Area of Science:

  • Agricultural Chemistry
  • Analytical Chemistry
  • Immunology

Background:

  • Cyprodinil is a widely used anilinopyrimidine fungicide for controlling plant diseases in crops.
  • Accurate detection of cyprodinil residues is crucial for food safety and agricultural practices.

Purpose of the Study:

  • To develop and characterize the first immunoassays for cyprodinil detection.
  • To establish sensitive and rapid analytical methods for cyprodinil residue monitoring in food.

Main Methods:

  • Synthesis of novel haptens and conjugation to carrier proteins.
  • Production of polyclonal antibodies.
  • Development and optimization of competitive enzyme-linked immunosorbent assays (CELISAs).

Main Results:

  • Optimized CELISAs achieved IC(50) values of 1.6 ng/mL (direct) and 2.8 ng/mL (indirect).
  • Quantitative recoveries were obtained from spiked apple and grape juice samples.
  • A limit of quantification of 20 ng/mL was achieved for fruit matrices.

Conclusions:

  • The developed immunoassays provide sensitive, straightforward, and rapid tools for cyprodinil residue analysis.
  • These immunoreagents are valuable for monitoring cyprodinil in foodstuffs.
  • The methods support regulatory compliance and food safety assurance.
