Which of the following is not considered a method used in Integrated Pest Management (IPM)?

Integrated Pest Management (IPM) is an ecological approach to managing pests that utilizes various strategies to minimize the impact of pests while reducing the reliance on chemical control methods. The methods used in IPM typically include cultural, physical, mechanical, and biological controls, as well as the judicious use of pesticides when necessary.

Soil poisoning, or the application of toxic substances to the soil to eliminate pests, is not in alignment with the principles of IPM. This method does not consider the environmental impacts and may lead to harm beyond the targeted pest species, impacting beneficial organisms and the surrounding ecosystem. IPM advocates for more sustainable and environmentally friendly practices that reduce risks to human health and non-target wildlife.

In contrast, window screening, covering bushes with netting, and removing tree stumps are all proactive measures aimed at preventing pest entry or establishing barriers, which are essential components of IPM. These methods focus on creating unfavorable conditions for pests rather than resorting to toxic interventions.
