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. Pesticides and biocides include:
- fungicides
- insecticides
- herbicides
- plant growth regulators
- rodenticides (rat and mouse poisons)
- animal and bird repellents
- mole control products
- wood and masonry preservatives
- disinfectants
- human and veterinary medicines
- anti-fouling products
- molluscicides (snail and slug pellets)
- algaecides
- earth worm control agents.
Pesticides and biocides can cause significant water pollution and land contamination if there is an accident or they are not used in a responsible way. If they enter surface water or groundwater, even in very small amounts, they can have devastating effects. Pesticides and biocides can harm human health if you do not store and use them properly.
Businesses that use pesticides and biocides include those involved in:
- agriculture - arable, vegetable and fruit growing, pasture, livestock and poultry
- aquaculture - fish and shellfish farming (veterinary medicine)
- forestry and woodland
