The metabolism of a new fluorinated fungicide [N-ethyl-N-methyl-4-(trifluoromethyl)-2-(3,4dimethoxyphenyl)benzamide] by Acer pseudoplatanus cells was studied concurrently through the use of 19F NMR and with 14C-labeled compound. Approximately 10 fluorinated compounds were observed by 19F NMR in the culture; 5 of them were identified. The detection limit was
