What is the effect of mowing height on turf health with respect to pest control?

The choice highlighting that mowing height influences insect activity is correct. The mowing height of turfgrass plays a significant role in how the grass responds to various environmental stressors, including pest pressures.

When grass is mowed at a higher height, it generally leads to a denser canopy, which can create an environment that is less favorable for certain pests. This denser growth can reduce the amount of sunlight reaching the soil surface, thereby limiting the growth of weeds and reducing the habitat available for pests. Additionally, a taller grass can also potentially enhance the plant’s ability to compete with pests by improving its overall health and vigor, making it more resilient to damage.

By managing the mowing height appropriately, turf managers can create conditions that deter pests and contribute to a healthier turf. Adjustments in mowing height can make a significant difference in pest activity, and thus in pest management strategies.

The other considerations, such as nutrient absorption, watering needs, and turf resilience, while relevant to overall turf health, are not as directly linked to pest control as the influence of mowing height on insect activity.
