What are pesticides and biocides?

Pesticides and biocides are chemicals or organisms used to control pests such as harmful or unwanted animals, plants, fungi, viruses or bacteria which cause damage. The term ‘pesticide’ is often used interchangeably with ‘plant protection product’, however ‘pesticide’ can have a broader meaning and may incorporate biocidal products. The term ‘plant protection product’ refers specifically to pesticides which protect crops or other plants, typically used in the agricultural sector as well as in forestry and public and private horticulture.

Plant protection products (PPPs) and biocides can cause significant water pollution and Land contamination, particularly if they enter surface water or groundwater. Concerns are sometimes also raised about their effects on human health.
