What is a benefit of using integrated pest management (IPM)?

Integrated Pest Management (IPM) offers a multifaceted approach to controlling pests that emphasizes the use of a combination of methods, including biological control, habitat manipulation, and cultural practices, alongside chemical control when necessary. The correct answer highlights a significant benefit: minimizing pesticide resistance and reducing environmental impact.

When used in conjunction with non-chemical methods, IPM can help maintain the effectiveness of available pesticides by reducing the selection pressure on pest populations, which can lead to resistance. By using a variety of control options tailored to the specific situation, IPM practices promote sustainable pest management that protects not only the crops but also the surrounding ecosystems. This holistic approach helps in reducing negative environmental effects, such as runoff and harm to non-target organisms, making IPM a more responsible choice for long-term pest management.

In contrast, completely eliminating pesticides (as suggested by another option) is not always feasible or practical, since some situations require chemical applications as part of an overall strategy. While some individuals might perceive IPM as less costly, it's essential to note that the initial investment in training and understanding these diverse methods could lead to greater benefits at a later stage. Lastly, implementing IPM effectively relies on proper training and understanding of various strategies, which would make it impractical
