Which of the following is NOT a technique used in Integrated Pest Management?

Integrated Pest Management (IPM) is an effective approach that combines multiple tactics to manage pests in an environmentally and economically sustainable manner. The focus of IPM is to utilize a variety of strategies, which includes biological control, cultural control, and mechanical control, as well as chemical methods when necessary.

The correct answer highlights that "Only chemical control" is not a recognized technique within the framework of IPM. This is because IPM emphasizes a holistic approach that prioritizes integrated strategies over reliance on any single method, particularly chemical pesticides. By using a combination of controls, IPM seeks to reduce pest populations while minimizing the impact on non-target organisms and the environment.

Biological control involves the use of natural predators or parasites to manage pest populations, while cultural control refers to practices that reduce pest establishment, reproduction, and survival through changes in agricultural practices. Mechanical control includes physical methods such as traps or barriers to manage pest issues. Hence, these methods align with the principles of IPM, whereas the concept of solely relying on chemical control does not, as it contradicts the core philosophy of integrated pest management.
