What term refers to substances that can kill bacteria?

The correct term for substances that are designed to kill bacteria is "bactericides." This classification of chemicals specifically targets bacterial cells, disrupting their cellular processes and ultimately leading to their death. Bactericides are an essential tool in various fields such as agriculture, medicine, and food safety, where controlling bacterial populations is crucial.

Insecticides are used to eliminate insects, while fungicides are effective against fungi, and herbicides target unwanted plants (weeds). Each of these terms pertains to specific types of pests and pathogens, highlighting the importance of using the correct terminology when discussing pest management strategies. Therefore, bactericides are distinct in their purpose, as they focus specifically on combating bacterial threats.
