Which statement best reflects the principle 'Pesticide as last choice'?

• A. Pesticide should be used as a last resort after non-chemical options are considered.
• B. Pesticide should be applied as the first action in every plan.
• C. Pesticides should never be used.
• D. Pesticides should be applied monthly regardless of pest level.

Answer: (A)

In pest management, pesticides are kept as the last tool after non-chemical options have been tried or are unlikely to be effective. This means prioritizing cultural practices, sanitation, monitoring, resistant plant varieties, and biological or mechanical controls first, and only using a chemical option when pest pressure warrants it based on thresholds. This approach protects beneficial organisms, reduces the risk of resistance, and minimizes environmental impact. Using pesticides as the first action ignores the value of non-chemical methods and can lead to unnecessary chemical exposure and resistance development. Saying pesticides should never be used is too absolute, since a justified chemical treatment can be part of an overall plan. Applying pesticides monthly regardless of pest level wastes resources, undermines monitoring-based decisions, and increases harm to non-target organisms.
