Modern agriculture makes use of chemical pesticides to increase the crop productivity so as to meetthe daily needs of uncontrolled population growth. These increase the productivity neglecting thefertility of soil and food quality, hence risking the health of human beings including animals.Fenpyroximate is a kind of acaricide which attacks and kills mites and decreases the growth of larvae.A method is established for the detection of fenpyroximate and stop excessive use of pesticide. Afterperforming several tests on various wavelengths, the λmax for the detection of fenpyroximate was 435nm for azo dye. Limit of detection (LOD) and limit of quantification (LOQ) was found to be 0.687 μgmL-1 and 2.083 μg mL-1, respectively. Furthermore, molar absorptivity, Sandell′s sensitivity were calculatedto be 2.3 × 10-7 mol-1 cm-1 and 1 × 10-5 μg cm-2, respectively. The azo dye follows Beer′s law in therange 5 μg to 14 μg in 10 mL that can be easily detected by using spectrophotometric analysis. Thismethod is very sensitive, low cost and less time consuming. The present method is applied successfullyin various vegetables (i.e. apple, cucumber, potato, spinach, etc.) soil and water samples.
