Fungicidal compositions are described, comprising: A) a copper salicylate having the following molecular formula (I): C7H4O3Cu.(H2O)n  (I) wherein n represents 0, 1, 2 or 3; B) copper hydroxide Cu(OH)2 (II); C) a copper salt having the following formula (III): 3Cu(OH)2.X(Y)m  (III) wherein: X represents cupric ion Cu2+ or calcium ion Ca2+; Y means chloride ion Cl− or sulphate ion SO42−; m is an integer equal to 1 or 2; optionally in the presence of dispersants, diluents, surfactants and/or co-formulants agronomically acceptable, and the relative agronomical formulations. The use of these fungicidal compositions and agronomical formulations for the control of phytopathogenic fungi in agricultural crops, is also described.
