-proporcionar una disolución que comprende un disolvente orgánico miscible en agua seleccionado de la lista de un éter glicol, un formal glicerol, dimetil sulfóxido y gamma-butirolactona o una de sus mezclas; y un alcohol alcoxilado, y
-añadir a la disolución un ingrediente activo pesticida miscible con el disolvente seleccionado,
5 caracterizado por que, el alcohol alcoxilado es de la fórmula (II),
CH3-(CH2)x-CH2-O-(CH2-CH(CH3)-O)z-(CH2-CH2-O)y-H (II)
donde x es de 10 a 13, y es de 10 a 60; y z es de 2 a 45; y el número mínimo de peso molecular medio de alcohol alcoxilado, expresado en unidades de masa atómica, es al menos 1.000.
La selección del disolvente está dirigida a la solubilidad del ingrediente activo en el disolvente.
10 La composición obtenida como se describe anteriormente puede servir como un par disolvente/tensioactivo para un amplio intervalo de ingredientes activos pesticidas. Para obtener una disolución pesticida emulsionable, se añade un ingrediente activo pesticida miscible con el par disolvente/tensioactivo seleccionado a la pre-emulsión. La miscibilidad se puede comprobar con una prueba de evaluación estándar de solubilidad, conocida por un experto en la técnica. La disolución pesticida emulsionable así obtenida se puede almacenar antes de su uso para obtener una
15 disolución pesticida emulsionada.
La mezcla se puede llevar a cabo a temperatura ambiente o preferentemente a una temperatura elevada. En una realización preferente del método, el método comprende la etapa de calentar la disolución que comprende el ingrediente activo pesticida a una temperatura entre 20ºC a 60ºC, preferentemente entre 30ºC a 60ºC; más preferentemente alrededor de 40ºC. Calentar la mezcla a una temperatura de aproximadamente 40ºC facilita la
20 disolución del pesticida.
En una realización preferente del método, el método comprende la etapa de añadir la composición emulsionable a agua obteniendo así una composición pesticida emulsionada, y aplicar la composición pesticida emulsionada a un cultivo agrícola para el tratamiento de una plaga tratable con el ingrediente activo seleccionado.
Los ingredientes activos pesticidas se pueden usar en la forma de líquidos o polvos. Después de mezclar con el
25 sistema emulsionante de la invención son formulaciones emulsionables que se pueden verter y se dispersan instantáneamente en agua. Las emulsiones que resultan son estables en el tiempo, típicamente del orden de al menos 4 horas. El producto terminado aún no está emulsionado. Cuando se diluye con agua, la composición emulsionable formará la emulsión. La emulsión es estable durante al menos 4 horas.
La composición pesticida según la emulsión se prepara mezclando el disolvente miscible con la composición
30 pesticida a una concentración en el intervalo de 10 g/l para la concentración más baja (por ejemplo en caso de cipermetrina) hasta 800 g/l para la concentración más alta (por ejemplo en caso de triclopyr butoxietil éster). En una realización preferente una composición de la invención se usa para el tratamiento de cultivos agrícolas.
En un aspecto final, la invención proporciona un método para tratar un cultivo agrícola, que comprende las etapas de:
35 -proporcionar un conjunto de partes que comprende:
(a)
un disolvente orgánico miscible en agua seleccionado de la lista de un éter glicol, un formal glicerol, dimetil sulfóxido, gamma-butirolactona o sus mezclas,
(b)
un alcohol alcoxilado; y
(c)
un ingrediente activo pesticida,
40 -mezclar (a) con (b) y (c) proporcionando así una disolución para producir disoluciones pesticidas emulsionables,
-añadir agua a la disolución emulsionando así el ingrediente activo pesticida y obtener una composición pesticida emulsionada que comprende un ingrediente activo en un intervalo de dosis predetermidado,
-aplicar la composición pesticida emulsionada a un cultivo agrícola que sufre una enfermedad tratable con el 45 ingrediente activo seleccionado y el intervalo de dosis,
caracterizado por que, el alcohol alcoxilado es de la fórmula (II),
CH3-(CH2)x-CH2-O-(CH2-CH(CH3)-O)z-(CH2-CH2-O)y-H (II)
donde x es de 10 a 13, y es de 10 a 60; y z es de 2 a 45; y el número mínimo de peso molecular medio de alcohol alcoxilado, expresado en unidades de masa atómica, es al menos 1.000.

Un método para tratar un cultivo agrícola, puede comprender las etapas de: -proporcionar un conjunto de partes que comprende:
(a) un disolvente orgánico miscible en agua seleccionado de la lista de un éter glicol, un formal glicerol, dimetil sulfóxido, gamma-butirolactona o sus mezclas,
5 (b) un alcohol alcoxilado con una media de 6 a 80 moles de óxido de etileno y de 2 a 60 moles de óxido de propileno por mol de alcohol; y
(c) un ingrediente activo pesticida, -mezclar (a) con (b) y (c) proporcionando así una disolución para producir disoluciones pesticidas emulsionables, 10 -añadir agua a la disolución emulsionando así el ingrediente activo pesticida y obtener una composición pesticida emulsionada que comprende un ingrediente activo en un intervalo de dosis predetermidado, -aplicar la composición pesticida emulsionada a un cultivo agrícola que sufre una enfermedad tratable con el
ingrediente activo seleccionado y el intervalo de dosis. La presente invención se describirá ahora en más detalle, con referencia a ejemplos que no son limitantes.
15 Ejemplos.
Ejemplo 1.
En el experimento resumido en la tabla 1, se prepararon disoluciones pesticidas emulsionables comenzando con un conjunto de partes que comprende DMSO 40% + GBL 60%, Tensiofix DMSO40 y una selección entre un grupo de ingredientes activos. Primero, el disolvente DMSO40/GBL60 se mezcló con un tensioactivo no iónico, en particular
20 con Tensiofix UNI01. La mezcla obtenida se dividió en varias muestras. A las muestras se añadió un ingrediente activo seleccionado. La disolución pesticida emulsionable así obtenida se inspeccionó para la estabilidad de la emulsión. Se observó si se obtenía una mezcla homogénea y si no precipitaban cantidades visibles de pesticida.
