Answer :
Final answer:
Chemical pesticides are considered short-term solutions in IPM, used only as a last resort when ecological methods fail. They should be carefully selected and applied in a way that minimizes environmental disruption. The focus of IPM is on reducing reliance on pesticides whenever possible.
Explanation:
Role of Chemical Pesticides in Integrated Pest Management (IPM)
In the context of Integrated Pest Management (IPM), chemical pesticides are generally viewed as short-term corrective measures rather than primary solutions. They should be employed only when more ecologically based control methods (such as cultural or biological methods) are ineffective, hence, they are often referred to as being used as the "last resort". The goal of IPM is to minimize the reliance on chemical methods by prioritizing less harmful techniques and integrating various control measures.
When chemical pesticides must be used, it is important to select them carefully. This means choosing products that are non-persistent and applying them in a targeted manner to reduce their negative impact on the environment and beneficial organisms. For example, using targeted pheromones can greatly reduce the need for broader-spectrum pesticides.
Conclusion
Overall, while chemical pesticides can play a role in managing pest populations, their use in an IPM framework is carefully managed and minimized to reduce environmental impact and enhance sustainability.
