| 摘要 |
The invention concerns the use, in an aqueous spray mixture comprising a phytosanitary formulation, of an anti-leaching agent comprising: at least a polyhydroxyl and/or polycarboxyl polymer or copolymer; at least a crosslinking agent comprising a metal selected among columns IVA, IB and IIIB of the periodic table; said anti-leaching agent being, in the aqueous spray mixture, in the form of an aqueous solution or dispersion having a polymer or copolymer concentration such that the viscosity of the anti-leaching agent is not more than 10 times the viscosity of the aqueous solution in polymer or copolymer without crosslinking agent, having the same concentration. |
