Vegetated Filter Strips (VFSs) are best management practices recommended by the Natural Resource Conservation Service (NRCS) and are located along the perimeter (edge-of-field) of cropland to reduce runoff, sediment, and associated agrochemical transport from agricultural fields. Their major mechanisms include increased infiltration, reduced runoff discharge and velocity, and increased sediment deposition. A study was conducted to generate field scale data for benzovindiflupyr, an SDHI fungicide, that demonstrates the impact of a VFS on benzovindiflupyr transport in a cotton-peanut-cucurbit rotation in a typical southeastern U.S. agricultural setting. This study had two objectives: 1) to determine the fate of runoff transported benzovindiflupyr in a typical southeastern U.S. farm pond (2017 – 2018) with a cropped area to pond area ratio of approximately 10:1; and 2) evaluate 0-, 15-, and 30-ft wide VFS impacts on runoff transported benzovindiflupyr from cropped 21’ x 200’ replicated runoff plots receiving natural precipitation in 2018. Initial residue results for pond water, pond sediment and runoff will be presented.
