Which of the following is an example of a cultural control method?

Planting pest-resistant crop varieties is an example of a cultural control method because it involves modifying agricultural practices to make the environment less favorable for pests. By choosing plant varieties that have inherent resistance to specific pests or diseases, the need for chemical interventions can be reduced. This method relies on the natural resilience of plants to deter pests, thereby fostering a healthier agricultural ecosystem.

Cultural control methods aim to alter the conditions in which pests thrive, effectively preventing infestations before they can occur. They can include practices such as crop rotation, intercropping, and the use of planting schedules that make it harder for pests to establish themselves. This proactive approach contrasts with reactive measures, such as applying pesticides, using traps, or biological controls, which focus on addressing pest problems after they arise.
