Give an example of a cultural control method for managing pests.

Adjusting irrigation practices is a key cultural control method for managing pests because it helps create an environment that is less conducive to pest development and survival. Proper irrigation management can prevent issues such as over-saturation of soil, which might lead to the development of fungal diseases, or drought stress, which can weaken plants and make them more susceptible to pest infestations. By fostering optimal moisture levels that support healthy plant growth and minimize stress, this practice can reduce the likelihood of pest outbreaks and support overall plant health.

Other options, while related to pest management, do not embody cultural control methods as effectively. For example, using insecticides weekly is a chemical control method rather than a cultural one. Planting only one type of crop can lead to pest infestations due to a lack of biodiversity, which may actually increase pest pressure rather than reduce it. Using traps to catch pests is a method of physical control, which is different from cultural practices that involve modifying the environment or management practices to enhance plant health and deter pests.
