What is the goal of resistance management?

• A. Eradicate all pests immediately
• B. Increase pesticide dependence
• C. Minimize development of pest resistance to pesticides
• D. Eliminate the need for IPM

Answer: (C)

Resistance management aims to keep pesticides effective for as long as possible by slowing the development of resistance in pest populations. Pests that are repeatedly exposed to the same chemical or mode of action can evolve resistance, so resistant individuals survive and pass that trait on, making the product less effective over time. To prevent this, apply strategies that reduce selection pressure: rotate pesticides with different modes of action, use mixtures or tank mixes only when appropriate, apply at labeled rates and timings, and rely on integrated pest management that includes cultural, biological, and mechanical controls. Regular scouting and adapting tactics when resistance signs appear help maintain control without over-relying on chemicals. The other options—eradicating pests immediately, increasing pesticide dependence, or eliminating IPM—don’t address the long-term goal of preserving pesticide effectiveness and would typically worsen resistance or reduce sustainable pest control.
