Diflubenzuron Mass Concentration Determination Method in Pesticides Using High-Performance Liquid Chromatography.

AIMS

Pesticides are actively used in agriculture to protect crops from pests, and accurate determination of the concentration of their active ingredient is critical to ensuring their efficacy and safety. The research aims to develop a methodology that will enable the accurate determination of the mass concentration of diflubenzuron, a widely used active ingredient in pesticide formulations. This is achieved through the use of high-performance liquid chromatography (HPLC).

METHODS

The proposed method for determining the mass concentration of diflubenzuron using HPLC was developed through a series of experiments and optimisation steps. The sample preparation procedure was optimised to extract the maximum amount of diflubenzuron from the pesticide formulation.

RESULT

The chromatography conditions were optimised to separate diflubenzuron from other components in the sample matrix. A calibration approach was established for accurate quantification of diflubenzuron in the sample based on peak area measurements. The developed method can be widely used in agriculture, where accurate determination of diflubenzuron concentrations in pesticide formulations is critical for proper application and regulatory compliance. Both regulatory organizations and pesticide manufacturers can use it for batch-release testing and quality control to evaluate the efficacy and safety of pesticide products. In addition, the method can serve as a valuable tool for researchers and analysts working with pesticide residues in crops and environmental monitoring studies.

CONCLUSION

The optimised sample preparation, chromatography conditions, and calibration approach provide reliable and reproducible results.
