Abstract

Green bean (Phaseolus vulgaris L.) is one of the important cash crops; which is subjected to many pests, consequently many pesticides are used. Flutianil as a novel compound and propiconazole as a reference compound, were sprayed at the recommended dose on green bean. Their residues and safety to humans under greenhouse conditions were evaluated. Samples were randomly collected at (2 h), 1, 3, 5, 7, 10, 15 and 21 days, respectively. Extraction was performed applying a quick, easy, cheap, effective, rugged, and safe approach (QuEChERS) to homogenized samples, coupled with HPLC-DAD for residues determination. Method was validated starting with blank samples, spiked at five levels (n = 6). Linearity was assessed by injections in triples (n=3) for five concentrations (0.01 to 10 mg kg -1 each), resulting in good linearity with regression coefficient (R2) 0.9956 and 0.9999, high accuracy, precision, matrix effect, satisfactory recoveries (76.9%–110.2%) and relative standard deviation (<20%). The limits of detection and quantification were 0.01 and 0.05 μg/kg, respectively. Pre-harvest intervals (PHIs) were 10 days and maximum residue limits (EU MRLs) was 0.01 for both pesticides. The assessment of health risk, based on dietary exposure, showed that green beans treated with both pesticides are safe to human.
