biocide

This term describes a broad category of chemical agents designed to terminate biological life. It is most frequently encountered in scientific, agricultural, and environmental contexts, carrying a clinical and technical tone. While it encompasses a wide range of substances, it is often associated with the aggressive eradication of pests or pathogens. As a mass noun in many technical contexts, it can be used uncountably to refer to the general class of chemicals. However, it is also used as a countable noun when referring to specific types or brands of chemical agents.
