Which of the following mistakes in turf management can lead to increased pest problems?

Not aerating turf can significantly contribute to increased pest problems. Aeration is a crucial practice in maintaining healthy turfgrass because it alleviates soil compaction, allowing air, water, and nutrients to penetrate more effectively to the root zone. When soil becomes compacted, it limits root growth and can lead to reduced turf health, making it more susceptible to various stressors, including pests and diseases.

In compacted soil, the turfgrass roots may struggle to access essential resources, weakening the plants and creating an environment that is conducive to pest infestations. Additionally, poor drainage often associated with compacted soil can increase the likelihood of fungal diseases, which can further attract pests. Therefore, neglecting aeration can lead to a cascade of issues, ultimately resulting in a turf environment that is vulnerable to pest problems.

In contrast, proper fertilization, regular irrigation, and frequent mowing are practices generally associated with promoting healthy turf, thus reducing the likelihood of pest infestations. These practices contribute positively to the overall health and resilience of the lawn.
