Which statement is true about cultural control practices?

The statement regarding cultural control practices that is true is that they modify the environment or host to prevent infestations. Cultural control practices are a key component of integrated pest management (IPM) and involve changing how crops or landscapes are managed to make the environment less favorable for pests. This can include practices such as crop rotation, adjusting planting times, conserving beneficial organisms, and managing irrigation effectively. By modifying these elements, the likelihood of pest infestations can be reduced, thus keeping pest populations in check without relying solely on chemical pesticides.

Other options do not accurately reflect the nature of cultural controls. For instance, cultural practices do not eliminate pests entirely; rather, they aim to mitigate the risk of infestations. Additionally, they do not rely exclusively on chemical inputs as they focus on non-chemical methods. Finally, cultural controls are applicable not only in agricultural settings but can also be used in urban landscapes, gardens, and other areas, demonstrating their versatility beyond just agriculture.
