Abstract

The existing method for the analysis of 3-tert-butyl-5-chloro-6-methyluracil (terbacil) has been modified so that electron capture gas chromatography may be used for quantitation. The crop extract was applied to a powdered cellulose column, the interferences were eluted with hexane, and the terbacil was subsequently eluted with ethyl acetate. The ethyl acetate fraction may be used for analysis directly.
