YFRAN-ELVIRA, María de las M. et al. Analysis of pesticides and quality of citrus fruits in the internal market of Corrientes- Argentina. cultrop [online]. 2019, vol.40, n.3  Epub 17-Jun-2019. ISSN 1819-4087.

Corrientes, among the main citrus producing provinces, contributes 23 % to the national production. The use of very diverse chemical products in the agricultural production to control plagues and diseases, to diminish risks and losses of the agricultural systems, has been a permanent challenge. The use of such products is due to the biocidal properties and their selectivity. The objective was to evaluate the presence of pesticide residues in the juice and parameters of fruit quality by physicochemical characteristics. Three samples were taken in two consecutive years collecting samples by five replicates, evaluating the presence of residues of pyrethroid pesticides (cypermethrin, deltamethrin, alphacypermethrin, lambdacyhalthrine) carbamates (aldicarb, carbofuran) and organochlorines (endosulfan) and the variables: bark thickness, diameter equatorial, fresh mass, content and percentage of juice, total soluble solids, total acidity and maturity index. The fruits did not present detectable toxic residues. The quality parameters of Valencia orange fruit, mandarins Nova, Murcott and lemon Eureka presented adequate fruit size, high amount of juice and °Brix that exceed the standard levels. The highest juice values and maturity index were found in orange and tangerines, which were of interest for both, fresh consumption and industry.
