Fungicidal compositions based on copper salts

摘要

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.
