Final answer:
One significant benefit of using IPM is reduced reliance on chemical pesticides. Option 1 is correct.
Explanation:
Out of the provided options, the most significant benefit of integrated pest management (IPM) compared to traditional practices is: 1) Reduced reliance on chemical pesticides.
Here's why:
Traditional pest management heavily relies on chemical pesticides, which can have numerous drawbacks:
- Environmental harm: Pesticide use can pollute water and soil, harm beneficial insects and non-target organisms, and disrupt ecosystems.
- Human health risks: Exposure to pesticides can be harmful to human health, causing respiratory problems, skin irritation, and even neurological damage.
- Pesticide resistance: Overuse of pesticides can lead to pests developing resistance, making them even harder to control.
IPM, on the other hand, prioritizes non-chemical control methods wherever possible. This includes:
- Monitoring and identification: Understanding the types and levels of pests present before taking action.
- Habitat modification: Eliminating or reducing pest breeding grounds and attractants.
- Natural predators and parasites: Encouraging populations of beneficial insects and organisms that naturally prey on pests.
- Cultural practices: Using techniques like crop rotation and intercropping to disrupt pest cycles.
While some limited use of pesticides may still be necessary in IPM, the overall reduced reliance on them contributes significantly to:
- Environmental protection: Reduced pollution and harm to ecosystems.
- Human health safety: Lower risk of exposure to harmful chemicals.
- Sustainable pest control: Reduced risk of pesticide resistance and long-term effectiveness.
While the other options (increased crop yields, lower cost, improved soil health) can also be benefits of IPM, they are not always guaranteed and depend on specific scenarios and implementation methods. The reduced reliance on chemical pesticides is a core principle and a consistent benefit of IPM compared to traditional pest control practices.
