摘要：
The present invention relates to a formulation for the control of fungal diseases in the agricultural production of orchards, strawberries and ornamental plants characterized by comprising silver nanoparticles (AgNPs) as an active ingredient with fungicidal activity. The said formulation synthesizes from silver oxide, phosphate silver, silver chloride, silver sulfate and Ag+ positive ions from particles and silver metal electrodes. At least one anionic surfactant selected from the group consisting of sodium lauryl ether sulfate, carboxylate, sulfonate, phosphate, and at least one nonionic surfactant selected from the group consisting of polysorbate 20, Polysorbate 60 and polysorbate 80 or amphoteric surfactants like Cocamidopropyl propylamine oxide. Further, at least one cationic surfactant selected from the group consisting of quaternary ammonium salts, distearyl dimethyl ammonium, and hexadecyltrimethylammonium. Said surfactant is preferably in the form of a dispersion to break the surface tension of the solvent and the resistance to the waxy cuticle of the leaves and the trichomes present in the epidermis of the same, thus facilitating the arrangement of the silver nanoparticles (AgNPs) on the leaf surface. The formulation further comprises at least one protective reactive element selected from elemental sulfur or another sulfur compound such as sulfate, sulfuric acid, sulfonate, sulfite, and sulfur oxide.La invención se refiere a una formulación para el control de enfermedades fúngicas en la producción agrícola de frutales, frutillas y ornamentales que se caracteriza por comprender nanopartículas de plata (NPsAg) como ingrediente activo con actividad fungicida, sintetizadas a partir de óxido de plata, fosfato de plata, cloruro de plata, sulfato de plata y los iones Ag+ derivador partículas y electrodos metálicos de plata al menos un tensoactivo o surfactante aniónico seleccionado del grupo que consta de lauril éter sulfato de sodio, carboxilato, sulfonato, fosfa
