Abstract: The invention relates to a composition of water-soluble ingredients (CWSI) which when solubilized in water (W) and either in the presence of a wetting agent and/or in the presence of at least one agriculturally acceptable solvent, forms a synergistic composition useful for the control of pathogens and/or the prevention of diseases associated with the presence of said pathogens in and/or on seeds. Said composition of water-soluble ingredients (CWSI) comprises at least one oxidizer in liquid form or solid form, or a precursor thereof in liquid or solid form, said at least one agriculturally acceptable solvent is soluble in water (W); the water-soluble ingredients (CWSI) is dissolved in the water (W), in a weight ratio (CWSI)/(W) ranging from 1:100 to 1:4, and when present, said at least one agriculturally acceptable solvent represents from 2% by volume to 70% by volume of the total volume of the synergistic composition to be formed.

Abstract: A stabilized oxidizer composition, and method and use for improving disinfection, sanitation and/or disease control, and kit for preparing said composition. A stabilized oxidizer composition and a method for improving the stability and/or efficiency of said oxidizer composition. A powdered composition for the preparation of such stabilized and/or more efficient oxidizer composition. A stabilized and/or more efficient oxidizer composition, and method for improving the stability and pesticidal activity of the oxidant when mixed with other pesticides. Uses and methods involving said stabilized and/or more efficient oxidizer composition, and a kit for the preparation of a stabilized and/or more efficient oxidizer composition, advantageously in order to obtain a more efficient control of pathogens in and on any kind of surfaces in general, preferably on surfaces of the tissues of a growing plant. Preferably, the oxidizer mentioned hereinabove may be peracetic acid, hydrogen peroxide, or a precursor thereof.
