What is the definition of a bactericide?

The definition of a bactericide is a chemical that is specifically designed to control bacteria. Bactericides act by targeting and eliminating bacterial cells, making them crucial in various settings such as agriculture, food preservation, and public health. These chemicals can be effective against a wide range of bacteria and are essential for preventing bacterial infections and contaminations.

In contrast, the other options describe different categories of substances, which are not related to the function of a bactericide. For instance, a chemical that kills insects is identified as an insecticide, while a substance that enhances plant growth is recognized as a growth stimulant or fertilizer. Lastly, an agent that kills fungi is termed a fungicide. Each of these chemicals serves a distinct purpose, highlighting the importance of understanding their specific roles in pest management and agriculture.
