However, the term "pesticide" is rarely used in the legal provisions of the German-speaking countries.

Products used in the cultivation of plants, on the other hand, are not called biocides, but plant protection products. Biocides are also called non-agricultural pesticides for the purpose of differentiation.

Biopesticides are non-synthetic plant protection products. Compared to chemical synthetic pesticides, they are characterised by lower toxicity, higher selectivity, better compatibility with biological or integrated pest management. Such a biopesticide has been developed against bee mortality and consists of the poison of a tarantula and the toxic substances of the snowdrop. In contrast to conventional pesticides, it has (allegedly) no negative...
