Answer :
Final answer:
The second basic rule of an Integrated Pest Management (IPM) system is to use pesticides as a 'last resort' and in a manner that minimizes environmental disruption by being targeted and non-persistent.
Explanation:
The second basic rule of an Integrated Pest Management (IPM) system is that pesticides should be used as a 'last resort'. This means that when ecologically based control measures are no longer effective in managing pest populations, pesticides may be deployed.
However, their use must be carefully considered to minimize environmental disruption. This involves selecting pesticides that are non-persistent in the environment and applying them in a targeted manner to avoid affecting non-target organisms and the ecosystem as a whole.
Additionally, IPM emphasizes the importance of using a combination of control methods that include biological, cultural, and mechanical strategies to manage pests effectively.
In summary, the IPM approach advocates for the judicious use of pesticides to maintain a sustainable and ecologically balanced pest control strategy. By using pesticides as a last resort, IPM helps protect beneficial organisms, conserve biodiversity, and reduce pesticide resistance among pest populations.
Notable IPM strategies include the use of pest-resistant cultivars, interplanting, and implementing techniques such as the sterile insect technique for area-wide pest management. These strategies work together to create an effective and environmentally conscious approach to reducing the dependence on chemical pesticides.
