<p>The invention relates to a process for obtaining synergistic mixtures consisting of plant grwoth stimulators and pesticides. According to the invention, the process consists in reacting phosphonic acid, as P2O5 source, with KOH or K2CO3 solutions, as a source of K2 O, and with ammonia solutions, as N source, the reaction being completed by the addition of urea, so that the macroelements content expressed as a sum of N, P2O5 and K2O ranges from 80 to 250 g/kg, followed by adding EDTA as such or as sodium, potassium or ammonium salt, up to the dissolution, followed by introducing borate of soda or boric acid and water-soluble Mg, Ca, Cu, Zn, Fe, Mo, Cr, V, Mn salts as a sourse of microelements, in a total amount, expressed as a metal sum, of 0.8 to 6 g/kg in a molar ratio of EDTA/atom gram of metal ranging from 1.25 to 1.70, followed by emulsifying the resulting aqueous solution with an addition of naphthenic acids and alkaline salt of laurylsulphonic acid, the thus obtained growth stimulator being finally diluted with water, in a ratio of 1/250 ... 1/500, in the presence of pesticide conditioned in an emulsifiable form.</p> |
