Fungicidal co-formulation

The invention relates a concentrated liquid fungicidal composition comprising a fungicidally acceptable carrier and/or surface active agent and (a) at least one compound of formula I, in which R , R , R and A are as defined in the specification, or one of the salts or addition products thereof, which exists in solubilized form; and (b) one or more additional fungicidal active ingredients, which exist as a suspension of fine particles; (c) a solubilizing agent; and (d) a dispersing agent, which has the capability to adsorb irreversibly on the surfaces of hydrophobic particles suspended in water or polar organic solvents. The invention relates furthermore to concentrated fungicidal compositions comprising a fungicidally acceptable carrier and/or surface active agent and synergistically effective amounts of at least one compound of formula I, and chlorothalonil and/or kresoxim-methyl, as well as methods of using a combination of synergistically effective amounts of at least one compound of formula I, and chlorothalonil and/or kresoxim-methyl in the presence of a solubilizing agent to control various fungi, especially on cereal crops such as wheat.
