UTILISATION DE COMPLEXES METALLIQUES COMPRENANT UN LIGAND DERIVE DE L'ACIDE 2-ARYL-2-HYDROXYACETIQUE ET UN CATION DE METAL DIVALENT OU TRIVALENT POUR LE TRAITEMENT DES DEFICIENCE EN METAUX DES PLANTES
The invention relates to the use of metal complexes comprising a ligand derived from 2-aryl-2-hydroxyacetic acid and a divalent or trivalent metal cation and to the use of the said ligands in dissolving divalent or trivalent metal cations in aqueous phase. The said complexes can be used to treat metal deficiencies in plants.
