What is a consequence of pesticide resistance on pest management?

• A. More effective and cheaper
• B. No change
• C. Less effective and more expensive
• D. Immediate eradication

Answer: (C)

Pesticide resistance happens when pests adapt to the chemicals used against them, so the same product loses its ability to control them. As resistance grows, the control you get from the pesticide declines, which often means you need more frequent applications, higher doses, or switching to newer, usually more expensive products. That combination—worse control and higher costs—is the real consequence for pest management. It’s not immediate eradication, and it isn’t a situation with no change or with improved effectiveness and lower cost. Understanding this helps explain why resistance pushes researchers and managers toward rotating modes of action and integrating non-chemical methods to keep control affordable and reliable.
