Which statement is true regarding chemical control?

Chemical control refers to the use of manufactured or naturally derived compounds to manage pests, and it encompasses a broad range of products, including those formulated from bacteria or viruses. These biologically based pesticides, sometimes referred to as biopesticides, can target specific pests without the broader ecological risks associated with conventional chemical pesticides. By utilizing the natural relationships and mechanisms found in nature, these formulations can effectively control pest populations.

Additionally, the other options do not accurately capture the full scope of chemical control. The claim that chemical control only includes natural pesticides is incorrect, as it includes both synthetic and natural options. Saying it is the least effective control method is misleading, as its effectiveness can vary significantly based on the specific situation and the pest in question. Finally, stating that it focuses solely on habitat modification is wrong, since habitat modification is more aligned with cultural control methods, while chemical control involves the application of substances meant to kill or repel pests directly.
