Overview

Sustainable microencapsulation strategy enhances acaricidal efficacy in Panonychus citri management, indicating environmental benefits.

Key Points

  • The aim is to develop a sustainable and efficient controlled-release formulation of cyetpyrafen for pest control.
  • Synthesis of cyetpyrafen-loaded polyurethane microcapsules via interfacial polymerization.
  • Optimized preparation using specific concentrations of TEA and IPDI with a defined oil-to-water ratio.
  • Assessment of pH-responsive release characteristics over a defined period.
  • Microcapsules achieved a loading content of 46.46% with an encapsulation efficiency of 72.24%.
  • Demonstrated sustained release of cyetpyrafen over 144 hours across varying pH environments.
  • Bioassays indicated significant acaricidal activity with median lethal concentration decreasing substantially from 24 to 48 hours.
