ABSTRACT.
The dissipation of field-applied difenoconazole, imidacloprid, pyraclostrobin and spinosad on Clementine mandarins (Citrus clementina Hort. ex Tan.) under controlled conditions throughout the citrus production chain was assessed. At harvest, 42 days after application, the dissipation of these pesticides were 80, 92, and 48% for difenoconazole, imidacloprid, pyraclostrobin, respectively, and spinosad was below the level of detectability. At day 28 after application, spinosad was no longer detected. The model equations that best describe the dissipation curves of these pesticides on Clementine mandarins showed different patterns. Their half-life on Clementine, calculated by the best-fitted experimental data, were 19.2 day (1st-order model) for difenoconazole, 4.1 day (Root Factor (RF) 1st-order model) for imidacloprid, 39.8 day (2nd-order model) for pyraclostrobin and 5.8 day (1st-order model) for spinosad. These results are the first record of pyraclostrobin persistence on mandarins, showing a longer half-life in this matrix than those reported for any other fruit. The treated fruit were harvested and submitted to the usual postharvest treatments: first, a hypochlorite drenching was performed; as a second step, imazalil and wax were applied, and then the mandarins were stored at 4 °C. After 32 days, cold storage caused no significant effects on the residue levels of the four pesticides compared with those determined on freshly harvested mandarins. All residues were below their Codex and European Union (EU) maximum residue limit (MRL) for mandarin since the spray application day. MenosABSTRACT.

El EPD Eficiencia de Conversión (EfC) está basado en la medición del consumo a través de comederos automáticos que registran el alimento consumido diariamente para cada animal por un período de prueba de 70 días. Durante la prueba los animales son pesados y medidos por ultrasonografía, conociéndose la
ganancia diaria y composición corporal medida como músculo y grasa. A partir de los registros de consumo obtenidos para cada animal, se estima el consumo de alimento
residual. El mismo se registra como la diferencia entre el consumo real y el consumo esperado de acuerdo al peso, tasa de crecimiento y composición corporal. |
