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.

Application

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).

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

The formation of inclusion complexes with beta-cyclodextrin was studied for several popular fungicides of different types: prochloraz, 2-phenylphenol, thiophanate methyl, 8-hydroxyquinoline, and benalaxyl. Phase solubility diagrams showed that in all cases complexation takes place, leading to an important increase of
