Se llevó adelante el taller teórico/práctico habilitante para la asistencia de difusores para el control de la plaga.

Colocación de difusores.
Colocación de difusores.

Más de 100 productores del departamento sureño se hicieron presentes el día de ayer, en la Unión Vecinal de Calle Larga, ubicada en Ruta 143 y Calle 5, para recibir los difusores a fin de implementar la Técnica de Confusión Sexual. La asistencia comprende la cobertura de 700 has de cultivo en el Departamento.

En el encuentro se abordaron aspectos técnicos, tales como biología, información sobre el estado de situación, manejo integrado de la plaga y utilización de la Técnica de Confusión Sexual, entre otros; así también el encuentro se complementó con tareas a campo, permitiendo que los productores instalen los difusores en las fincas y de esta forma incorporen los principios elementales a través de la experiencia directa.

Esta capacitación se suma a la realizada en los distritos El Zampal y La Arboleda, sobre la metodología de control de a la palga mediante la aplicación de la Técnica de Confusión Sexual, y a General Alvear en la finca ubicada en Diagonal Pellegrini 2588.

La Técnica de Confusión Sexual (TCS)

Es una herramienta de vital importancia dentro del Manejo Integrado de plagas. En los últimos años la superficie bajo TCS ha ido en aumento a nivel global.

Normalmente en el cultivo de la vid la hembra de Lobesia botrana libera una feromona sexual para atraer al macho. Los machos detectan el rastro para localizar y copular a las hembras.

La Confusión Sexual es la perturbación de la atracción sexual de los machos hacia las hembras, provocada por la impregnación del aire de una feromona. La feromona sintética que atrae y confunde a los machos se encuentra en el interior de difusores, dispensers o emisores de feromonas.

Una vez instalados los difusores en el viñedo comienzan a liberar feromona, generando una nube que provoca confusión en los machos quienes no pueden percibir las feromonas que liberan las hembras y no las encuentran para poder copularlas.

  1. Hello there, I do believe your site could possibly be having web
    browser compatibility issues. When I take a
    look at your blog in Safari, it looks fine however, if opening in I.E., it has some overlapping issues.

    I just wanted to provide you with a quick heads up!
    Other than that, wonderful blog!
