Which of the following practices is part of integrated pest management in turfgrass?

The selected practice incorporates a multifaceted approach that is fundamental to integrated pest management (IPM). Spot treating with a selective herbicide targets specific weed populations while minimizing the impact on non-target plants and beneficial organisms. This strategy is complemented by cultural controls, such as proper mowing, watering, and fertilization, which enhance the turfgrass's overall health and resilience against pests or weeds.

Cultural controls play a critical role in IPM by addressing the environmental factors that contribute to pest problems. For example, maintaining proper mowing height can promote stronger grass that can naturally outcompete weeds. This method reduces the reliance on chemical treatments, which aligns with the IPM philosophy of using the least harmful techniques first.

Utilizing selective herbicides in specific areas, as opposed to blanket applications, minimizes environmental impact and encourages sustainable pest management practices. This approach exemplifies the integration of multiple strategies to manage pests effectively and responsibly, making it a core component of IPM in turfgrass management.
