As part of an integrated pest management program, what action should an applicator take?

The correct answer is to evaluate the results of a pesticide application, as this is a crucial step in an integrated pest management (IPM) program. Evaluating the effects of pesticide applications allows the applicator to assess the effectiveness of the treatment and determine if the goals of pest control have been achieved. This evaluation helps in making informed decisions about future pest management strategies, whether that involves adjusting pesticide usage, implementing alternative control methods, or modifying the application techniques.

Monitoring and evaluating results is a key principle in IPM, as it encourages the use of a comprehensive approach that includes various methods of pest control rather than relying solely on chemical interventions. This holistic strategy ensures that pest populations are kept in check while minimizing potential negative impacts on the environment and non-target organisms.

Choosing to increase pesticide usage does not align with the principles of IPM, as it could contribute to resistance development in pest populations and additional environmental concerns. Ignoring previous applications disregards the knowledge gained from past experiences, which is crucial for future pest management decisions. Reducing pest populations with chemicals only limits the applicator to a single method of control, which is counterproductive to the IPM philosophy that emphasizes a combination of cultural, biological, and chemical methods for effective and sustainable pest management.
