What type of damage is most associated with white grubs in turf?

The correct answer highlights that white grubs primarily damage turfgrass by weakening the root systems. White grubs, which are the larval stage of various beetles, feed on the roots of grass plants, leading to significant deterioration in turf health. When the roots are compromised, the plants can no longer effectively absorb water and nutrients, which can cause the grass to wilt, turn brown, and eventually die, creating large patches of dead or dying turf.

This kind of damage is particularly insidious because it occurs below the soil surface, making it less immediately visible than damage done to the grass blades themselves. As a result, areas affected by white grubs may not show signs until significant root loss has occurred, leading to more extensive turf damage. Understanding this is crucial for turf management, as addressing root damage early can help prevent larger issues down the line.

In contrast, the other types of damage referenced in the choices involve different pests or conditions: chewing on grass blades is associated with other insect pests, chewing off flower stems pertains more to certain insects that feed on flowers, and creating visible holes in the surface can be caused by various pests, including surface-feeding insects or other forms of disturbance in the turf. Thus, recognizing the specific impact of white gr
