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.

INTRODUCCIÓN: La producción de combustibles de segunda generación ha tomado relevancia a nivel mundial, teniendo en cuenta
la necesidad de reducir las emisiones de carbono a la atmósfera y también de encontrar alternativas a los recursos
fósiles de naturaleza finita. En este sentido, Uruguay ya ha empezado a trabajar en el desarrollo de tecnologías para
la producción de biocombustibles de segunda generación. Sin embargo, los costos para producir estos combustibles
son todavía muy elevados, por lo que existe la necesidad de desarrollar tecnologías menos costosas, capaces de
generar mejores beneficios en una escala industrial. Una manera de contribuir a la viabilidad económica de los combustibles
de segunda generación es a través del desarrollo de biorrefinerías. Esta estrategia maximiza la producción
de compuestos de alto valor agregado para cofinanciar la producción de otros, como el bioetanol. |
