Abstract:
Fluazifop-butyl, haloxyfop-ethoxyethyl and quizalofop-ethyl, active ingredients of new selective herbicidal preparations, as well as their metabolites converted in to corresponding methyl esters were separated on several gas chromatographic columns. Bromination of fluazifop esters increased significantly the response of the electron-capture detector. Electron impact mass spectra of all the compounds investigated were recorded, and characteristic ions suitable for selected ion monitoring are given.
