Biocides are chemicals used to control and kill harmful microorganisms. There are several synonyms for biocides, including germicides, bactericides, virucides, fungicides, and antimicrobials. Germicides are compounds that specifically target germs or bacteria, while virucides target viruses. Fungicides are used to control and kill fungi, and antimicrobials are broad-spectrum agents that are effective against a wide range of microorganisms. Other synonyms for biocides include pest control agents, sanitizers, and disinfectants. Biocides are commonly used in industrial, agricultural, and domestic settings to maintain hygiene and prevent infections. However, the use of biocides can also have negative effects on human health and the environment, and it is important to use them responsibly and with care.
