The need to understand the fate of pesticides in the environment has necessitated the development of analytical methods for the determination of residues in environmental media. Adoption of methods utilizing instrumentation such as gas chro-matography/mass spectrometry (GC/MS), liquid chromatography/mass spectrometry (LC/MS), liquid chromatography/tandem mass spectrometry (LC/MS/MS), or enzyme-linked immunosorbent assay (ELISA) has allowed the detection of minute amounts of pesticides and their degradation products in environmental samples. Sample preparation techniques such as solid-phase extraction (SPE), accelerated solvent extraction (ASE), or solid-phase microextraction (SPME) have also been important in the development of more reliable and sensitive analytical methods.

Gerhold et al. (9) developed research techniques to Identify the biochemical metabolite which conditioned resistance. They used the same plant materials that had been Included In Winner s genetic studies and Stark s research. All plants were grown from seed and were maintained without the use of pesticides. Included In their study was a resistant parent, a homozygous recessive susceptible parent, and their hybrid. In addition, they tested a susceptible parent which had one dominant locus for resistance. Basically their technique Involved the collection of exudate and subsequent analysis by gas- and high-performance-liquid chromatography, mass spectrometry, and nuclear magnetic resonance (NMR) spectroscopy.
