Abstract

Two general procedures are outlined for residue determination of pyrethroid derivatives of chrysanthemic acid on wheat, wheat milling fractions, polished rice, maize, sorghum, oats and barley. Although limits of detection ranged upwards from 0.02 μg, residues in the range 0.1–4 ppm were readily analyzed on inexpensive equipment after suitable clean-up procedures. Wheat treated some months before analysis with bioresmethrin was analysed by the two general procedures for derivatives of chrysanthemic acid, and also by two procedures specific for analysisof bioresmethrin. Results from all four procedures were comparable. One of the procedures for identification of chrysanthemic acid also enabled identification of pyrethroid derivatives of chrysanthemum dicarboxylic acid and 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopro-panecarboxylic acid. Thus a wide range of commodities can be screened for the presence of commercial pyrethroids. In addition, analytical studies on individual pyrethroids can be performed by use of a general method
