Question

what comes after monitoring pests in ipm if pest levels exceed the acceptable limit?
ignore the issue and hope for the best
eradicate all pests with chemical pesticides
plant more crops and hope the pests dont spread
utilize biological, cultural, and mechanical controls

Explanation:

In Integrated Pest Management (IPM), when pest levels exceed acceptable limits after monitoring, the approach is to use a combination of biological (e.g., using natural predators), cultural (e.g., crop rotation), and mechanical (e.g., traps) controls as a first line before considering chemical pesticides. Ignoring or planting more crops are not IPM practices, and eradicating all pests with chemicals is not the first step in IPM (it's a last resort or used sparingly). So the correct option is the one about utilizing biological, cultural, and mechanical controls.

Answer:

utilize biological, cultural, and mechanical controls
