January
31, 2006 - The California Department of Pesticide Regulation
reports a small increase in pounds of pesticides applied in
2004, but that included a dramatic rise in the use of some nature-friendly
chemicals... "A dramatic increase
occurred in the use of some newer, reduced-risk pesticides such
as spinosad, acetamiprid, pyraclostrobin, methoxyfenozide,
carfentrazone-ethyl, and boscalid,"
DPR analysts reported..." Western

The analytical method involves separate analyses
for parenand its metabolites. The parent is analyzed by GC/electron
capture detection (ECD). The metabolites are derivatized with
boron trifluoride and acetic anhydride for analysis by GC/mass
spectrometry detection (MSD) using selective ion monitoring.
