Abstract:
A method of preventing leaching of an active agent applied to a plant with an aqueous atomizing spray comprising a phytosanitary formulation comprising said active agent, said method comprising the steps of:a) spraying on the plant said aqueous atomizing spray comprising said phytosanitary formulation, and an anti-leaching agent comprising: at least one polyhydroxylated or polycarboxylated polymer or copolymer, and at least one reticulating agent comprising at least one metal selected from Columns IVA, IB and IIIB of the periodic table of the elements, said anti-leaching agent being present, in the aqueous atomizing spray, in the form of an aqueous solution or dispersion of the polymer or copolymer, with a polymer or copolymer concentration such that the viscosity of the anti-leaching agent is less than or equal to 10 times the viscosity of an aqueous polymer or copolymer solution free from reticulating agent, with the same concentration, and b) forming a gel by drying of the anti-leaching agent on the plant.
