What is a key characteristic of chemical control in pest management?

Chemical control in pest management is characterized by the inclusion of substances that are specifically designed to kill, repel, or inhibit the growth of pests. This typically encompasses a broad range of products, such as pesticides that directly target insects or diseases, repellents that deter pest presence, and growth regulators that affect the development of pest populations.

By utilizing these chemical agents, pest management strategies can effectively reduce pest populations and manage infestations in various settings, including agricultural and landscape environments. This approach is particularly valuable when pest populations exceed thresholds that could harm crops or landscapes, making chemical control a critical tool for maintaining the health of commercial turf and other cultivated areas.

In contrast, the other options refer to alternative pest management strategies that do not fall under the umbrella of chemical control. These methods, such as physical removal or organic farming techniques, focus on different practices that do not involve the use of synthetic chemicals designed specifically for pest management.
