  It is described an aqueous composition for the protection and strengthening of plants comprising: polyethylene glycol in a concentration of 2.0 to 10.0 grams per liter of the composition, wherein the polyethylene glycol has a molecular weight of 6000 to 8000 grams/mol; vitamin A or a derivative or precursor thereof, including mixtures of same, in a concentration of 0.1 to 10.0 grams per liter of composition, and, at least a red coloring agent in a concentration of 0.1 to 10.0 grams per liter of composition, wherein said colorant enables the passage of light at wavelengths greater than 600 nanometers. The aqueous composition is very useful to prevent biotic or abiotic factors generating stress in plants, as well as for quickly improving plants that are in this state. In an embodiment of the invention, the aqueous composition comprises at least one glucoside; and/or at least a foliar fertilizer. In addition, it is described the application method for the composition.
