Agrochemical compositions (AC) contain 0.5-50 (preferably 1-20) wt.% of at least one agrochemically-active material (I), and an effective amount of a polyethylene imine (II) having a molecular mass of 300-3000000 (preferably 800-2000000). Also claimed are: (1) the treatment of rice cultures by carrying out a pre-germination phase, followed by applying one or more agrochemically-active materials to the seeds by means of a composition AC, and prolonging the pre-germination phase before sowing; (2) pregerminated rice seeds coated and/or impregnated with AC; and (3) a mass or collection of pregerminated rice seeds, juxtaposed and coated and/or impregnated with AC. |
