Dissipation and Persistence of Imidacloprid Used as Seed Treatment in Peas
Keywords:Imidacloprid, seed treatment, peas, residues, persistence, leaves, seed, mature pod, fodder, QuEChERS method
Dissipation and persistence study of imidacloprid on peas as seed treatment revealed presence of 6.47 and 9.92 mg kg-1 residues on green pea leaves at a dose of 1.8 g and 3.6 g a.i. per kg of seed, respectively after 19 days of treatment. Residues of imidacloprid dissipated below limit of quantification of 0.01 mg kg-1 after 49 and 54 days of treatment. Residues of imidacloprid were found below limit of quantification of 0.01 mg kg-1 in immature pod with succulent seeds, succulent seeds (shelled), mature pod with seeds, mature seeds (shelled), soil and dry fodder (without root and pod).
