Area of Science:

  • Agricultural Science
  • Entomology
  • Sustainable Agriculture

Background:

  • Okra (Abelmoschus esculentus) faces significant pest challenges from insects like leafhoppers, whiteflies, and borers.
  • Conventional chemical pest control methods (CM) negatively impact biodiversity and ecosystem health.
  • There is a need for sustainable pest management strategies in okra cultivation.

Purpose of the Study:

  • To evaluate the effectiveness of integrated pest management (IM) and biointensive pest management (BM) modules against conventional chemical methods (CM) for okra.
  • To assess the impact of different pest management strategies on okra yield and economic returns.
  • To compare the effects of IM, BM, and CM on natural enemy populations in okra ecosystems.

Main Methods:

  • Field study comparing integrated (IM), biointensive (BM), and chemical (CM) pest management modules in okra cultivation.
  • Assessment of insect damage to okra leaves and fruits across different treatment groups.
  • Measurement of okra yield, net returns, and cost-benefit ratios for each management module.
  • Monitoring of natural enemy populations in plots treated with different pest control methods.

    • Main Results:

    • Biointensive management (BM) showed the least effectiveness but still outperformed untreated controls.
    • Both integrated management (IM) and chemical management (CM) significantly reduced sap-sucking insects and borer damage.
    • Chemical management (CM) led to a decrease in natural enemy populations.
    • Integrated management (IM) resulted in the lowest fruit infestation (5.06%), highest yield (8.97 t ha⁻¹), highest net return (INR 44,245), and best cost-benefit ratio (3.31).

    Conclusions:

    • Integrated pest management (IM) is a highly effective and economically beneficial strategy for okra cultivation.
    • Sustainable agricultural practices, like IM, offer a safer and more profitable alternative to chemical-intensive pest control.
    • Implementing IM in okra farming can enhance crop productivity and profitability while preserving ecosystem health.
