When is a long-lasting pesticide residue desirable?

1. During the application process

2. For long-term pest control

3. When immediate results are required

4. For cosmetic purposes

The correct answer is: For long-term pest control

A long-lasting pesticide residue is desirable for long-term pest control because it helps manage persistent pest populations over an extended period without the need for frequent reapplication. This is particularly beneficial in situations where pests pose ongoing threats to crops, structures, or health. The extended efficacy of the pesticide allows for a reduction in labor and costs associated with repeated applications while also ensuring a sustained level of pest management. In contrast, the application process itself may not require lasting residues, as the objective is often to minimize exposure during and immediately after application. Immediate results might be prioritized in situations requiring quick pest elimination, which does not necessarily involve the benefits of a long-lasting residue. Lastly, using pesticides solely for cosmetic purposes does not align with pest management goals and focuses more on aesthetics than effective control, which does not typically require extended residual activity.
