Abstract
An analytical method for a fungicide, (E)-4-chloro-α, α, α-trifluoro-N-(1-imidazole-1-yl-2-propoxyethylidene)-o-toluidine (triflumizole), and its metabolite 4-chloro-α, α, α-trifluoro-N-(1-amino-2-propoxyethylidene)-o-toluidine, in crops is described. These compounds in crops are extracted with methanol and then cleaned by liquid-liquid partition and column chromatography. Determinations were performed by both high performance liquid chromatography and gas chromatography. The detection limit was set at 0.02ppm. The recoveries ranged from 72 to 101%.
