Why should pesticides be considered a last resort in Integrated Pest Management (IPM)?

In Integrated Pest Management (IPM), pesticides are regarded as a last resort primarily to minimize environmental impact and risks to beneficial organisms. The core principle of IPM is to manage pest populations using a combination of practices that reduce reliance on chemical controls. By placing pesticides at the end of the control strategy, IPM practitioners aim to protect non-target species, such as beneficial insects, pollinators, and other organisms that contribute to ecosystem balance. This approach encourages the use of more sustainable methods such as cultural practices, biological controls, and mechanical controls, which can be more environmentally friendly and less disruptive to the ecosystem.

The goal is to maintain pest populations at acceptable levels while allowing the beneficial organisms to thrive, thus reducing the likelihood of pest resistance developing against pesticides. This minimizes the long-term need for chemical interventions and promotes sustainable agricultural practices.
