The correct answer is: d) All of the above.
Integrated pest management (IPM) is a pest control strategy that uses a combination of methods to reduce pest populations to levels below those that cause economic damage or cause other problems. IPM techniques can include biological control, cultural control, mechanical control, and chemical control.
IPM is important for reducing reliance on chemical pesticides. Chemical pesticides can be harmful to the environment and to human health. They can also kill beneficial insects, which can disrupt the natural balance of an ecosystem. IPM techniques can help to reduce the need for chemical pesticides by using other methods to control pests.
IPM is also important for promoting ecological balance. By using a variety of methods to control pests, IPM can help to maintain a healthy ecosystem. This is important because pests can play an important role in the food chain. For example, some pests help to control populations of other pests.
IPM is also important for improving crop yields. By reducing pest populations, IPM can help to increase crop yields. This is important because it can help to ensure that there is enough food for everyone.
In conclusion, IPM is important for reducing reliance on chemical pesticides, promoting ecological balance, and improving crop yields.
