Agronomy QUESTION #2046
Question 1
Integrated Pest Management (IPM) in crop protection is best described as:
  • Exclusive reliance on biological control agents to eliminate all crop pests
  • A decision-based process using site-specific information to prevent pests from reaching economically damaging levels through coordinated use of multiple compatible tactics including biological, cultural, physical, and chemical methods✔️
  • Scheduled calendar-based pesticide application to prevent any pest damage
  • Total elimination of all pest populations from the farm ecosystem
Correct Answer Explanation
IPM is an ecosystem-based strategy that uses economic thresholds to decide when intervention is needed, then employs the most compatible combination of biological (natural enemies), cultural (crop rotation, resistant varieties), physical, and chemical (as last resort) tactics to manage pests below economically damaging levels with minimum environmental impact.
