Title: PERSISTENCE OF ABAMECTIN RESIDUES IN/ON BRINJAL (Solanum melongena)
Abstract: Spray application of abamectin (CHA 2062) was given twice to brinjal crop at 15 days interval at the recommended dose and double the recommended dose of 14.4 and 28.8 g a.i./ha during December, 2007-March, 2008 to study its residue persistence. Initial residues of abamectin on brinjal from the two treatments were 0.202 and 0.815 mg/kg, respectively. The residues persisted for 3 days from both the treatments and reached below the quantifiable limit of 0.01 mg/kg on the 5th day. Residues of abamectin on brinjal dissipated with the half-life of less than 1 day and the pre-harvest interval (PHI) or the time taken for the residues on brinjal to reach the permissible level of 0.02 mg/kg was 3 days. Field soil analyzed 10 days after the last treatment was free from abamectin residues.
