General description

Benalaxyl is a phenylamide fungicide used for the control of Oomycetes, particularly fungi of the family Peronosporaceae, Phythophthora plasmopara, and Pythium spp. Benalaxyl acts by inhibiting RNA polymerization (polymerase complex I).
Benalaxyl is a systemic fungicide belonging to the acylalanine family. It is found to be active against Oomycetes belonging to Peronosporaceae family.


Benalaxyl may be used as a reference standard for the determination of the analyte in water and wine samples using enzyme linked immunosorbent assay (ELISA).
Benalaxyl may be used as a fungicide reference standard for the determination of the analyte:
  • In rabbit plasma by a chiral high-performance liquid chromatography method with a diode array detector (HPLC-DAD).
  • In vegetable samples by gas chromatography-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.

Benalaxyl (BX), methyl-N-phenylacetyl-N-2,6-xylyl alaninate, is a potent acylanilide fungicide and consist of a pair of enantiomers. The stereoselective metabolism of BX was investigated in rat and rabbit microsomes in vitro. The degradation kinetics and the enantiomer fraction (EF) were determined...
