Dissipation and Persistence of Imidacloprid used as Seed Treatment in Peas

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).
