Liquid composition with fungicide, bactericidal and bacteriostatic activity

A method of preparing a fungicidal, bactericidal or bacteriostic plant-protection composition comprising at least one inorganic salt, one oxide or one hydroxide of copper in suspension in an aqueous emulsion of at least one monoterpene, comprising micronizing said inorganic salt, oxide or hydroxide of copper and other ingredients of the composition comprising at least one monoterpene, water and at least one surfactant until a stable homogeneous suspension is obtained in which the size of the particles is less than 6 μm.

A method of preparing a fungicidal, bactericidal or bacteriostic plant-protection composition comprising at least one inorganic salt, one oxide or one hydroxide of copper in suspension in an aqueous emulsion of at least one terpenic derivative, comprising admixing said inorganic salt, oxide or hydroxide of copper, having a diameter not greater than 6 μm, with other ingredients of the composition comprising at least one terpenic derivative, water and at least one surfactant until a stable homogeneous suspension is obtained.

A method of enhancing the efficacy of an inorganic salt, oxide or hydroxide of copper in a plant-protection composition, comprising combining said inorganic salt, oxide or hydroxide of copper in suspension in an aqueous emulsion with at least one monoterpene.

A method of treating plants with a product based on an inorganic salt, oxide or hydroxide of copper, comprising spraying an effective quantity of a plant-protection mixture prepared by mixing, in aqueous form, a composition of an inorganic salt, oxide or hydroxide of copper in suspension in an aqueous emulsion containing at least one monoterpene, on the plant to be treated.
