Method for treating metal deficiency in plants using metal complexes comprising a ligand derived from 2-aryl-2-hydroxyacetic acid and a divalent or trivalent metal cation

摘要

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.
