Which practice is essential in the cultural control of pests?

Choosing plants adapted to site conditions is essential in the cultural control of pests because it significantly enhances the resilience and health of the plants, making them less susceptible to pest infestations. When plants are well-suited to their environment, they are more likely to thrive and develop natural defenses against pests and diseases. This adaptation can include selecting native or drought-resistant species that require less maintenance and are more robust in the face of local pests.

In contrast, using numerous chemical pesticides can lead to negative environmental impacts, including resistance development in pest populations and harm to non-target organisms. Planting all species in monocultures can create a homogeneous environment that pests can exploit, leading to increased susceptibility. Only watering plants during droughts can stress plants and make them more vulnerable to pests, as stressed plants are often less capable of withstanding attacks. Thus, opting for site-adapted plants supports a more sustainable and effective pest management approach.
