| Abstract/Contents: | "Previous research has shown plant-pollutant bioremoval capacity may differ across species and/or pesticides. Phytoremediation of pesticides has been minimally investigated with plant species adapted to environmental conditions common to the southeast United States. Therefore, research is needed to expand upon current knowledge to identify plant species best suited to mitigate pesticide off-target transport for selection when establishing and/or renovating riparian buffers or stormwater wetland areas in urban and rural settings. To address this knowledge gap, greenhouse research was conducted evaluating atrazine (herbicide), azoxystrobin (fungicide) and imidacloprid (insecticide) bioremoval capacity of three terrestrial plant species [switchgrass (Panicum virgatum), blueflag iris (Iris versicolor), and broomsedge (Andropogon virginicus)]. These plant species were chosen based on prior trace element phytoremediation studies and the plants' tolerance to commonly used herbicides. Plants were established in unique containers (506.7 cm2) consisting of a Candor sand (92, 4, 4% sand, silt, and clay, respectively) and treated with atrazine (2 kg ai ha-1), azoxystrobin (0.5445 kg ai ha-1), or imidacloprid (0.4 kg ai ha-1). At 28, 56 or 112 days after treatment (DAT) unique plants were destructively harvested and sectioned into above- and below-soil surface portions for subsequent residue analysis. Additionally, four soil cores were collected form each container to a depth of 7.5 cm and segmented into 0 to 2.5, 2.5 to 5.0 and 5.0 to 7.5 cm soil depths for residue analysis. Results suggest switchgrass, blueflag iris, and broomsedge continuously remediate all three pesticides through 112 DAT. Azoxystrobin was found to be remediated at a higher rate than atrazine or imidacloprid. Information from this research will aid in the construction of a mitigation plan for urban and rural landscapers to minimize the possible risk of off-target pesticide movement." |
