Name a pest management strategy that involves crop rotation.

The correct choice reflects the practice of changing the type of crop planted in a given field from year to year, which is known as crop rotation. This strategy helps reduce the buildup of pests and diseases that target specific crops. When you rotate crops, it disrupts the life cycles of pests that may have established themselves in the soil or in the plant community, as they often have a preference for particular host plants.

By altering the crops planted, you make it more difficult for pests to survive, as they may not have a suitable food source in the new crop. Additionally, different crops can have varying nutrient requirements and may improve soil health, further enhancing pest management efforts and promoting crop yield.

The other options do not align with the concept of crop rotation. Using the same crop type every year can lead to increased pest and disease issues as the pests become accustomed to the consistent presence of their preferred hosts. Relying solely on chemical pesticides may provide short-term relief but does not address the underlying issues of pest resistance and environmental impacts. Planting cover crops can be beneficial for soil health but does not inherently involve the concept of rotating primary cash crops as a means of pest management.
