 10.80-cm diameter cup cutter at 0, 1, 3, 7, and 14 DAFT. Each core was sectioned into four subsamples including remaining above ground vegetation, 0 to 2.54-cm, 2.54 to 5.08-cm, and 5.08 to 7.62-cm depths. Turfgrass clippings, remaining above ground vegetation, and soil subsamples were homogenized and subjected to liquid chromatography mass spectrophotometry. Samples are currently being analyzed to determine the movement and environmental fate of these compounds following mowing and irrigation timings." |
