General description
Diflufenican is a pre- and early post-emergence herbicide used to control dicotyledonous weeds in winter cereals, including Galium aparine, Veronica hederifolia, Veronica persica and Viola arvensis, which are resistant to substituted urea herbicides.
Application
Diflufenican may be used as a reference standard in the determination of diflufenican in water samples using solid-phase microextraction followed by gas chromatography coupled with ion trap-tandem mass spectrometry (SPME-GC-ITD-MS/MS).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
