The invention relates to an inoculant for the manufacture of cast iron with lamellar, compacted or spheroidal graphite wherein said inoculant comprises between 40 and 80 % by weight of silicon, between 0.5 and 10 % by weight of calcium and/or strontium and/or barium, less than 4 % by weight of aluminium, 0-10 % by weight of manganese and/or titanium and/or zirconium, between 0.5 and 10 % by weight of oxygen in the form of one or more metal oxides, the balance being iron. The invention further relates to a method for producing an inoculant for the manufacture of cast iron with lamellar, compacted or spheroidal graphite, providing a base alloy comprising 40 to 80 % by weight of silicon, 0.5 to 10 % by weight of calcium and/or strontium and/or barium, less than 4 % by weight of aluminium, 0-10 % by weight of manganese and/or titanium and/or zirconium, the balance being iron, and adding 0.5 to 10 % by weight of oxygen in the form of one or more metal oxides to the base alloy.
