Persistence in pesticides is defined as:

Persistence in pesticides is defined as:

• A. How long the pesticide remains active
• B. Its shelf life
• C. How quickly it degrades
• D. Its color

Answer: (A)

Persistence is about how long the pesticide stays active and continues to provide pest control after it’s applied. It’s a measure of the duration of its effectiveness in the environment, not how long the product can be stored (shelf life) or any physical trait like color. The longer a pesticide remains active, the higher its persistence; this is influenced by factors such as sunlight, temperature, moisture, soil characteristics, and microbial activity, which affect how slowly or quickly it degrades. So the best description is the length of time the pesticide remains chemically active and effective.
