Question

why is the pesticide treadmill problematic? farmers must increase the amount of pesticide the next time they spray for pests. farmers must decrease the amount of pesticide next time they spray for pests. farmers can never change pesticides once the treadmill is activated. farmers must always use the same pesticides as every other farmer on the treadmill.

Explanation:

The pesticide treadmill refers to a situation where pests develop resistance to pesticides over time. As a result, farmers need to increase the amount or potency of pesticides in subsequent applications to achieve the same pest - control effect.

• Option 1: This aligns with the concept of the pesticide treadmill, as pests' resistance means farmers have to use more pesticide next time.
• Option 2: The opposite is true; farmers usually need to increase, not decrease, pesticide use.
• Option 3: Farmers can change pesticides (e.g., switch to a different chemical or use integrated pest management), so this is incorrect.
• Option 4: Farmers don't have to use the same pesticides as others; they can choose based on their specific needs and pest resistance patterns.

Answer:

A. Farmers must increase the amount of pesticide the next time they spray for pests.
