Abstract
Uptake of the triazole fungicides, fluquinconazole and tetraconazole from shoot part of onion was assessed by determining residual amounts of applied fungicides in edible and shoot parts of onion after the foliar application. Combined product of fluquinconazole and tetraconazole (14:7, v/v) as a 21% active ingredient of suspended emulsion formulation was diluted at ratio of 500 and 200 times and sprayed on the shoot part of onion after sealing its root part with absorbent paper. At 10 days after the pesticide application, fluquinconazole residue in the shoot part was the greatest as 5.2 mg/kg at 200 times-dilution treatment, while tetraconazole residue in this part was the smallest as 1.2 mg/kg at 500 times-dilution treatment. On the other hand, the pesticide residues in edible parts of onion at all the treatments were less than limits of detection, 0.01 mg/kg. However, fluquinconazole residues in the edible part of onion divided into three groups such as 1st, 2nd, and 3rd layers were detected at concentrations of 0.04 or 0.24 mg/kg, and these results show the different distribution of pesticides in onion depending on divided layers. In addition, chopped onions were soaked in pesticide solutions prepared with dilution of 1,000 times, cooked using three food processing types such as boiling, stir frying, and pickling, and the pesticide residues in them were analyzed. The analyzed results showed the largest pesticide dissipation in onion followed boiling process (76.9~92.6%).
