Residue study of imidacloprid in grapes

The initial residue deposit of imidacloprid on grape berries following treatment of Confidor 200 SL at the recommended and double the recommended dose of 80 and 160 g a.i. ha−1 were 0.74 and 1.26 mg kg−1, respectively. Residues remained in the fruits up to 60 days but at a low level of 0.056 and 0.108 mg kg−1.
