Term (bios = life, caedere = kill) for active substances, chemicals and microorganisms used in non-agricultural pest control against harmful organisms (such as rats, insects, fungi, microbes), for example disinfectants, rat poisons or wood preservatives. On the other hand, products used in the cultivation of plants, i.e. products used in viticulture, are not called biocides (although this is often the case), but plant protection products. Biocides are also called "non-agricultural pesticides". See Pesticides, and for pest control, see Organic Viticulture.
