peer agreement (net): +2lack period Explanation: 3) Período de carencia: Es el tiempo que debe esperarse, después de la aplicación de un producto para consumirlo sin riesgo para la salud. [1] Carencia: El tiempo legal que debe transcurrir entre la última aplicación del plaguicida y la cosecha. Resumen Se investigó la degradación del funguicida Pirimetanil en Fragaria x ananassa Duch. cultivada en Tucumán, Argentina. Se realizaron dos tratamientos con cuatro repeticiones y se usaron las dosis máximas y mínimas recomendadas en la literatura. Los frutos cosechados se extrajeron con solventes orgánicos y en los extractos obtenidos se cuantificó el Pirimetanil empleando cromatografía líquida-líquida de alta resolución. En el tratamiento que recibió la dosis máxima los residuos encontrados a los 11 días fueron 1.72 mg/kg. Esta situación es diferente cuando se aplica la dosis mínima, debido a que en el tercer día se registran valores inferiores al límite máximo de residuos (1mg/kg.). El período de carencia para la región del ensayo es diferente al establecido por la legislación argentina, lo que evidencia la necesidad de realizar análisis en cada zona agro-ecológica.

Two treatments were done with four repetitions and the maximum and minimum doses recommended in the literature were used. Harvested fruits were removed with organic solvents and Pirimetanil was quantified in the extracts using high resolution liquid-liquid chromatography. In the treatment where the maximum dose was applied, the residues found on the 11th day were 1.72 mg/kg. This situation is different when the minimum dose is applied, since on the third day residue values below the maximum limit were registered (1mg/kg). The lack period for the test region is different from that established by argentinean legislation, making evident the need of performing analyses in each agro-ecological area.
