General description

Lactofen is a broad-spectrum post-emergent herbicide. It acts by inhibiting protoporphyrinogen oxidase by causing lipid peroxidation of the cell membrane.

Application

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Lactofen may be used as an analytical reference standard for the determination of the analyte in:
  • Environmental samples by high performance liquid chromatography (HPLC) coupled to tandem mass spectrometric detector (MS/MS), ultraviolet (UV) detector and circular dichroism (CD) detector.
  • Fruit and wheat flour matrices by on-line turbulent flow chromatography (TFC) combined with LC-MS/MS.
  • Agricultural products using gas chromatography coupled to flame photometric detector (GC-FPD).

Lactofen, the active ingredient of the soybean disease resistance-inducing herbicide, Cobra, induces large accumulations of isoflavone conjugates and aglycones in soybean tissues. The predominant isoflavones induced in cotyledon tissues are daidzein (and its conjugates) and formononetin and glycitein aglycones. The...
