Term (lat. pestis = disease, caedere = kill) for chemical substances that kill, drive away or inhibit the germination, growth or reproduction of annoying or harmful animal and plant organisms. In the field of plant protection, this includes plant protection products and in the field of pest control biocides. In a narrower sense, pesticides are means of controlling animal pests, whereby the term was used in this sense primarily in English-speaking countries (pests). Pesticides are sometimes equated with insecticides. In a broader sense, however, the term pesticides refers to all plant protection products and pest control agents. According to EU regulations, there is a definition of "pesticide", according to which both plant protection products and biocidal products are covered. However, the term "pesticide" is rarely used in the legal provisions of the German-speaking countries.
