What should be expected when turf is infested with Masked chafers?

1. The turf lifts easily

2. The turf becomes soggy

3. The turf develops a foul odor

4. The turf thrives better

The correct answer is: The turf lifts easily

When turf is infested with masked chafers, the correct expectation is that the turf lifts easily. Masked chafers are larvae that feed on the roots of grass and other turf plants. This feeding action damages the root system, resulting in a weakened anchor for the grass. As a consequence, the affected areas of turf lose their stability and can be lifted easily, often resembling a sod patch that pulls away from the ground with minimal effort. This phenomenon occurs because the lack of healthy roots means that the turf does not adhere properly to the soil. In well-established turf, the roots help anchor the grass, allowing it to withstand normal wear and tear, as well as environmental stresses. In contrast, when masked chafers are present, the damage they cause leads to a compromised root structure, resulting in lifted patches of turf. While turf infusions may lead to negative effects such as wilting or discoloration, the specific indicator of easy lifting is directly related to the root damage inflicted by these pests. Other options like sogginess, foul odors, or thriving conditions do not appropriately reflect the impacts of a masked chafer infestation. Soggy turf could be a result of overwatering or poor drainage, and foul odors are not typically associated
