What is one way to prolong the effectiveness of pesticides?

The chosen answer focuses on the importance of targeted pesticide application to maintain effectiveness. When pesticides are applied over limited areas instead of widespread usage, it helps to reduce the likelihood of pests developing resistance. This strategy avoids unnecessary exposure in areas where it may not be needed and conserves the pesticide's effectiveness for critical spots.

Additionally, applying pesticides to specific areas allows for better pest monitoring and management. By concentrating efforts on known pest locations, it becomes easier to evaluate the success of the treatment and make informed decisions for future applications. Targeted approaches can also minimize the environmental impact, preserving beneficial insects and surrounding ecosystems.

The other strategies mentioned could lead to decreased effectiveness or the potential for resistance. For example, using the same pesticide consistently can cause pests to adapt and develop resistance, rendering the treatment ineffective over time. Increasing the dose each time can lead to more severe environmental consequences, including the risk of pesticide runoff and harm to non-target organisms. Ignoring pest monitoring fails to provide critical information on pest population dynamics, potentially leading to over-application or under-treatment.
