Implication

Randomized trial evaluates insecticidal efficacy and safety of microcapsules in agricultural applications, highlighting environmental benefits.

Key Points

  • This research aims to enhance the stability and effectiveness of lambda-cyhalothrin using composite microcapsules while reducing toxicity risks.
  • Developed microcapsules via interfacial polymerization and sol-gel technology with IPDI and TEOS.
  • Characterized microcapsules for particle size, encapsulation efficiency, and release rates.
  • Assessed insecticidal efficacy on Hyblaea puera and evaluated aquatic toxicity against juvenile crucian carp.
  • Achieved 100% mortality of Hyblaea puera larvae at all concentrations within 36 hours of treatment.
  • Demonstrated a significant reduction in aquatic toxicity with a 96-hour median lethal concentration 2.17-fold higher than conventional emulsions.
  • Showed a cumulative release of 78.3% over 7 days without burst release, indicating sustained delivery.
