Which of the following pest control methods is deemed legal?

The inclusion of all pest control methods as legal is a reflection of their accepted use within integrated pest management practices. Cultural measures involve modifying agricultural practices to reduce pest establishment, reproduction, and survival. This includes crop rotation, planting resistant varieties, and maintaining healthy conditions that optimize plant health.

Biological measures harness natural predators or parasites to control pest populations, effectively using ecological relationships to maintain balance and minimize reliance on synthetic chemicals.

Chemical measures refer to the use of pesticides and other chemical agents to control pests, which are regulated by government agencies to ensure safety for human health and the environment.

Each of these methods can be legal as long as they adhere to local regulations and safety guidelines. Integrated pest management encourages the use of a combination of these approaches to effectively manage pest populations in a sustainable and legally compliant manner.
