Abstract
Residue trials of cypermethrin in starfruit (Averrhoa carambola) were conducted to estimate the maximum residue limit (MRL). Five trials were conducted at two commercial growers plots in Mantin Negeri Sembilan. The study plots contained 120 mature starfruit trees which were selected and treated with cypermethrin using the manufacturers recommended rate (0.023 kg a.i./ha). The insecticide was applied with a motorized sprayer at weekly intervals. Starfruit samples (2kg) were randomly collected from the plots at 0 1 3 4 5 and/or 7days after the last spray. Analytical procedure of cypermethrin extraction was validated prior to actual analysis. Satisfactory recoveries ranging from 92.6 to 106.7 were obtained for the fortified starfruit samples. Results showedlowevels of cypermethrin residues in starfruit ranging from 0.01 to 0.09 mg/kg. The determined value of proposed MRL was 0.2 mg/kg. The Dietary Intake Assessment based on Malaysian Food Consumption Pattern confirmed that the proposed MRL concentration will not cause health risks to consumers.
