AB - The degradation kinetics and residual levels of abamectin (Abalone 1.8% EC)
were estimated in potatoes under field conditions by employing a validated Quick,
Easy, Cheap, Effective, Rugged and Safe (QuEChERS) Method followed by High Performance
Liquid Chromatography with Diode Array Detector (HPLC-DAD) for quantification.
At fortification levels of 0.05, 0.1, 0.25 and 0.5 mg kg-1, it was
shown recovery was 89%, with Coefficient Variation (CV%) was <9% in potato
tubers. The LOQ for potatoes was found to be 0.03 μg kg-1. After
one single application of abamectin the average residues levelin potatoes was
observed to be 0.65 mg kg-1 after 1 day of application. The terminal
residues of abamectin were below the maximum residue limit (MRL 0.01 mg kg-1)
after 10 days at a single dosage. Half-life of abamectin was observed to be
3.5 days at the recommended dosage which considered to be safe for human beings.
These data could provide guidance for the proper and safe use of this pesticide
on vegetable-field ecosystems.
