What is the term for a chemical used to control bacteria?

The term "bactericide" specifically refers to a chemical agent designed to kill bacteria or inhibit their growth. Bactericides are used in various applications, including medical treatments, disinfectants, and sanitation processes, to reduce bacterial populations and prevent infections. This precise action distinguishes bactericides from other chemicals used for different purposes.

Pesticides encompass a broader category that includes substances for controlling various pests, not limited to bacteria. Fungicides specifically target fungi, while insecticides are used to control insects. Thus, the context of the question focuses on the specific targeting of bacteria, making "bactericide" the most accurate and appropriate term.
