Which statement is true about the use of selective pesticides?

• A. Identify the pest correctly
• B. Use the highest label rate
• C. Use the best formulation
• D. Repeat until pests are gone

Answer: (A)

Identifying the pest correctly is essential when using selective pesticides because these products are designed to target specific pests, not everyone. When you know exactly which pest you’re dealing with, you can choose a product labeled for that pest, which increases the likelihood of effective control while reducing harm to beneficial insects, pollinators, and the crop. Using the highest label rate isn’t right because it can cause crop injury or non-target damage and it promotes resistance by exposing pests to more chemistry than needed. The idea of a “best formulation” isn’t universally true—formulations matter, but what works best depends on the pest, crop, and application method, not a single superior option for all situations. Repeating applications until pests are gone isn’t good practice either; it can drive resistance and increase environmental impact without addressing underlying problems. So, correctly identifying the pest guides safe, effective, and responsible use of selective pesticides.
