Pesticide Residue Analysis -Fate and dissipation of pesticides in soil, runoff water, groundwater, and on plant tissues. Extraction, cleanup and determination of synthetic and botanical insecticides on vegetables. Soil erosion and runoff are some of the major means by which pesticides enter streams, ponds, or lakes. The Water Quality Project at Kentucky State University (KSU) is evaluating best management practices for the growing of vegetable crops on highly erodible land (10% slope).
Insecticides from Wild Tomato - Insects have developed resistance to many, in some cases all, of the synthetic insecticides used for their control. Botanical insecticides offer a partial solution as substitutes for synthetic pesticides, particularly when two or more active components are combined.
Performance of Constructed Wetlands for On-site Wastewater Treatment - Surface and groundwater have become off-site sinks and a pressing environmental problem due to agricultural applications of fertilizers and pesticides. Evidence exists that pesticides and fertilizers can move into shallow aquifers underlying the karstic topography in Kentucky through the root zone due to the presence of open conduits. A major goal of the water quality research at Kentucky State University (KSU) is to provide fertilizer and pesticide fate models that can be used in planning landscape modifications for water quality improvements.
