The overall objective of this research project is to determine whether the presence of plants at pesticide-contaminated sites enhances the dissipation of pesticide wastes as a result of increased degradation by microbial communities in the rhizosphere.
Experiments will be conducted to address these specific hypotheses: (1) rhizosphere soil from Kochia sp. growing in soil contaminated with pesticides will degrade high concentrations of a herbicide mixture more rapidly than similar soil not previously exposed to such contamination; (2) herbicide-resistant plants will increase the bioavailability and degradation of herbicides that have aged in soil; and (3) a rhizosphere effect can be created in subsurface soil from a contaminated site, thus supporting the importance of the rhizosphere effect in rapid degradation of pesticide wastes.
