The invention concerns the use of alginate oligomers in sequence α(1-4)Guluronane and/or β(1-4)Mannuronane having a DP greater than 30, as an active ingredient of biocontrol products in plants, and that may be combined with another molecules such as phytohormones, against cryptogamic diseases of plants, in particular of vine (Vitis vinifera), or to protect other species against aggressors such as pathogenic microbes or insects.

Colloidal silver particles are incorporated into emulsions and other compositions that find use, for example, as pharmaceutical and dermatological serums, creams, lotions and ointments.

Disclosed is a method for preventing, controlling or treating a fungal infection on a plant. The method includes applying to such plant organ a non-fungicidal amount or a potentiating amount of a composition including a potentiating agent of a plant defense molecule, in association with a phytopharmaceutical vehicle.

A composition, comprising a solvent and a compound selected from antimicrobial compounds or antiviral compounds. The compound is soluble in the solvent and/or emulsifiable in the solvent. The solvent and the compound are present in the composition at concentrations such that the composition are non-toxic to humans, dogs, and cats. The composition is capable of being applied onto a surface.
