Protocol requires the extraction of pesticides using acetonitril extraction and purification using the solid phase extract (D-SPE) with C18 as sorbent material (octadecil), followed by gas chromatographic determination coupled with mass spectrometry (GC-MS). The identified compounds was: amidosulfuron , detected in 9 samples of the 13 detected pesticide residue, residue concentrations ranging from 0.01-0.04 mg/kg, propioconazol, detected in a sample of 13 containing 0.03 mg / kg tebuconazole detected in 4 samples of 13 residue concentration ranging from 0.11-0.19 mg/kg. Did not detect deltamethrin and thiacloprid. Regarding the variation on pesticide content, applying the test ANOVA found significant correlations between pesticide residues detected in the three years of study
