General description

Lenacil is a pre- and post-emergence herbicide used primarily in suger beet crops to control Capsella bursa-pastoris, Lamium amplexicaule, Veronica persica, Anthemis arvensis, Viola arvensis, Polygonum convolvulus, Brassica napus, Papaver rhoeas and Chenopodium album, which acts by inhibiting photosynthesis.

Application

Lenacil may be used as a reference standard for the determination of the analyte:
  • In water sample by the application of planar chromatography with diode array scanning (TLC-DAD) and high-performance chromatography with diode array detection (HPLC-DAD).
  • In dry matrices such as cereal grain and certain feeding stuffs by gas chromatography/triple quadrupole tandem mass spectrometry (GC–MS/MS).

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

The effect of pyramin (1-phenyl-4-amino-5-chloro-piridazone-6) and venzar (3-cyclohexyl-5,6-trimethyleneuracil) on growth, oxygen uptake and nitrogenase activity was examined. The possibilities of herbicide accumulation in cells and binding by mucopolisaccharides were also tested. Stimulation of growth was observed in the presence of
