Formulaciones arcilla-liposomas de sulfometurón para reducir la lixiviación del herbicida

Abstract

La movilidad de herbicidas en suelos es de gran interés desde hace mucho tiempo, por muchas razones entre las que se incluye (1): (i) su potencial para contaminar aguas subterráneas; (ii) reducción en su eficacia cuando el herbicida lixivia por debajo de la zona raíz de las malas hierbas, que puede potencialmente dañar la cosecha tratada; (iii) su potencial para volver a la superficie del suelo con el consiguiente peligro para posteriores cultivos. Las formulaciones de liberación controlada de herbicidas (FLCs) proveen una liberación lenta del ingrediente activo a una velocidad adecuada, reduciéndose de esta forma la cantidad de producto químico necesario para un control eficiente de las malas hierbas. El presente estudio demuestra que el uso de liposomas es una nueva herramienta para el diseño de formulaciones de liberación controlada de sulfometurón (SFM), un herbicida de la familia de las sulfonilureas. El herbicida se incorpora en vesículas formadas por cationes de aminas cuaternarias, dimetildidodecilamonio (DDAB) y dimetildioctadecilamonio (DDOB), que son posteriormente adsorbidos sobre una montmorillonita estándar (SWy-2). La concentración inicial en las soluciones vesiculares del herbicida era de 0.6 mM y del catión orgánico 6 mM.
