Which of the following is a step in IPM?

• A. Pest detection and identification.
• B. Seasonal pruning schedule.
• C. Ignoring monitoring results.
• D. Random pesticide rotation without thresholds.

Answer: (A)

Accurate pest detection and identification is essential in IPM because you must know exactly what is attacking the plants before you decide how to manage it. Knowing the pest species informs what life stage is present, how it causes damage, and which control methods are likely to work. This step sets up effective monitoring, helps establish action thresholds, and ensures you choose targeted tactics rather than broad, unnecessary treatments.

Cultural practices like a seasonal pruning plan can support plant health and reduce pest habitat, but they’re not the specific diagnostic step IPM relies on to guide decisions. Ignoring monitoring results would undermine IPM, since decisions are based on observed pest levels and trends. Random pesticide rotation without thresholds ignores the data-driven, decision-making framework that IPM uses to minimize impacts and resistance, making it inconsistent with IPM principles.
