Abstract
The dissipation and residual levels of new generation insecticide chromafenozide in strawberries under field conditions were studied using HPLC-DAD after QuEChERS extraction. The method was validated using blank samples spiked at three levels and the results showed that recoveries ranged from 99% to 110%. The intra- and inter-day relative standard deviations were less than 7.5% and 9.2%, respectively. Estimated limit of detection and limit of quantification for chromafenozide were 0.003 and 0.01Â mg/kg, respectively. The residues of chromafenozide were found to dissipate following first order kinetics and its half-life ranged from 3.53 to 4.07Â days. The results showed that the use of chromafenozide at recommended dose does not pose any hazards to consumers. These results can be utilised in formulating spray schedules and safety evaluation for chromafenozide insecticide in strawberry.
