There is usually a single best management strategy for most pest problems.

There is usually a single best management strategy for most pest problems.

• A. TRUE
• B. Sometimes true
• C. Not enough information
• D. FALSE

Answer: (D)

The idea being tested is that pest management decisions are context-dependent and usually require more than one approach. In real-world scenarios, there isn’t a universal single best tactic because what works best depends on many factors: the crop and its growth stage, the pest species and its life cycle, field history and pest pressure, weather and environmental conditions, potential effects on beneficial insects, resistance management, and cost considerations. Integrated pest management emphasizes monitoring and using action thresholds to decide when to intervene, and then selecting a mix of tactics—cultural, mechanical, biological, and chemical—possibly rotating modes of action to guard against resistance. Because these variables change from place to place and year to year, the optimal plan often involves more than one tactic or a different tactic at different times. That’s why the statement isn’t accurate overall.
