BOVI MITRE, M.G.; WIERNA, N.R.; RETAMOZO, Z.  y  RUGGERI, M.A.. Imazalil Pesticide Degradation Curve in Mature Grapefruit During LongTerm Storage. Inf. tecnol. [online]. 2004, vol.15, n.3, pp. 67-70. ISSN 0718-0764.

An experimental degradation curve for the plaguicide Imazalil was constructed for grapefruit from Salta Province(Argentina) where the fruit was stored under refigeration at 9°C for 35 days. This study allowed determination of the different concentrations of plaguicide contained by the fruit during transport, refrigeration, and exporting to various international destinations. From a sample of 100 Imazalil-treated fruits stored at 9°C, periodic analyses were made in triplicate of the grapefruit skins using the method of Tafuri. The results showed that after 34 days the concentration of Imazalil did not exceed the maximum regulation limit (LMR= 5 ppm). It is concluded that this post-harvest treatment allowed the maintenance of good phytosanitary conditions which allowed this product to reach international destinations with low concentrations of residues
