Which of the following is a consequence of not adhering to economic thresholds?

• A. Improved crop yield
• B. Increased cost of pest control
• C. Higher market prices for crops
• D. Decreased soil nutrients

Answer: (B)

Not adhering to economic thresholds can lead to increased pest populations and an escalation in pest control efforts, resulting in higher costs associated with managing these pests. Economic thresholds are the pest population levels at which the cost of control measures equals the potential economic loss caused by the pest. If operators do not monitor pest levels and fail to take action when populations exceed these thresholds, they may find themselves facing infestations that require more intensive and, therefore, more expensive control measures.

This situation contrasts with the other outcomes provided. For instance, improved crop yield is generally achieved through effective pest management, which is undermined when economic thresholds are ignored. Similarly, higher market prices for crops usually stem from higher demand or lower supply, not directly from pest control mismanagement. Decreased soil nutrients typically arise from factors unrelated to pest management, such as over-fertilization or poor crop rotation practices. Thus, the most direct and accurate consequence of neglecting economic thresholds is indeed the increased cost of pest control.
