摘要：
Method of preparing a suspoemulsion, which contains at least one sulfonylurea suspended in oil and at least one active ingredient soluble in said oil, consisting of the steps of: a. prepare a premix 1 consisting of at least one active ingredient that dissolves in at least one oil b. Prepare a premix 2 consisting of at least two non-ionic surfactants, respectively, an ethoxylated and / or propoxylated fatty alcohol and an ethoxylated and / or propoxylated castor oil, which are dispersed or solubilized in an oil c. Prepare a premix 3 consisting of at least one secondary active ingredient, this being a sulfonylurea herbicide that is dispersed in an oil with the aid of an ethoxylated and / or propoxylated non-ionic block-type oil-soluble dispersant and / or a ethoxylated and / or propoxylated condensed fatty acid d. preparing a premix 4 consisting of at least one suspending agent dispersed in an oil and at least one alkylbenzenesulfonate salt ionic surfactant e. according to the desired final concentration of the active ingredients, an aliquot of each premix is taken. F. The premix mixture is subjected to a grinding process to reduce the particle size of the crystals (on average) from 1 to 15 μm. g. The product finally cools to room temperature naturally and is ready for packaging.Procedimiento de preparación de una suspoemulsión, que contiene al menos una sulfonilurea suspendida en aceite y al menos un ingrediente activo soluble en dicho aceite, que consiste en las etapas de: a. preparar una premezcla 1 que consiste en al menos en un ingrediente activo que se disuelve en al menos un aceite b. preparar una premezcla 2 que consiste en al menos dos tensioactivos no iónicos, respectivamente, un alcohol graso etoxilado y/o propoxilado y un aceite de ricino etoxilado y/o propoxilado, que se dispersan o solubilizan en un aceite c. preparar una premezcla 3 que consiste en al menos un ingrediente activo secundario siendo este un herbicida de sulfonilurea que se dispersa en un a
