Which pest control strategy may include rotating crops and tilling the soil?

Cultural controls refer to practices that modify the growth environment to make it less conducive to pest problems. This can include rotating crops to disrupt pest life cycles, as different crops may have varying susceptibilities to specific pests. When crops are rotated, it can prevent pests from establishing a stronghold in the soil, as they may not find their preferred food source in the new crop.

Tilling the soil is another example of a cultural control method, as it can help manage pests that are overwintering in the soil or can disrupt their life cycles by exposing them to adverse conditions. Both crop rotation and tilling are proactive management strategies that rely on altering agricultural practices to minimize pest populations, showcasing an important aspect of integrated pest management.

The other options describe different strategies. Mechanical controls involve physical methods of pest removal, legal controls pertain to regulations and policies governing pesticide use and pest management practices, and natural controls rely on biological agents or natural predators to keep pest populations in check. While these strategies are effective in their own right, they do not specifically involve the direct modification of cultivation practices like crop rotation and tilling do.
