What prominent method does chemical control utilize?

Chemical control primarily relies on the application of pesticides or herbicides to manage pest populations. This method is focused on using chemical substances designed to eliminate or reduce unwanted organisms that can harm crops, gardens, and structures. Pesticides are formulated to target specific pests, such as insects, weeds, or diseases, which allows for precise control over these organisms while minimizing the adverse impact on the environment when used correctly.

Other options, while important in pest management, serve different purposes. Crop rotation involves changing the types of crops grown in a specific area to disrupt pest cycles and improve soil health, effectively reducing reliance on chemical controls. Physical barriers, such as nets or row covers, prevent pests from reaching plants without the use of chemicals. Biological predators rely on natural enemies of pests to keep their populations in check. These methods can be integral to an integrated pest management approach but do not represent chemical control directly.
