Dissipation and residues of emamectin benzoate in cabbage.
Emamectin benzoate residue dynamics and final residues in supervised field trials at GAP conditions were studied. An HPLC-MS analytical method for the determination of emamectin benzoate in cabbage and soil was developed. The recoveries of emamectin benzoate on cabbage and soil were observed from 71% to 102% at fortification levels of 0.01, 0.1 and 1.0 mg/kg. The reported limit of quantification (LOQ) was found to be 0.01 mg/kg. The dissipation experiments showed the half-lives (T(1/2)) of emamectin benzoate was around 1 days. At pre-harvest intervals (PHI) of 7 and 12 days, emamectin benzoate residue was observed to be below the LOQ.
