What are the three practices that form the foundation of resistance management?

• A. Use IPM and rotate MOA
• B. Use pesticides only when needed
• C. Rotate pesticides with different MOA
• D. All of the above

Answer: (D)

Resistance management relies on a trio of practices that work together to slow how quickly pests adapt. First, using integrated pest management (IPM) means favoring non-chemical controls and applying pesticides only when monitoring and thresholds indicate it’s truly needed, which reduces overall chemical exposure and selection pressure. Second, applying pesticides only when necessary further limits unnecessary pest exposure to a given chemical. Third, rotating pesticides with different modes of action prevents pests from repeatedly facing the same chemical’s pressure, reducing the chance that they develop resistance to any one mode of action and lowering the risk of cross-resistance. When you combine these approaches, you create a broader, more effective strategy for delaying resistance, so choosing all of the above is the best option.
